I've got 2 sets of the gruvenparts rear control arms to fit to the rear. I was going to match the lengths up to the stock ones until I get along for a 4 wheel alignment once I've fitted the ground control mounts and front tubular arms which won't be till after Christmas now. The thing is, my rear tyres are battered on the inside and they're getting noisey. I'll replace them once I have the geo all setup. Has anyone self adjusted their rear camber adjustment? i.e. how much length on the arms adjusts camber by x?
