Hi, does anyone know what the ideal track set up for a stock suspension is for the track (camber, caster, toe in)? I have started tracking my car and notice considerable push and would like to edge it towards neutral. Thanks, Sean
Suspension Set up 4 the Track
- Thread starter swbatte
- Start date
first thing first...
I'll definately try the stock wheels and stock size tires and then play around with the tire pressure, as on the track, the tire pressure could play a very major role between confidence-inspiring or just plain scary...

Thanks for the advice. As far as my current settings go, I'm running with the factory specs and the stock wheels (16 & 15"). Last time at the track I ran tire pressures of 42 psi F&R.
There have been no modifications to the car as of yet. Although I am researching suspension mods for the future (NSX-R vs. fully adjustable setups etc). For now it's a stocker.

Measured cold, or hot? If measured cold, that's way too much pressure in the front.swbatte said:
What kind of tires are you using, front and rear? Brand/model? Size?
Otherwise, I agree with Ponyboy; worn shocks could be the culprit. They may lose compliance well before they actually feel soft.

Ken, don't you think, the presure is also high in the rear tires too? I'm pretty sure just adjusting to like 33/38 hot pressure will cure his understeering problem...
New Stock Components???
Thanks for the input so far! I'll reset tire pressures as suggested to the stockers (they wear Dunlop SP8000's).
The reason for the Dunlops is I went cheap knowing I'd buy new rims, which I have but have not installed yet. The new rims are 18/17" with Pilot Sports.
Would a fully adjustable coilover set up be significantly advantageous over replacing the current suspension with new OEM components or an NSX-R setup? (that's with the new wheel / tires)
Thoughts....

I would suggest you switch to the new tires first, with your current suspension, and see how they do. That will tell you how much of what you're feeling is due to the tires.swbatte said:
As for which way to go, that depends on what you're looking for from your suspension - compliance, reduction of body roll, lowering, road comfort, cost, etc. Oh and if you want to stay stock, the only "components" you would need to replace are the shocks. (Keeping the stock springs and switching to an aftermarket shock like Bilsteins is another option, and cost is similar to OEM.)
Yeah, go with new OE tires first w/ the OE alignment. Get rid of the Dunlops for track tires. If it turns out to be your shocks, you're going to have to decide if you can live with the ride comfort compromises stiffer shocks inherently come with. Tread softly, the "track pipe" is not for the weak of heart or the thin in pocketbook.

What happened when you went with the bigger wheels?

Understood. Your car is beautiful, btw (thumbs up).
Do you have a pic of your car at rest? I ask because your nose looks pretty low (too low) in the pic. So if this is under braking, I think you need to consider a different, stiffer springs. The real key is what is accpetable for you on the street in regard to comfort.
Maybe an adjustable shock like the Koni's would be a consideration too. If stiffness on the street is not an issue then to me NSX-R is extremely nice.
I was out with DocJohn recently at the Glen. He had just installed the NSX-R setup. I can only say one thing, that car is hooked up. With passenger (me) we turned some lightning laps. The car was so tight and predictable.

Hi Larry,
The pic is under hard braking so it may be a bit deceiving. Back then, my suspendo was Koni singles with Eibach springs - which I loved. I've since switched to the Comptech Pro and am trying to sort it out now. Umm, it's a tad stiffer than the Koni/Eibach combination.
