Dunlop Star Spec tire wear question

For your front to wear at the same rate you have to understeer badly all the time or never use the throttle. So yes you can achieve that, but as a DD on my 5th set of tires, no way.
My car is set up close to even with only a slight amount of oversteer. I wanted a little oversteer for the auto-x but not alot for the track. Like I said, it all depends on how the car is set up and how the driver drives it.

That looks like a great alignment, and is what a lot of reallly fast guys/national champs have ran in the past (in AP1's anyway...AP2 and Cr does not need as much toe in the back) Personally, I don't think that 1/8 toe out in the front is needed, but it's really a preference thing. You definitely need 1/4" in in the back at the very least if you really want a well balanced car everywhere that doesn't need to be driven sideways to be fast. I've tested everything from almost 0, 1/16,1/8, now 1/4 and 1/4 easily the quickest, most consistent and easiest to drive. I've found that on A6's (with a sample set of now 5 new sets of 4) that the rears where roughly 20% faster than the fronts. It does depend on driving style as many have said. I would say that if you are wearing the rears a bit more than the fronts, you are completely in the normal operating range and probably driving well. Good luck.

thanks for the input all!
until suspension mods arrive, the alignment will keep me happy. I am amazed at how great the handling feels! Still loop it once in a while, but much easier to drive fast.
captain pants - thanks for reminding me to rotate the donuts!!!

On the rears, that's the stock spec for toe in, correct? On an AP1 that is.

With 95% street and 5% track usage, I'm wearing rears at roughly twice the rate of fronts. Rear toe was set pretty low, too, like .15* total rear toe. Maybe it shifted...

Rear 2-3x more wear in the starspecs. No way to wear the fronts faster or even.

Even wear on the track and spirited runs. Rears wear more during daily use. Currently at 13k miles, 4 hpde, and many fun runs on the Z1SS. I wouldn't worry about what tires to get. They're good enough for what you want.
