Its going to be easier to keep all the suspension components Tein which is grear becase thats one less thing to have to go re-inventing. The caster
tops that I am looking for will be something like these.
I will be slotting the mounting points so I can set a static castor of 5 degrees and make it adjustable to about 8 max. Static camber will be .5
degrees at the limit of the pillow-ball mounts and will increse from there.
I'll be using the ABS sensor as an input to the speedo. A lot more tidy than a cable and some crazy and unreliable autometer cable to electronic
speed sensor.
Cheers,
Ian

Defiatly not running ABS. Its way too complicated and I'd have to pull the entire system from a porsche 944 to adapt all the electronics and ABS
valve hardware. If I end up with an autronic ECU though it is possible to use the speed sensors on the wheels for traction control. Also most ABS
systems are a waste of time in my opinion. Its for people that dont know how to drive and panic when they hit the brakes. I've yet to have the ABS
kick in on my GTR, and believe me when you stand on the brakes in that the car really pulls up. Brembo monoblocks and Endless pads and rotors help.
The brakes on the bug will be 944/brembo 4 piston calipers all round with zimmerman cross drilled rotors and EBC red stuff ceramic pads.
Today saw a fair amount of progress. I finished off the supports for the mcpherson struts and welded them solidly in place while the whole assembly
was sitting in the car. Ive allowed for 10mm of clearance to the bodywork from the back of the strut support. As you can see from the first pic there
will be enough room for me to run a diagonal from the inside back of the strut to the center of the tunnel to brace them from flexing inwards and
later with a strut tower is added, it will stop side to side flexing.
And last of all I started on the mcpherson strut towers. They are made from 5mm flat bar. They still require considerably more trimming to get them
right. I thought I had it sorted with cardboard templates, and then started aligning the base settings of 0.5 camber 6 degrees castor... after i'd
already cut my material. Not so smart but anyway. On the bright side I need to remove more material and not add it.
Tomorrow I hope to finish the passenger side strut tower and template all the parts for the other side. I dont get a full days work on it tomorrow
though as ive got to go to work briefly in the morning and have to start the family christmas thing around 3:30 or so tomorrow afternoon.
Thanks for the feedback too guys.
Cheers,
Ian

On christmas eve i finished tack welding the passenger side Mcpherson strut tower together with the camber and caster set where I wanted it, so today
I set about finishing it and the drivers side as well. The are now fully welded on the outsides and when the chassis is flipped over I will weld the
insides of the plated sections as well.
I've welded the round bar that joins the towers to the chasis to the frame head. So all in all i'm happy with todays progress. The front end is now
self supporting. All that remains is the cross bracing of the towers, finishing the rear tower mount, drilling mounts for the steering rack, and
finishing the front of the A-Arm mounts. That will be tomorrows mission.
Here are the pics.
Cheers,
Ian

Regrettably I didnt weigh the front end before I did this conversion, but as it is at the moment I can still lift the entire front end of the chassis
with wheels and brakes attached and it seems lighter than the ball joint front end that I had removed. When I get a corner weight measurement done I
will know for sure. Has anyone ever done a corner weight measurement on a stock beetle?

If you are considering doing it, getting a superbug chassis as a starting point is where i'd recommend starting. THats if your not wanting to
increase the wheel track width at the same time.
Have a look at what this guy did with his front suspension conversion.
http://www.veewrx.com/
In my situation it was actually easier to use a king and link or irs/Bj pan, as the A-arm mounts are completely different to the VW mcpherson strut
arms. All the reenforcing in a superbug pan would have been in the wrong place which would have meant unnecessary weight.

