Story:
I recently had my Hotchkis sway bars and Raceland coilovers installed. Currently, I have 18x8 rims installed (not sure offset...either +37 or +45) on 225/45/18 tires.

After having everything installed and getting an alignment, my car would rub a little from some bumps on the road, but the rubbing bothered me so I raised the front and rear about half an inch. After this, it would only rub if the bump is huge or if I was going really fast or whatnot. Overall, it was very drivable and that didn't bother me very much.

This weekend, I got another alignment adjusted to manufacturer's recommendation. After the alignment, the rear wheel would rub like crazy. IT would rub to the slightest body roll and the smallest bump on the road. Here is the specs before and after:


Question:
Since it didn't rub before the alignment, how do I fix the rubbing? I'm assuming that my wheels are a bit wide, so should I set the rear camber to -2.0 degrees? Is that going to wear out my tires like crazy and how does that affect performance?

On a related note, what alignment settings (camber, caster, toe) gives the best performance for street driving? I'm looking for something that gives good grip both when accelerating hard and when turning.

can someone tell me what they think at least? i'm going to get an alignment later today and i need to figure out the specs i want them to set it to...i appreciate the help!

 

Yea when they aligned it they gave you more positive camber, causing you to rub. Negative isn't all that bad. Especially -2 degrees. If worse comes to worse flip your tires when the inside wears out.

 

Ditto. Don't let "negative camber" scare you. As long as you're not running something crazy like -4 deg or something and the rest of your alignment is within spec, you're fine. I'd go ask them to set it at -2 or just over that and make sure the rest is good. Should help.

 

thanks for your responses

my friend got his evo aligned to a "mild performance" setting or so he called it...which he said was like -1.5 deg in the front and -1.0 in the rear. he said people with evo have tried that and got good street performance with that.

has anyone tested out and found what is best for a tC?

 

I'm running -2.0 up front and probably -1.5 in the rear (or close). Don't recall last time I had it aligned.

I have even more up front for autox... but those specs he mentioned would be fine for any daily driver.

 

I was running 18x8 with a +35, rubbed like crazy! Had -1 fronts and -1.5 rear. I didnt want to raise the car so i ditched the wheels, so i think the -1.5 in the rear wasnt aggressive enough.
