Reply to "Rear Suspension Rebuild"

Swen,

The spherical sway bar mounts are a must have.

If you want to preserve the road islation of your suspension I advise installation of new oem style rubber bushings. I understand this is expensive and that's why most people opt for poly bushings, but poly transmits both road noise and road surface (harshness) into the chassis. Especially sharp edged bumps, that sort of thing.

I'm no expert on the springs, but 450/550 sounds about right. With modern gas shocks the ride will end up being quite compliant. The 350/600 you have now soundslike your ride is currently imbalanced, stiff in the rear, soft up front.

I would rebuild the rear spindles (stub axle bearings?) if they've never been done and there's money in the budget OR if they show signs of needing it. It's expensive, but a set of billet axles are very well worth the money in correcting the Panteras rear bearing problem and insuring nothing is going to break on the track.

If you're not referring to the rear axle bearings but rather to the lower pivot of the rear upright, if it's oem, it will probably need replacement.

You need adjustable upper rear control arms only if the camber adjustment is way off, it will depend upon the condition of your chassis back there. An adjustable spreader bar may be adequate. I say wait until the wide tires are on & the alignment is checked before you spend the money. No rush to do it all at once is there?