Today I made finished most of the front end off. I still need to do the rear mounts for the strut towers but im saving myself the pain if trying to
weld upside down and will do them when I flip the chassis over to do all the under side of all the welding. The steering rack is bolted on now too and
i've added a re-enforcing bar to support the drivers side rack mount so that it links it to the frame head.
I also started on chassis re-enforcing. The lower plate extends through to the torsion housing tube either side of the gearbox mount. The upper
triangle then ties it into the body mount. One more plate section will go from the torsion housing to the other side of the body mount to fully box
in the torsion tube to limit its movement. An idea I kind of stole from Westi's build. I am still undecided what I am going to do with the rest of
the pan. I think I will be welding in a few mounting tags and then bolting in alumunium floor sections. This will mean adding a structual support from
the front frame head to the rear corners of the pan so that the outer edge of the torsion housing is also re-enforced. Trying to do this without
adding a heap of weight will be the goal.
Tomorrow I'll be finishing the re-enforcing and adding a rib over the gearbox to create a new section that the body can bolt on to. I am not sure how
much the body will need to be clearanced for the gearbox yet. That will be worked out on the big day when the body meets pan.
Cheers,
Ian

Hi Ian what a great car! Wondering how you got the correct info as to setup the front suspension re ackerman etc, did you just transfer the porche
setup? I ask as with your setup any rear facing a arm could, in principle be used ie subaru. The steering rack used, was is chosen for being the
correct width to use with the porche a arms? Again great job and cant wait to hear how it progresses. Mike

I transferred the porsche setup. I did try calculating everything out using two programs that produce a whole lot of data but in the end it just got
too complicated. I then approached the whole setup from a diferent perspective and went researching for info about alignment of 944's and 911's.
Both used simular settings regarding camber and castor.
With regards to steering and ackerman angles I didnt look into that other than to note the location of a factory steering rack on a 944 and to try and
get a steering box in as simuar location as possible... Which isnt possible. The 944 rack is mounted slightly forward of the spindle ball joints and
low at the height of the inner A-arm mount. I wasnt able to get exact measurements. The 944 ball joint goes on the bottom of the spindle. So by using
a ball joint flip kit I will achieve nearly straight steering rods from the ends of the rack. It was just luck that the width of the 121 steering
rack was also nearly identical to the width between the rear A-arm mounts.
A much easier rack and pinion conversion could be done with a rack from something like a handy van, or any other mini van. Having the rack operate
reverse to a normal rack would allow it to be mounted in between the front torsion beams. It makes the whole installation a lot less cramped and also
makes the steering a lot easier to hook up. The spindles would also be swapped left to right.
Today didnt see a great deal of progress on the car. I've finished the drivers side plating around the rear torsion housing so its the same as the
left, and started on the rear suspension/roll cage support mounts. But then I ran out of steel and welding gas and cant get more till monday or
wednesday next week. Bummer, going to have to relax tomorrow.

Hi Ian
Will mounting the steering knuckles and A arms back to front as you've done affect anything? I can see why you've done it that way, as the A arms
fit much neater that way.

ackerman is not to be ignored it affects turn in and bump steer. ackerman is the line drawn from balljoint axis thru steering arm pivot to rear drive
line centre. great gains in handling can be had by making the steering arms adjustable and tuning in to suit your driving style ie are you a late
braker and chose a late apex then positive akerman can help with turn in making the inside front have more toe out pulling the front in harder. if you
get all of your braking done before turn in then less akerman may suit as getting on the power earlier tends to make the front less nervous tending to
more oversteer.

I didnt mean to say i'd completely ignored ackerman, its just that a lot of measurements on the 944 and the vw are the same. Wheelbase for example
is 2400mm on both cars. The track on the 1988 944 turbo is 1735mm and my widened chassis track measures 1730, so the ackerman will be very close to a
944. A standard beetle is 1540mm and I am just under 100mm wider both sides.
That ive put the spindles on the wrong way round is a massive screw up. Thanks for spotting that Steve, I dont know how i missed it. I was looking at
pictures of a removed front end that was incomplete and had been removed from the car. I had assumed 944 was simular to 911 which I had also been
looking at. On the bright side I get to move the rack and pinion to in between the torsion housings which where I wanted it in the first place.
Swapping them shouldnt affect camber and castor. Not having the rack where it currently is will make my water, oil and cooling hoses a lot less
cramped too which is a bonus. I have to run 6 pipes from under the tank to the back of the chassis.

Made a little more progress today. I've got the rear coil over shocks 1/2 finished. Note to self if i ever do this again I must buy a pipe notcher,
because notching pipes with with a grinder is a pain in the ass. The gearbox still lifts in easily under the horizontal bar provided I remove the
starter motor first.
Tomorrow i'll do the plates that the coil overs bolt onto.
Ive reverse the steering knuckles too and re-measured everything and have ordered a porsche 924 manual steering rack which should arrive in 3-4
weeks.
Merry new year everyone!
Ian.

