Suspension and alignment details required
speedster356 - May 9th, 2006 at 03:42 PM

Car has, ball joint disc front end adjustable (stock shocks)and Porsche 914 rear trailing arms with Koni coil over shocks. Car weight is 750kgs. No sway bars at the moment.
OK, I'm getting some alignment work done in the next couple of weeks after changing the rear trailing arm pivot rubbers (now bronze) and a couple of ball joints on the front. What I'm looking for is some basic targets for the rear and front geometry. I've also modified the rear pickup point so as to take out the huge neg camber I had on the back allow some adjustment.
What's your thoughts?
Front caster is fixed.

Bronze pivot bushes WTF.


speedster356 - May 9th, 2006 at 06:24 PM

Yeah, new bushes are manufactured by http://elephantracing.com the other option was full poly bush or a needle bearing setup.
What camber do you run in the front Craig?


hellbugged - May 9th, 2006 at 07:21 PM

3 to 6 degrees negative camber

Bronze?! What do you have on teh outer pivot? Where;s the 'give'?

Street or track?

speedster356 - May 9th, 2006 at 08:22 PM

I don't want no give:P Track.
Bronze bush with a thin outer poly layer (they can't be sure the housing it presses into is concentric) v steel pivot pin.

I think you do want some 'give' otherwise you will get 'bind'!

My car is 1.5 deg camber F, 1 deg R, 5 deg caster, 0 toe both ends. Good road setup, I reckon

So my results were today
Front caster : 8.4 deg (welded in beam)
Front camber : - 1.5 deg
Front toe in : 1.0mm total

Rear camber : -1.7 deg
Rear toe in : 3.0mm total
Rear caster : can't find the reading!


VWCOOL - June 21st, 2006 at 08:10 PM

Looks orroit - but gee that's some caster for a lightweight car!

It will not necessarily bind if suspension and steering geomentry is aligned correctly..Ie formula one cars have rod-ends, not bushes.

I need to get mine adjusted also..I have a fair wack of neg camber on the front. Castor needs looking at though as still gets sketchy above 160. Is better since first set of shims.
