Help with the '98 M Coupe

[freedomweasel]

I've been trying to set up my old M Coupe as it understeers quite a bit when it's stock. Currently it's about a full second slower than my stock CSL, despite it weighing 100kg less and having 12 more HP. It still understeers pretty badly, and I can't ever get the back end to step out. Here are my suspension settings any help would be appreciated, I'm pretty new at tuning.

Height -20/-18
Spring Rate 8/8.8
Damp(E) 5/5
Damp(C) 5/5
ARB 3/6
Camber -2/-0.5
Toe -0.02/0

I've got the LSD on the minimal settings all around.

I'd really like some more power oversteer, but no matter my settings I can't get it.

Try to put down the rear springrate to around 5-6, also the rear dampers to 3.. LSD, try set it higher.. Especially the initial tourqe.. The lower number, the more you spin wheels with less traction. You could try to fit the stock LSD also to see what the car feels like. How much HP do you got? Is it maxed out? Hope it feels better.

Also, put your toe out to -0,10

I thought a stiffer rear spring would give more oversteer, same with a lower setting on the LSD.
If I recall it has about 365hp, not maxed out.

Do you drive with pad or wheel? And which tire do you wanna use?

Pad, and it's on sports soft right now. Trying to keep it as a "realistic track toy" type car, and would like to keep sports of some sort on it.

Try this one out. Its what I did for mine, to use it at online races with pad.

Height -15/-15
Spring Rate 9.5/11.0
Damp(E) 9/9
Damp(C) 6/8
ARB 4/5
Camber 1.8/1.2
Toe 0.05/0.20

LSD: 15/25/10
Brakes: 5/5
Wing: 0/20

It works for me with nearly all tires. Maybe it will work for you to.. Change the LSD a bit, when you want, its adjusted for 467hp..

I'll give that a go and see how it works. Is the toe setting positive for both front and rear?

Yep it is. This car would lose the rear at corner exit with this setting, when you change the rear toe to negativ value. When you have problems there, than change the LSD accelerating value, before changing the suspension. High value will make the rear more loose and will give you more oversteer. A low value will allow you to accelerate earlier out of corners, but it will cause understeer.
