AC Schnitzer suspension

[8ARF]

Good evening guys,
I have the ACS racing suspension on my non CSL M3 and looking to do something with the springs.

I seek advice on what poundages would work nice with the ACS dampers and which manufacture of spring would fit.

I believe the Bilstein PSS10 kit is virtually identical and according to TMS, a range of springs can be sourced.

My aim is to have a (even) lower ride height with more aggressive spring rates.
I would be nice to combine a lower, firmer spring with the ACS dampers as I find the car just "nice" on the road and quite handy on track.
I am prepared to sacrifice some ride comfort to achieve my aim of a not too compromised road car combined with a more capable track car.

Other mods are Eibach arb's, ploy bushes, limiter kit, rear adj arms, TMS mounts. All the parts are either here or on the way from the U.S.

Is there anyone out there who may have some info or experience to share?

Thanks

Ian
