Camber or wider tires?

[Khyron686]

Stock shocks on RCE Yellows, with whiteline camber bolts. 17x8 wheels.

Haven't gotten an alignment yet but at max negative camber I'd expect -1 to -1.4 . Problem is even with stock 215 tires, it's 10mm from the strut base. With 225 will be close, 245 for sure. I can grind a bit of the base to make some room, but as it stands for autocross would you reduce the camber and put in bigger tires or stick with narrow tires max -camber? No intention of getting coils on this car (DD).

I had RCEs with camber bolts with a total of -1.2 camber on each side, with 17x8 +45 wheels and 245/40 Hoosiers, and then RE11A. The Hoosiers rubbed on the spring itself, not the perch, on tight corners, the RE11A did not rub.

Crazy - I can't fit my pinky between perch and stock tire with my whitelines, but maybe some of that is the rub strip/protector thing. If I can run 245's I'll be thrilled so your post gives me hope.

Question remains though - 215 on -1.5% or 245 on 0% which would you pick for a relatively tight parking lot autox course?

I'm running 17x8 +45 wheels with 245/40 ZIIs and -1.3 from OEM camber bolts and RCE Yellows. No rubbing or issues, though the fit is TIGHT. I have plates coming in this week though as -1.3 just isn't enough and has led to excessive wear on the outer edge of the tire and understeer. So I would say both.

The answer is yes. Or "C - make it so I can have both big tires and max negative camber"

You can have both on these cars. And when s2d4 said offset, he wasn't necessarily *just* talking about spacers. For instance, you could buy wheels that gave you the extra offset. Spacers will also do the job. Another option is wheels with a little too much offset, and machine the hub face back so that it fits. All viable options.

Barring that, it also doesn't need to be "all or nothing." If you're closer in there than you want to be, give up some camber. You don't need to get rid of all of it. But like we said, 245/40s fit under the stock fender. You would be best off figuring out a way to make that happen within your budget constraints.

Ultimately, though, why not have both? You can. And for not much money, either. I'd much rather explain why I had to use spacers when talking about my strong finish than praising the $50 in beer money I have in my pocket by resigning myself to a sub-optimal setup.

Set camber based on tire temps across the width and/or by monitoring wear on the shoulder.

If the outer edge of the tire is hotter than the inside, and/or you can see wear over the shoulder you need more camber. Going to a wider tire will likely make it worse since you'll be generating more grip.

10mm spacer (or +35 wheels) will give you lots of space for the camber you'll want and more tire if you choose to go that route.

I know that would be your problem since you left out the most crucial info when starting this thread.
Why did you buy +48?
