GTO guys, help needed.

[Rodeheavers]

I have a customers car at the shop that has bad raer camber, The car has lowering springs and i cant seem to find an answer on how to adjust the rear camber... I tryed adjusting it myself with no luck... help!

[Red]

what degree is it at?

Mater will know how to set the camber.

This might help, its a post from ls1gto.com

The gto uses a semitrailing arm rear supension, the same set up as a bmw 3 series, 92-05. I would guess camber is adjustable just like it is on bmw. Bmw does not use accentric bolts to adjust camber on the rear of the 3 series. The 3 bolts at the front of the trailing arm on the 3 series have a sloted plate they ride in. Meaning you loosen the front mounting bolts and then push the trailing arm out or pull it in. My guess is the gto should be very similar to this if it is adjustable. When i get a chance i will take a look at mine and see if its the same but that won't be for a few days.

Sorry, I was out of the country.

If you still have the car, Pedders sells rear eccentric camber adjustable bushings. I have them on my car. I have tons of negative camber dialed in at all four corners for autocross purposes, but with the aftermarket eccentrics, you should be able to get things set up well.

What lowering springs is the car running? King, Lovells, and Pedders are the 3 most common, reliable brands. The problem with the GTO suspension is that since it's IRS, when you launch the car, it causes even more negative camber. Severe inside tire wear is a common problem on GTO's that still have the factory, sagging rear springs. When I took my stock springs out, with 8,000 miles on them, the rear of my car was squatting 1" lower than spec. The problem is that the factory springs were a very soft spring rate, combined with strapping the cars down too tight on the boat ride over from Australia, which caused premature wear of the springs.

Hope that helps.

thanks for the help bro.
I installed eibach lowering springs in the car about 2 years ago and i think they have sagged as much as the are able to sag!!! THe car is low, very low. THe tires are up in the fenders. We have installed the LCA eccentric bushings and cant get anymore adjustment out of them... I just dont know what to do with this car. I cant remember the brand of camber bushing we used, but maybe i should try getting a set of the peddlers and goig from there...

Yeah, I realize Eibach is a great company, but I've read on more than one occasion where people have had issues with their springs for the GTO. I think it's just because the car is on the heavier side. lol.

I wish I could help out, I had a set of 1/2" Pedders drop springs that gave a very nice stance, but I sold them to someone else when I stepped up to the adjustable coilovers.

There can sometimes be a wait time of a few weeks to get Pedders parts, since they have to come from Australia, but they've recently become a GMPP vendor, so maybe things will start to ship more quickly.

Just keep an eye on the Pedders or whatever brand camber adjustable eccentrics... they all tend to loosen over time.

My 1/2 drop springs show terrible inside wear on my rear tires... I am going back to 5/16" raise drag springs as I never had a problem with them in the car.
