Hey all,
Has anyone ever experienced rubbing with a stock suspension? All I have are Koni Yellows on the highest perch. I normally run them full soft in front and back. A small outside corner of the left front wheel liner is worn through and has exposed a portion of the wiring. Any ideas about how to fix this? I run fairly high tire pressure, 38lbs, on 225/50s (stock) and on stock wheels. Could it be the high pressure is creating too much center bulge? Or perhaps I should stiffen up the shocks? I'm mainly concerned with the two exposed wires shorting themselves out right now but I also want to fix the problem. Would covering the spot with electrical tape be sufficient?I do make some pretty hard mountain runs but I would think even with the wheels hitting the bump stops the car should be designed to not be able to make contact with anything in stock form. Is this untrue?

you might need to adjust the shocks to a firmer setting...are you sure you're running the highest ride height on the shock? Maybe you've got the perch settings reversed, and you're really running on the lowest ride height setting? yes 38 lbs cold pressure is too high. 38 lbs hot pressure is probably ok, but I'd knock it down to 35 lbs warm pressure. try covering the worn spot on the fender liner with a few layers of black racer's tape. that will at least keep the wires from being too exposed...your 225/50-16s might be taller than usual. each tire manufacturer has a slightly different dimension, eventhough the size is supposed to be the same...

Check your front sway bar mounts. They could be broke and causing excessive roll in the front.

when are you rubbing, under corning, when you hit bumps, some other time?

Like lenny said, you might look at the sway bars & mounts if it's under cornering.

As far as no possible rubbing with stock suspension - that's not entirely true. That may have been the idea, but after speaking with a mechanic in my area, it's just not the case. The mechanic (rotary specialist) takes cars for a road test after he finishes them to make sure they're in order. He says that there's a 180 degree on-ramp with a dip in the middle that about 1/2 of the 3rd gens rub over when he hits it at high speed.

Now that I have P-Zeros on my car, I rub when I go through a corner at high speed due to the increased grip and therefore more suspension compression. I've got Eibachs on stock struts.

I haven't been able to determine if the rubbing occurs under hard cornering or going over bumps. Stiffening the shocks would help with the bumps, but maybe its a combination of hitting small bumps while cornering. As for the shocks, I'm 90% sure I have them on the high setting. They are set from the factory to be at the highest setting (which is identical to stock) and I didn't change them, although I don't remember where they were, I just remember thinking, yeah, this is the high setting cause the shock goes like this etc... I guess to experiment I'll put some tape over the spot and go for a hard run with the shocks stiffer and some air let out of the tires and see if it rubs it. Maybe an upgrade to stiffer sway bars is in order. The only excuse I can think of is that at the softest setting, Konis are actually softer than even the stock touring shocks at CERTAIN dampening speeds. So maybe thats a factor. A stiffer settings they are almost identical to the R1 shocks, I have the dampening graphs in my computer if anyone wants them.

Anytime I would go up Glendora mountain road with my stock suspension setup, I would scrape (actually hear it)the plastic linings...I think its just part of the stock setup, with the designers not giving quite enough clearance. I have since lowered the car with some Eibachs, and surprisingly it has not gotten worse (of course not better either)....I havent checked my sway bar bushings recently though.....

Hehe ok then maybe thats just the way it is. Lately I've noticed a lot of people know about GMR outside of Glendora, which is weird since 99% of the people in the LA area don't even know where Glendora is. Its nice having such a sweet road outside of police juristiction just a mile or so away .

No doubt, GMR is a blast.

Ok update, I was taping up the spot in the fenderwell and I noticed that the left side sits a little lower than the right side. Probably 3/8"-1/2". Has anyone had this happen before?
