respeed race coilovers on the front, spring perch welded at 6" from top of the strut tube.
respeed camber plates
technotoytuning roll center adjusters to correct the front suspension.
375 spring rate on the front, 200 on the rear
respeed coils for the rear and i took the height adjusters out so its just the springs
15x8" diamond racing wheels with a 4.5" backspace (or for those who like the offset measurement its 0 offset)
i have 175/55r15 tires all around and no rubbing what so ever.
i rolled my fenders with a baseball bat and a heat gun and had no issues.

when i get some more pics i'll post them..

also i know there is going to be alot of hate on my stretched tires but i make sure that my tire pressure is constant and i do not race my car either.

One thing I question is wouldn't 4.5" backspace on an 8" wide wheels be about a +12 offset?

.5" = 12.7mm (4" would be center of wheel)


I think a 4" backspace on 8" wide wheel would be a zero offet. That's the way I read offsets anyways, just wanted to comment on that incase someone is trying to copy your set up based on offset. someone chime in here

How much research did you do on tire size? With the coilovers are you certain that the widest you can go is a 175 before you would have rubbing issues?

im trying to go for a flush look but nothing too close to the fenders so i can use em for auto X. basically im looking to roll fenders to make enough room for suspension travel wihout looking sunken into the wheel wells.

thanks in advance :]
