No one who has lowered their cars have had an issue with inner tire premature wear and or a solution to it??? I'm sure this is not a problem unique to me.

 

Have you tried taking it to another shop?

A mild drop like that can be corrected, not sure why you're having issues. I have Swift springs with a 1.6" drop and my shop was able to get it dialed in extremely close to factory specs.

 

I've taken it to 2 different shops.... there is no camber adjustment, so they get caster & toe in spec, but camber is always slightly off.

 

The tire wear, if you are referring to inner tire wear, is inherent and normal in this car. Specifically 2IS, 3IS, 1RC, 4GS.

The cause is dynamic toe change. You can mitigate it but not completely erase it. The trait is necessary to maintain the characteristics of this class of vehicle. Same w/ Mercedes, BMW, Porsche, etc.

The way to mitigate it is install stiffer front control arm bushings. Stiffer, but not stiff. The "fix" is OE RC-F or GS-F control arm bushings.

Your problem has little to nothing to do with camber. As long as your camber right and left is same or close, and not overly negative for both sides (more than say -1.5 to -2 degrees) you are fine. Don't worry about red or green, but worry about both sides being the same.

Unless you are slammed, then "Same" for both sides could be excessive. I'd need to know the specs of your car and/or your alignment sheet. 1.6" is kind of a lot.
Good luck.

 

One inch drop and the camber that comes with that is nothing to worry about. A little bit of camber like you have isn't necessarily a bad thing.

Our cars naturally have more inner tire wear due to how the dynamic toe is setup as E46CT has stated. If you do run into inner tire wear, I can almost safely say that it's the car's natural tendency and not your drop.

If you want a solution to the inner tire wear, I'd recommend purchasing the USRS by RR Racing. I purchased and installed it and it made a world of difference in how the car handles and feels. I haven't driven enough to see if it made a difference in tire wear, but I've heard nothing but good things from friends who purchased it for inner tire wear issues.

 

I have had USRS installed for about a year now. The car handles better, but I still have issues with inner tire wear in the front. My car is AWD so there is some camber adjustment available, but at its current lowered height I am still sitting outside of spec.

 

Is it an excessive amount of wear in the inner front? To my understanding USRS helps to reduce the amount of inner tire wear greatly but does not remove it altogether. A few of my friends who have had the USRS reported good things and told me that for their alignment, they just did their factory specs and made sure toe was zerod.

I recently had the car aligned and before that I didn't have much inner tire wear. I'll keep an eye out on it though!

 

Something went wrong, because I only got a month or slightly more out of a new set of tires with threads now showing on inner tire.... so I need to do something. These USRS's look like a definite must have. But of course, they are backordered.

 

Yeah I heard that they were backordered yesterday when a friend was looking to purchase it for his IS-F. Another option you have is the FIGs LCA bushings - from what I've read, if you're only getting them for a daily/grocery getter, then it makes no real discernible difference.

A little over a month for a new set of tires? That's not normal under any condition so try to call up the shop you purchased the tires from - there's usually a one year warranty on tires. I ran -4 fronts on my IS350 and my friend ran -8 fronts on his IS300 on slammed cars and our tires were usually good for 2+ years of daily driving which is why I said the one inch drop is not a big deal.

After you lowered it, the shop you brought the car to for alignment should've given you a paper with all your alignment specs. Can you post that? I'm on air now but I can try to find my alignment specs when the F was on springs since mine barely has any inner tire wear.

 

My Pilot Super Sports were showing cord on the inside after around 6-7 months of driving, about 5 of those months with USRS. My front camber was not able to be brought into factory spec due to my drop.

 

I don't want to repeat this again but E46CT and I both have clarified that your issue is NOT a camber issue but a toe issue. I've run -4 camber with a 4inch drop on my 2IS350 and had tires lasting longer than 2 years on a daily driver (granted, it had more than normal tire wear because anything over -2.5 causes faster than normal wear).

Can you post your alignment specs?
