Slamming a '64 Bug
So I'm about to start the task of lowering my 64 bug. I have no experience with bugs but I think I have an idea of what I have to do.
Removing the plates is no issue for me, thats just bolts, levering etc (and watch for the spring plate release, haha).
The thing I'm trying to get my head around at the moment is the spines.
At this point in time the car is stock height, havent taken exact measurements yet but at a guess it looks around 20cm clearence.
I'd like the car around 8-10 cm clear when done, so going by a spline table I found on Airkewld, I need to rotate the outter splines by anticlockwise
2 clicks (or inner for 2 clicks clockwise for and extra 1cm)
Is it that simple? and at this height will I need to notch my spring plates?
Thank you!
Johnny

Remember that I think min ground clearance is 100mm in most states.
there is a table, inside and outside have divfferent rations. so you can use a combination of inside and outside splies to move the arm exactly.
I have no sympathy for my car, only the wallet that pays for it!
Go hard or go home!!!!

Yeh QLD is 100mm, fully laden, so realistically I shoule be aiming for 13cm or so unloaded.
I am aware of this but I want a low car for the time being, I may raise it later down the track but for the meantime that is the height I want to
achieve.
I'm also unsure if that law applies as the bug is pre ADR and some cars come out lower than 100mm from factory (which is legal) so who are Queensland
Transport to say it wasnt that low from factory

So will the spring plates need to be notched at this height?

here's another lowering table for spline amounts
Lowering chart
100mm is minimum height but also you are not allowed to lower or raise more than a 1/3 the distance from bumpstop to chassis.
madness is in the eye of the beholder  |

You need notched and extended spring plates if you want to go real low, or your rear end will keep you very busy trying to keep the thing straight,
and it will go through tires and bearings. lol.
What beam and tyres are you going to run?
dont think about the splines too much, you will get very confused, just measure.

How much extension is required? Is it dire that this happens?
We ended up notching 1" out of the plates at the deepest point.
From the measurements I took it's dropped approx 6.5cm, and I havent driven it to get it all to settle and bed in, so i'm expecting a few more
centremeters.

yes. sight down the side, you will see the rear tires toe in, with unextended plates.
you should go search on the samba, all the lowering info you need is on there.

I've been searching Samba and from what I can gather, 2 clicks will equate to needing a 1/2" extension. Does this sound correct?
