Wheel alignment data

Post by Aldo »

Hello guys,

I am looking for the correct wheel alignment data for my E21. I couldn't find anything on the forum though. I have a lowered E21 with GAZ coilover, PU bushes all around and camber and caster adjustable top mounts in front. I will use the original wheel alignment data if anyone can point me out to it.

This is the data i found, perhaps anyone can confirm or give an advice about what to change if i wanted it to be more grippy/ sporty.
Front toe in; 1.0-2.5mm(0.039 to 0.099 in) to 3/81
1.4-2.6mm(0.055 to 0.102 in) 4/81 on

Camber ; not adjustable, but look for about -1.2 degrees total with camber plates
book says -30' to 30'

Caster -7.5 to -8.6 degrees

Rear:Toe in 1.2 to 2.8 mm(0.047 to 0.110 in)

Camber -1.3 to -2.3 negative
But if someone has a more sporty setting with adjustable top mounts that would be great.

Thanks

Depends on if you're driving it to work everyday or just taking it for a blast on the track at the weekends.

For track and weekends only...
I'd reduce the toe-in and increase the camber at the front.
If you reduce the toe-in, you'll reduce understeer, but, you'll be less stable when braking. I wouldn't go to toe-out, but up to zero toe-in has been ok for me.
I've run up to 3.5" neg camber on the front. Rough on the tyres, but good in the corners. Maybe 2.5" would be OK.

Good luck. For the best results, you should change one thing and see how it goes. If you like it, change something else. If you change too many things at once, it can confuse which change had what effect.
