Hello

Car:
Euro M3 3.2
Allingement:
front 2.5 Camber, 0.0 Toe
rear 2.0 Camber, 0.3 total Toe
Tires are not stagered
Koni SA are f/r 1 turn from full stiff (it seem the car is a little lose, i like more then when the shocks are tigher, i have more response from car)

I have first built in the GC co's SA with 525/600 stock sways
- Turn in are not sharp, need a lot of initial steering, but feeling are like the car rotate in his center, to take a set is easy, the susp. sucks big bump very good, car seems to fly (surprise for me).

Then i have swapped to 450/525 stock sways,
- Turn in are sharper, less steering needet, to take a set is easy, not as stable as 525/600 (of course).

Then i have swapped to 450/525, Eibach Sways 26mm,24mm
- Turn in are less sharp then with stock sways, but after appex it is sharper, , to take a set is not as easy like the others.

Overall i love the 525/600 most, but i want better turn in.

Any Advice?

Try tightening up the Eibach swaybars. You also need more front camber with that much rear camber. Try going for 1.0 degree more camber in front than rear...i.e., go to 3.0 front.

There are several things you can do to cure the unresponsiveness of your front end. Sounds like you've tried some of them. But, your results are a little confusing.

Basically, things that increase roll resistence in front should cause the front to react more quickly. At least, up to a point. Stiffer springs, more shock bump and stiffer sways. But, you state that larger sways made it worse. That's confusing.

If it were me, I'd stay with the stiffer springs. I run 600/650. With the Koni SAs, you can't adjust bump. I'd also go with the aftermarket sways. With them you benefit from adjustability.

Here are some things you can try:

1) As Maranelloman said, go with a little more camber up front.

2) Use front spacers to increase the front track.

3) Go with a little toe-out up front.

4) Check your ride heights. If your rear is too low, releative to the front, it can cause understeer. GC recommends 12.5-13" front and 11.5-12" rear, measured from the wheel center to the top of the fender arch.

5) You may also get some benefit from higher tire pressures in the front.

Good luck - Jay

you need more camber in the front. a minimum of -3.

Another thing you could try. Soften front rebound or stiffen rear rebound. I was going to say you probably could use some more out back.

At First

thanks to all :thumbup:

[jayhudson] your results are a little confusing,
yes i know, but i have do the same install 2 times to find somethinges else,
but it was like i wrote.

So i can sort out:
- because big brake, the front track is 27mm more (this point is ok)
- Ride high is on GC recom.

Have to try:
1. will do 3-3.5 camber at first
2. soften front rebound or stiffen rear
3. tightening up the Eibach swaybars (in front), yes possible 2 steps more.
but this will increase understeeer ? Hmmm .. will try! :rolleyes
4. more pressure in front tires
5. little toe-out up front
6. go setup 600/650, for SA i think is the max?

Let You now what happend .
