just ordered koni yellows with ground control coilovers. Spring rate is 550 front and 450 rear. I know this is a very common setup so I was wondering if I need a camber kit to go with it? Looking to drop it 1.5 to 2 inches. If so, I was looking at spc ball joints and ingalls camber kit, which one should I go with if needed?

 

no you don't need it. I have the same setup and went through the same thoughts.

 

cool. Just worried about eating up my tires from the camber. Thanks

 

Toe eats tires, camber can cup the rear tires but regular tire rotations stop that.

 

Camber doesn't eat up any tires by itself when it's in reasonable moderation (-2 to -3 degrees). Just get the toe straight.

 

Although it goes against what everyone else says, I'm dropped on GC's and had my toe within spec (checked several times) and was eating through tires on the inside edges. I finally put on a camber kit (kmac) on the front and put myself at about -0.7° on each side and the problem went away, for what it's worth. I still have a similar problem in the rear; I have the spc kit but haven't put it on yet because it's not horrendous, but it is noticeable.

 

Sounds like you just don't have your toe fixed then. Camber might eat away 1/32 more than the rest of the tire, but not enough to chew through the tires like you explain.

 

Yeah, camber don't play dat. My S2000 has -3.3 degrees out back. Tire wear is mainly even. If I drive in only a straight line (I took a 4600 mile highway trip) or do burnouts (I...did hella burnouts), I get more of a taper, obviously.
