drag suspension setup
pete wood - April 1st, 2004 at 10:58 PM

thinkin about doin some offstreet drags in my buggy eventually.
Anyone know what the ideal setup for front/rear suspension is? I know all VWs tend to axle hop. How do get around this and what shocks/ torsion bars are the go?
I have IRS + a bus box.

you need to brace your gearbox forks to stop axle hop, can you do this on your buggy? maybe braced to a rollcage?

You planning on running at WSID?

Might have to check with them before you get too many plans. They have a rule about the only open cars allowed to run are registered hot rods (pre-49 American origin).

I would think a roll cage and some sort of covering is as good as a lid but best to check.

Open vehicles are quite OK....if they are fully street registered and do not run quicker than 11.5s.
Just checked today.
cheers and have a ball.......

I think I can definitively say my g/box forks are adequately braced. Check my site.

I have one tranny strap at the moment (front). do you think I might need a back one as well?

On a side note, to speedster, where did you get your porsche spyder kit from? and is it registered in NSW with the tube chassis?

Just a thought, I had really tight shocks on the back of my beetle (bilsteins), if they compress easy and come apart with difficulty they are good for weight transfer, and drag racing (and wont wheel hop as easy), the other way round and it can induce a bit of wheelhop, or a lot - I managed to break inlet manifolds untill I changed shocks.

I also found more power helps.

Also check all your gearbox mounts and torsion bar bushes...

New Zealand built, comes under the "Individually Constructed Vehicle" guidelines.
Same as Cobras etc.

to speedster356.
So which company built it for you?
Does the kit normally use a subaru donk?
It is a big dollar kit?
Looks awesome :thumb

I went over to buy a kit, but found this complete one cheap. It was built for the Subaru, but it still retains the Porsche 914/T1V engine mounts etc.
It was built by Graham McRae Racing, but sadly Graham is now not building due to some health problems. There is no one building south of the equator now, and only available in the UK, Brazil and the US.
Hope to have back on the road soon.:cussing

is there a webpage for the company elsewhere in the world?
Is the individually constructed vehicle thing based on original spyder specs or was it a big hassle to get it registered?


speedster356 - April 5th, 2004 at 06:28 PM

BIG hassle.........still not fully certified. Things have changed in the last year and the aim I believe is to make this sort of vehicle (ICV) almost impossible to get on the road.
Check out http://www.vintagespyders.com,http://thunderranch.com for the US manufacturers.
The first molds were from an original Spyder then modified in the windscreen area to take a Speedster screen, the rear wheel humps were modified as well. They might also have an extra 50mm in the door length?
Also try Spyder forum
