[E30ROB]

I havent hit the track yet but I will In the next year or so and I want my 128i to be setup just right. Maybe you guys can help.

Here is my current suspension/brake setup for best recommendations:
PSS9 coilovers
Solid rear subframe bushings
M3 control arms F&R
GC street plates (will install once I acquire Springs)
F30 BBK

My thoughts:
I was thinking
Front - 350lb 7”
Rear - 500 6”

The car will driven on the street, but I’m building this to destroy on the track and be somewhat tolerable on the street.

Thoughts and suggestions?

Thanks in advance!
