e92 M3 track handling improvements

[petrolheed]

I have an e92 M3 specifically bought for track use. I wont use this car on road.

I have installed KW Clubsport 3 ways, 265/295 18" tyres and made some slight weight savings.

I really do not like the way it handles. The body roll is terrible and there not much steering feedback.

I am looking for suggestions of ways to significantly improve the car with reversible items as if I still don't like it Im going to sell.

Thanks.

eta. I drove a friends CSL on track which at the time had a 'lesser' suspension and I immediately felt comfortable and in the zone.

Suspension needs more tuning. Get some sway bars and a square set of 285 tires, staggered on a track isn't as nice.

Bro you need to call a shop that specializes in racing e92 M3's.

^^^^^ this
suspension tuning wont matter on your body roll much like sway bars... thats wat you need. front and rear. dont add just front. I have it like this and it understeers too much.
also go square, but with nitto nt05 or maxxis rc1. those will also help a little on body roll.
i was also on the fence to change to an e46, but I am stubborn and I wanna try to make my e92 very enjoyable at the track.

What spring rates. Car is heavy it will tend to roll more.

Tires have no effect on body roll.

Too many variables at play to answer. Call up Geoff Steele (they build the finest track cars in the UK) and are somewhat closer to you (to build relationship with). There should be NO way the car should behave the way you have described with the hardware you have (alignment, height, shock setting... all comes into play).

Cheers,

If you went stagger and removed weight from the rear, the car isn't going to handle as well as you expect. (I am assuming the weight was removed from the rear)

Sway bars are what I had suspected I would need to improve things. I dont believe I need 285's on the front - Schrimer (Germany) are building some of the fastest cars at the Ring (Nurburgring) just now and they run 265/295 on 10/11" wheels.

Research I have done says the rear isn't worth bothering with but you reckon its worth doing both?

Standard spring rate that the Clubsports come with - 110Nm front and 120Nm rear plus helpers.

I'll make a point of contact with them to see what they can suggest but I mainly find these boys want your car and a blank cheque, whereas I like to build the car myself (not that thats working out well!)

Weight saved is mainly from interior - rears seats removed and all the rubbish in boot as well as front seats removed and replaced with SPG's. Weigh in around 1540kg.
