I am driving a 2000 civic si EM1 that currently seems to be set as low as it possibly can. I have tein super street coilovers. All wheels sit at a negative angle but isnt really that noticeable to the eye like how other slammed cars are. The tire size I am on is a 205/50 R15 and on all 4 tires the inside edge is bald, overall tire thread is pretty low as well though. Really soon im going to have to get new tires but before i do I want to correct the angle so that the new tires will burn evenly. I was thinking since the fenders arent rolled that if i roll them then I may be able to have clearance so that the tire can sit perfectly straight. Anyone have any insight on this subject? Please share. By the way the front wheels look like they already have sufficient space but then again the front is what turns so maybe they dont? The back tires look super tight though, I cant even fit my pinky in between the gap between the fender and the rubber so its pretty obvious why the rear wheels sit negative. It looks like I can gain a sufficient amount of clearance back there if i roll the fenders though, like a quarter inch. What do I need to adjust/swap out to get the wheels straight up and down again?

 

you have what is considered to be a very simple set up, with a very simple solution that has been solving these kinds of problems for a little over 25 years.

1. Raise the car up to about the point where it is only lowered about 2 inches from OEM height clearance. No Slammed or stanced look.

2. Purchase a front camber and rear camber kit
for the car.

3. Proceed to the most accurate alignment shop that you have in your area. Align the car so that it has no more than -1.5 degrees camber in either the front or rear with zero toe. The double wishbone system is so cherished because it can adjust for both

4. Do this with new tires to start off with. There is no saving your original tires that are already bald from camber wear. They are trashed, and makes no sense to "reverse" mount them. Drive & enjoy

 

^pretty much correct .

Its not "camber wear" as much as its wear from toe and camber . Mostly toe.

At the very least....fix your toe by having the car aligned (after buying new tyres).

 

Did you align the car after you lowered it?

If not, then get an alignment before you install new tires. The most critical angle is zeroing out the toe. If you have zero toe and -2 deg of camber you'll get 95% of the life you should out of your tires, camber isn't a wear angle, which means you don't have to buy a camber kit.
