Saleen S7 Daytona Tune

[Trojan1874]

Can anyone give me a suspension tune for the S7 for Daytona. The back end of my car likes to slide a lot and I do not know how to combat that. Anything that you guys can give me would be a great help. Thank you.

Give us your current setup, and I can go from there.

Spring Rate: Front:10.5 Rear:10.5
Dampers (Extension): Front: 8 Rear: 8
Dampers (Compresion): Front: 8 Rear: 8
Anti-Roll Bars: Front: 4 Rear: 4

Camber Angle: Front: 0.8 Rear: 1.5
Toe Angle: Front: -.50 Rear: -.60 (Both are Negatives)

Max the front spring, and put the front/rear toe at 0.00.
Test that, and we'll go from there. (Let me know what the max spring rates are front and back)

 

[Trojan1874]

Front spring goes all the way to 16.5

The problem is I also want it to have good tire wear so I can race it in tire wear rooms

RH: max/max
16.5/11.5
8/4
8/4
2/6
1.0/1.0
0.00/0.00

LSD: 30/30/10
Let me know how it feels, worry about tire wear later on.

Yes

That tune is nice, a little loose but nothing I can't handle. I have another question, I have been racing in tire wear rooms that are 16-20 laps and the tire wear is very fast. I have my Enzo Ferrari tuned very well for Racing Soft Tires, but when I put on Racing Hard Tires so that I can make it to the end, I find that the car understeers very much and I have to lift going in to the corners so I don't end up hitting the wall. My ride height is 0 in the front and 20ish in the rear and my spring rate is 8.5ish in the front and 10.5ish in the rear. Is the understeer something to do with that or is it something to do with the dampers, camber, or toe? I don't want to mess with anything to greatly because I don't want to lose the tune that I already have because it is a great tune. I will sacrifice being a bit more loose with Racing Soft Tires on so that I can be able to turn and not have to lift with Racing Hard Tires on though. Anything you can give me would be greatly appreciated.

If it's too loose, stiffen up the rear spring by .5 at a time.
For the Enzo, it's essentially the same setup. Max ride height front and back, max front spring, and soften the rear up until it turns.

That's what I built for someone else.

For the Tire wear on the Saleen, the more negative toe in the rear, will wear the left rear faster than the right rear.
The more negative in the front, the more it will wear the left front than the right front.
Find the balance that wears the tires evenly, or the left side just a bit more than the right, and you can make a few extra laps.
The more toe you use, the slower it will be.

Will messing with the spring rate and the ride height affect how many laps I can get out of my tires on Softs
