MPSS Rubbing - Camber = Better ?

[2014CamaroZL1]

So my MPSS 295/315 rub at the front and rear.
Has anyone rubbed, and then added negative camber and stopped the rubbing ?
Can we even add any negative camber with suspension ?
Thanks !

Are you stock height or lowered? If lowered, how much? I haven't looked inside the fenders, but they might be able to be rolled or cut down a little if that's where they are rubbing. I cut the lips on the rear of my 2005 GTO since they were so dang thick.

I have same set up on my 2013 vert with no rubbing. Where is it rubbing...when you turn lock to lock in front or?
Rears are they rubbing outside or inside.
What rims are you using?

I have the MPSS on stock 5-spoke rims and I have no rubbing at all. Car is at stock height, not lowered.

[2014CamaroZL1]

I am running the factory 10-spoke wheels with stock suspension.
The MPSS are the K1 version, which I think are 1" wider than the K2 version.

I have an almost full sized spare and a small sub in the trunk.
So I am probably riding a tad lower in the back than stock as a result.

The rubs occur under sudden compression, like a big dip or such.
The tires seem to be hitting the pointy ends of the bumper fascias.
I thought that a little less camber might solve/improve the situation.

Bringing this back to life, although, it might not be exactly the same situation.

Lowered to 635mm front ride height via Pedders Xa Coilovers. ZL1 10-spoke wheels. 285/35ZR20 tires.

Driver Front: -1.2 camber
Passenger Front: -1.3 camber

I have my alignment sheet set at -1.25 front camber, but what's above is what it ended up being. Obviously, my driver front tire is sticking out more than my passenger front causing it to rub on the inside of the fender lip. Will increasing the negative front camber help the situation? My passenger front is much better.

Lastly, will adding more preload to the springs on the coilovers help reduce downward movement (travel) when hitting a dip in the road? I have had a couple of opinions, but would like to hear more from you guys.

Feel free to ask me any questions about the situation.

Bumpity.

Slightly confusing, but here is my take:
285s on stock wheels should not rub unless you are just too low and/or soft.
The -camber may exacerbate that on the upper inside.
The variance in your camber side-to-side is not why you are rubbing.
The physical difference between the sides is minute.
Therefore, solutions include stiffening, raising, and or adding + a bid of camber.

It's definitely not too soft. My right coilover is seized. I tried everything about 2 weeks ago to make it budge so I'm kind of stuck at my current height of 635mm in the front. The reason I brought up the variance in front camber is because my driver front tire sticks out a bit while my passenger front tire is slightly tucked inside the fender.

I might have to flatten out the fender lip. This should help.

I'll be adding more preload today as well to increase stiffness, if possible. It's already preloaded a significant amount.

I'm just put MPSS 295/315 on my 2014 ZL1 and have no rubbing issues. K1 & K2 are the load raitings.

K1 7/32" tread depth, 11.5" tread width
K2 10/32" tread depth, 11" tread width.

Load ratings are the same.

I'm running the K2's stock height, no rubbing.

295/315 lowered, no rubbing and I have the stock alignment but not sure how close you can get on factory suspension. -1 is suggested with tolerances between -.5 and -1.5 on the front.

This might be beneficial for someone as well:

Just installed MPSS 295 n 315 no rubbing at all !! All I can say is wow what a tire n difference from Oem GY's.
