Guys,
What's the recommended negative camber setting for a daily street car, front and rear? I'm thinking perhaps somewhere between -1.0 to -1.5 degrees all round ![]() Anyone beg to differ?

Thanks. That's with the factory suspension and FUCH's though, right?
I run KONI adjustables all round as well as 235/40/18 up front and 285/35/18 on the rears ![]()

Well, I ran -1 front and -1.5 rear and it worked well, nice even wear if you have sticky tires and drive aggressively, but I'm not sure if the big 18's would like a bit less or a bit more or the same. It would probably be a good starting point.

The more negative camber, the more you run on the inside edge of the tires.
For mildly aggressive street driving with your extra-wide tires, not more than 1 deg front, and 1.5 rear.

Would -0.5 front and -1.0 rear be good on 17"?

I actually got better turn-in with less front camber. If you have a stiff suspension that doesn't roll much at street speeds, too much negative camber will give you a longer contact patch just when you need a wider one.
So with stiff suspension, maybe -.5°. With stock suspension, probably a bit more would work best. |

How would you know if more negative camber would be better if you've never baselined your experience from factory settings?

By trial and error.
0.5 front and 1 for the rear sounds good to me for street driving. I tried a few different settings and this feels good to me. Many threads and posts and opinions on this issue and too many confuse street driving with track driving.

Shouldn't camber be setand fine tuned by recording tire temps after track driving or street driving (then look at tire wear)?

I'll see what the workshop recommends, but I might suggest -1.0 and -1.5 to them to see what they say.
Thanks.

merv
there's much much more to it than just camber. i find front toe adjustement to have a huge affect on the handling of my RS rep - particularly turn in. find a specialist suspension shop and let them set the whole shooting match - camber/castor/toe/rake/ride heights etc. the setup i use now came from giving the car to a suspension shop with the instructions: "i'm off to targa tas next week, do your thing". also, get them to corner balance the car with a weight equivalent to you in the driver's seat.

Depends on how aggressively you drive and how long you want your tires to last. I ran with 1.0 front and 1.5 rear and went thru a set of tires in about 8000 miles (Yokohama AVS Intermediates). Went with 0.5 front and 1.0 rear and tires now last about 12000-15000, but still get most wear on the inside shoulders of all 4 tires.

Hi Ryan, yup, it's going to be corner balanced and aligned too, but I just wanted some advice on the camber settings cause my old P-Zero's wore out real fast on the inside. The -ve camber was just way too agressive and they wore like a mofo. For a daily street driven car, I want these new tyres to last as long as possible

On the street, its pretty much entirely a tire wear issue, particularly if you're running stiffer suspension than stock and big tires. Some guys deviate to get fender clearance, but you've got a widebody, right?
On the track, its another issue entirely and it depends on what your tires "like". Toe, on the other hand, is instantly noticeable. In on the street, neutral or out on a track/ax car. With big tires, neutral or out on the street really increases driver workload.
