I'm on H&R coilovers and 18"works. Will I eat up my tires if I don't?

 

You need to get the car aligned after lowering. With a 1" or 1-1/2" drop a good alignment shop can get the car back to factory specs without any kind of kit.

How much is your car lowered?

 

It was lowered when the coilovers went on, but now that the 18's on, it needs to come down another half inch. Hopefully there'll be no fender gap at all, so fairly low.

 

car is adjustable from Honda, you don't need a kit.

 

I doubt you're low enough to have problems achieving proper camber. Have the car aligned at a good shop, and don't worry about it unless they can't get the camber where you want it.

I'm dropped an inch in the back and a little over an inch in the front, and I have adjustment to spare (and I'm running UK specs, which call for greater negative camber). You really have to slam the car before camber adjustment becomes a problem.

Have you had the car aligned since it was dropped?

 

There are kits that alter the range of camber adjustment, though I doubt he needs anything more than a good alignment.
