So I got these 15mm kics spacers for my front wheels. These are the ones that you bolt onto the existing studs. The spacer itself has studs for the actual wheel.

I notice that after I installed them for about a month I started getting a lot of wear on the insides of the tire. The answer may be obvious, but I was wondering if you are suppose to get an alignment with the spacer on, or if it doesn't matter.

Perhaps my alignment is just off.

 

I doubt its your spacers. Have your alignment checked. is your car lowered?

 

Nope not lowered. I guess I'll stop by Firestone to get it aligned.

 

yep, your toe-in is too much. have them set it at 0.03 per side total 0.06 degrees on
the front.

 

damn, how do you like the Kics Project spacers?? those are dope.

 

Assuming that it's not causing these wear issues, they're great.

My offset in the back is real aggressive, +15 on a 9.5" rim. I figured I'd try to even it out on the front wheels. +40, on a 8.5" rim without the spacer, +25 with the spacer. I think by widening the front track, it's suppose to introduce a little bit more more oversteer which equals more fun for me.

 

I was just reading up on camber, caster, and toes. Being the amatuer, I thought that it may be too much negative camber. Do you think it is really too much toe-in since the wear is on the very edge of the tire?

If it is a toe in problem, perhaps the spacers may have amplified problem? Since it is further away from the original plane.

I was hoping to get another thousand miles out of the tires, but I think I may need to replace them. It must have been the pothole that I ran over a month ago. I'll probably get the lifetime alignment at Firestone.

 

My toe specs were off.

-0.01 on the right front and 0.18 on the left front. Hopefully my wear gets better now (or rather doesn't get any worse).
