I'm wondering if I should use the H-Sport springs with 205/50/15 tires or if I will need to go lower because of the reduced diameter of the 15" tire. There is a 1.2" difference alone between my 205/45/17's and the 15" tires and the H-sport lowers it an inch, so that means I'll have .2" more gap from the wheels to the wheel arch than I have now. I need a good autox setup for STS.

Thanks!

 

I had about a .9" diameter difference and installed H-Sports. Perfect!. You will ride .15" closer to the road but you shouldn't have any problems as I don't. You do have to be careful with speed bumps and parking barriers but you will with any lowering kit. Put a good stiff bar on the back and leave the camber where it is. Makes a big diff on the autox course.
