E30 front end camber/roll Q's

[kamotors]

Ok guys so my car is running Potenza RE070's, the tire is extremely nice and the sidewall is the stiffest I've ever ridden on.

The rear camber/alignment is perfect, I hardly get scrub marks even remotley near the sidewall in the rear but on the front I'm rolling all the way off the outer tread blocks onto the sidewalls while corning making the car feel unstable.

SO My question is if I could do one thing what would you go with? a set of camber plates to dial it a bit more negative camber to stop rolling off the tread up front, or would you do a stiffer front sway bar like a 22mm ST bar?

the large outer tread blocks hardly ever touch asphalt cruising but the front rolls all over the sidewall. you can see where the dirty part is on the tire and how the camber is.

More pressure is the first thing that comes to mind. What are you running now?

Camber plates will help a ton. Ideally, you need camber, stiff springs, and a big sway if you're trying to push the limit.

I'm running 40psi all around, the grip is great, it really isnt under steering ever, the car has tons of grip, but I can physically feel it in the wheel when I go over the side wall and it causes a bit of an unstable/unpredictable ride.

decided to do both, order a front sway today and will get camber plates later.

40psi seems awfully high. Drop the pressure until the scrub (on track) moves over the outer tread blocks in front. Then adjust rear pressures until the car is balanced.

I'm already scrubbing past the outer tread block up front at 39-40psi.
