Need help with my build. E30 M3 evolution

[AmuseS2K]

Hi All,

I need some help with my engine swapped E30 M3 Build for the Nürnburgring.

At high(er) speeds when I brake the rear seems to lock causing oversteer and makes the car spin out.

I think it’s caused by the differential.
But it could be suspensies too.. I’m lost.. any sugestions?

Thanks Guys!

Could be two potential causes. The wheels could be hitting the arches when the car brakes causing the steering to wrench. This can be fixed by increasing front body height and natural frequency.

Lift-off oversteer can be helped by setting anti roll bars higher at the rear, reducing camber at the rear, adding front toe out.

I'd recommend fitting a rear diffuser and possibly even a custom wing set at the rear since it'll allow you to run up to 300 downforce at the rear, which will keep the car more stable in general.

This is my suspension for our spec E30 class. The M3 is a very tail happy car. Key is braking in a straight line. Hard brakes, turn in and as soon as the tail starts its swing get on throttle. Hope you get it figured out
