Ideal camber setting for track?

[erik325i]

What is the ideal camber setting for an e30 at the track?
I have both the front and rear set to about -2.2* right now. I know that is not nearly enough camber up front, but what should I set it to? -3*? -4*?

What about the rear? Is -2.2* a good setting in the rear, or should I want more?


In case you're wondering, I am running the C3 Motorsport coilovers with 450/750 spring rates, cabrio front swaybar, and no rear swaybar.

I get even temps accross the front at about 3.5deg

what tires will you be running?

I am running 2.9 in the front and rear on the street...

At the track i just max out the front.

I have the same setup as you minus the cab sway bar, i am running stock for now.

That's the way to do it. If you're more patient, tire wear can tell you also.

The biggest factor will be driving style. More agressive, faster = more camber.

camber

temps tell alot.........


I run 3.2 up frt/2 in rr.....it also depends on tires......I run RA 1's....toyo rec's at least 3. You run rela. hi rear spring rates...do u oversteer?..more neg camber will increase that.....2.sumthin is not nearly enuf for e 3o's in general.

I am running Toyo T1R 215/40-17

Maybe I should invest in a tire thermometer...

Ha, we posted at the same time, so I didn't see your post until now...

Anyway, regarding your question about my choice of spring rates... Yes, I do have very high spring rates in the rear, but I do not oversteer at all because I have NO rear swaybar, and the slightly thicker cabrio front swaybar. My car handled almost perfectly at the track. I just needed more negative camber (hence this thread).

What about the rear camber though? Should the rear have just as much camber as the front? Most lowered e30s suffer from too much negative camber in the rear... What is the ideal setting?

No. Not nearly as much is needed in the back. 2 degrees should be a good starting point.

And dont go full negative on the front. I have the Vorshlag plates and full negative is like 6 degrees. Way too much!

The ideal camber is the setting that keeps your tire temps constant across the face of the tire under the conditions you want to optimize the car for.

This will 1ish on the street, more on track obviously.

The Vor. Plts. alow that much?.....wow. What shocks /sprgs do you run?......what size wheel/tire?......those plts appeal to me.........

The plates are very nice. They also have the beefiest spherical bearing I've ever seen on a set of camber plates.

Vorshlag plates are the only ones to run IMHO.

..oh, so you run c/o's......


Im just thinking w/ stock style springs like HR or Turner JS one would not be able to go as far as 6 neg camber.... I think c/o springs are narrower giving more clearance inside the fender well(?)......no biggie, its not like I want neg 6!
