Front tires hitting ground effects in turns

Anyone have or had this problem? Its a 92 Camaro RS. I rebuilt the entire front suspension. With moog front end kit, spohn tublar a arms, spohn wonder bar, kyb struts and strut bearing plates, suspention techniques sway bar, moog z28 replacemnet springs and the big brake upgrade LS1 front brake kit. I also ut a new quick ratio steering box in. I got everything together and I got it as close as I could to the settings of the old stuff. Obivously I still need to get it aligned. I took it for a quick right around the block to make sure everything was working when I heard a scrubbing noise in turns. I went back home and saw that the outside egde of the tires were touching the rocker panel ground effect on both the driver and passenger side when turn the wheel all the way. I tried adjusting the sturt plate a little and I do have a set of Z06 wheels (that I was saving to put on after the car was painted), I put them on with the spacers and they did the same thing. Thanks in advance for any help.

i had this same issue after i redid the supension. what it is with bigger tires and new supension it sits to high and it hits the gtound effects. let the supension settle and it should clear up. i ended up lowering the car and i dont have the issue anymore. give it alittle time for the supension to settle and it should be ok

Still have same problem after getting it aligned. A little better though. I cant figure it out. I was also thinking of getting a aftermarket K-member.

tires rubbing

You didn't post the tire size, but the STOCK TIRES on these rubbed. 245/50/16 was just too big for the fronts. I ran 225 up front and 245 in rear. There just isn't enough clearance for the stock tire size.

Doesn't the steering box used on cars with 16" wheels from the factory have different bump stops?Is this the style box you used?And like IROCINCO stated you didn't post tire size - seems GM designed it for the Goodyear 245/50-16 becuase if you notice tire height varies between manuf in the SAME size tire.

Since the car is an RS the stock size that came with my car is 235/55 16. Thats whats on the car now. I also have a set of ZO6 Wheels that have 275/40 17. They do the same as well. Ive seen others on this board have Z06 wheels as well on there thirdgens. I have a stock steering box for a z28 that is a quick steer 2 to 2 1/2 turns.

I wish I could help. But I have a similar issue. I am running quite a different set up though.

I have an aftermarket manual box, with 275s up front and PA racing arms, and K-member.

I rubbed it once, but that was with the fenders not fully attached and I never found out where I was rubbing. If I figure out my issues I will let ya know how I did.

Good luck with your problem.

Ok thanks. I was also thinking of replacing my stock strut plates with these to see if that would help any.

Make sure you don't have the rear wheels on the front, and the front wheels on the rear! The 16 inch wheels are designed differently front to rear - the rears will not swap with the fronts. They are marked inside the rim.

Just find where it rubs and trim up the ground effects, it's not that hard. My brother is clearing a set of 17x9.5 Z06 rims and 285/40's with nothing more than triming 1/4" off the inner edge of the front ground effects.

The 12" brakes you put on offset the wheels out a bit farther than the stock 10.5" rotors. Thats probably the root of your problem.

Just change your front spacers for your Z06 wheel from 2" to 1.75" if that what they are.

I did a little trimming of the ground effects and that helped. I have to do some more and push the fender well cover back a little at the bottom, but I also have a problem of the inner edge of the tire rubbing the sway bar when the wheel is turned to the stop ( it starts hitting right before you get to the stop). Since the spohn a arm have no steering stops, I can weld a small stop on but I not sure what that will do to my turning radius. I contacted Spohn about this problem and he was not able to help me, I also asked about steering stops on the a arms and he basicaly told me his competitors dont use stops, so he dosnt use them.

Had the same problem.What i did after i installed the spohn A-arms.Since they have no stops like the stock units.I made some from scrap metal & welded them on.There is nothing to stop you from "over steering".Without them your steering knuckles will touch the A-arms.Which results in your tires turning in too far.The stops didnt eliminate the problem, but it was there with the factory A-arms anyway.Though now its about the same as before.Plus im running 255/50-16 tires.Mine also rub on the sway bar,bracket on the front frame to batt tray/fender support(both sides) & also on the plastic mud/dirt gaurds just inside the fenders!All these were present prior to running the larger tires & spohns.

i dont have ground effects so i never did hit them but i did rub the swaybar with only 17x8's on 4.5" bs and 245/45-17's.. i run stock s-10 extreme wheels and tires.. 16x8's, 4" bs, and 235/55-16's.. a much better ride compared to the 17's and they dont rub the swaybar anymore.. but they do occationally rub the inner fender plastic..

I was just looking at my car and Comparing the ground effects to the 85-90 style and the 91-92 style which I have go into the wheels well when the older style does not. I have to file the ground effects down a little more and that problem will be fixed. The wheels will still rub a little on the plastic fender well but thats no big deal. As far as the sway bar goes I will mess around with a small stop on the a arms and see if that gets better.

Having steering stops is not going to reduce your turning radius. If you wheels are hitting the sway bar now it's not like they can turn any further. I would fab up some stops and just trim them untill you fix your rub on your sway bar.

Yeah I was thinking of making an adjustable stop that can be turned in or out. Like maybe welding a nut to the a arm and turning a bolt in or out to adjust the stop.
