I just put my Konis on last week. The Koni has 3 settings for the spring perches; stock, about 6mm lower and about 12 mm lower. I put them on the lowest settings on all 4 corners and the fronts rubbed the tops of the fender liners on the track with stock wheels and stock tire size. Worst part was when I yanked them back out that night to raise them back to stock I noticed there are wiring harnesses that go through the tops of each wheel well. The tires had worn through the fender liner and through the protective tubing of the harnesses on both sides, but hadn't got any of the wires themselves yet. I was lucky.

Everybody with drop springs must run hellacious spring rates or doesn't race the car. I had the fronts shocks full stiff (and it made a BIG difference on the track) and in tight corners the tires would hit the liners even though the front was only dropped about a 1/2". After raising the perches back to stock I had no problems at the autox yesterday and love the improvement and adjustability the Konis give me.

 

Hey DamonB

Are you running stock springs, too?

I had the same problem at Button Willow but I had only worn through the front left liner. I was told that the wiring harness in the front left wheel well is for the airbag sensor and if the wires are exposed they will short and the airbag may go off. I think you should have the harness rewrapped at least.

The Konis height adjustment translates to 2:1 ratio. The height you set on the shock is doubled for the actual ride height.

I had the same problem.
I had to set my Mazda Speed front coilovers at max height and max stiffness to avoid rubbing with 245-45-16's, which are supposedly a little shorter than the stock tires.

 

Yes, I am running stock springs. Do you by chance know the stock rates? Looks to me like the harness in the left side has wiring to the washer and some relays. The airbag sensor is in the right fender; it's the one with the blue jacket (so I am told). I did tape the wires and put new tubing around them.

Oh yeah; the ride height on the Koni is just the perch. By the time you get to the end of the arm and to the wheel it is much more than that. Thanks. I thought the car looked WAY lower than that!