I like the way you have the steering knuckles it lends itself to better geometry and a better centre of gravity. This is a great project would make a
great track car. thanks for taking us along for the ride

Yeah im making an effort to move as much weight forward as possible. Im relocating the battery to the front, the dry sump tank will be up the front
too, as will the water-oil heat exchanger and a fuel cell instead of the factory tank. Now there is no tie rods under where the tank is, I will have a
lot of room there too which is very helpful.
Today I finished most of the rear coil-over arrangement. I still need to make up the bottom mounts as the bolts for the bottom of the shock are way
larger than a normal vw lower shock mount. I think its a 16mm bolt which is great because its way stronger than standard 12mm vw bolt. I am going to
make the lower mount adjustable so I can change the height of the rear end by changing the position of the lower mount. The chassis is now entirely
self supporting and rolls nicely.
I still have the steering and the rest of the floor pan to finish, seat mounts, fuel, oil and coolant lines to run, so i am thinking its about a month
off completion if all goes well. Here are the pics.
Cheers,
Ian

Yeah I came across the eyeball engineering front end on the germanlook forums. Down side is that the rose/heim joints are not legal for use on
australian roads. Not to mention they would last about a week on Cairns roads too. Though it would be a great basis if you were to buy it and modify
it using more conventional suspension bushings.

Let there be steering. Today I finished installing a Porsche 924 steering rack in the front end of my chassis. It turned out very nicely. I still
need to lengthen the steering rods a little and have discovered I need new tie rods as well. But who can complain when you pay $50 for it. Freight
was $130 from the UK though, but thats way cheaper than $500ish that Australian porsche dismantelers wanted for a rack that needs a rebuild. Aussie
porsche parts dealers price things like everything is gold plated.
Next on the list is a diagonal bracing for the strut towers. Here's the pics.
Factory tie rod end location.
Tie rod on top, where it will be after a flip kit is installed in the spindles.
Other news is that I met with an engineer again 2 weeks ago. I will be having the chassis mods inspected in a about a month but I dont foresee any
issues in getting it all approved based on what he has told me.

That was part of the plan, but a new QLD transport ruling has been passed that means cars with cages may well be un-registerable. I dont know all the
details but I think its something to the effect of unless its a porsche GT3, its not legal.
Anyone else know anything about this?
I'll still be making a cage up, but it will have to be able to be un-bolted so it will probably be just a 1/2 cage. If I were using a body that wasnt
already painted it would be nice to be able to weld the cage into the bodywork so its just reenforcing and isnt really just a cage anymore, like they
do with circuit racing cars.

I think its the beginning of QLD transport trying to crack down on modifications for all vehicles. Technically anything that is not OEM equipment is
not legal under QLD transport rules. If they are serious about it and enforce it, it could take 90% of the cars off the road. A prime example is
having an exhaust system replaced with a non genuine part by any exhaust system repair shop... illegal technically.
There may be a loophole under ICV rules.

if you don't put a full cage in the car all your lovely work that you have done will be for nothing,with the power you are sugesting and grip that
the suspension and wheel base will produce.it will crack body and pan,it is too much stress for the poor old girl.you need to find away of stoping
twist.some bracing from front to back or cage or both.
anyway that's my 2 cents.keep the pic's coming.love you work.

Yeah your right westi. I'll have to have my engineer read up on it. He told me he has the updated documentation but hasnt bothered reading it yet.
If ICV is the way around it so I can run a cage I may have to go that way instead, even though its a lot more work. I really dont want to have to put
cats on the engine too, or hazzard lights, or side indercators... or any other non-period crap for a 1966.
I didnt get a lot done today. Went on a car cruise instead for lunch and then spent the afternoon working on the car. I've started on the passenger
side floor pan changes, and also added some diagonals to the front strut towers. There will still be a strut brace to tie the top of the strut towers
together that will be going through the body, but the small diagonals should be enough.
Here's a pic.
