I was thinking about doing the same thing. How much camber can you get from stock early upper/lower?

Did I get it right that the 1981 OB's are supposed to have a 21mm spacer on the rear wheels? I changed my rims over to the PD's and there was no spacer there. When I bought the car it had the S4 8" rims in the back. I guess they pulled the spacer when they installed the S4's. The PD's set farther in the wheel well than I would like. So I guess my question is do I need to be looking for 21mm spacers? Anyone have a set of them that they would like to sell? I'm on the road right now and don't have a tape measure to check. What length does a 21mm equate to? 1/2", 1", etc.. Jason

21mm=aprox 4/5". Make sure your studs have not been shortened, do you have open lug nuts?

FlyingDog

21mm spacers were optional up to 84 or 85. IIRC US cars only got them with the S-option. Euro/ROW cars had the spacer as an option separate from the S-option.

No closed.

Then you probably don't have room for a spacer over the studs. You can buy spacers that bolt onto the studs that have their own studs for the wheels. I don't know who sells them.

Here's what they look like, it's mocked up for this picture, no way are these going on that car.
There's some serious brake clearance, about an extra inch compared to me CCWs. They do weigh a ton but otherwise seem kinda nice, they say 'made in Italy' on them.

Hey Mike, would those clear the stock springs?...looks really close the hypercoils..

Mike, are your upper A-arm bushings aluminum?

Mike Simard

Tom, the rim is well clear of the springs, probably 3 inches or so in this case. I don't think that would be an issue with any rim. The springs are actually Pro Shocks 2-1/2s.


'Dog, no the upper arms and every other suspension point has a PTFE lined spherical bearing. Those aluminum bits house a bearing. It probably sounds like overkill to use a spherical bearing when a straight sleeve would do but I'm a believer in them and feel the extra work is worth it. They are self lubricating, trouble free, have zero play and accomodate misalignment, even a supposed straight part like the upper arm has alignment issues. You don't have to worry about thrust too but it is alot of work to assemble them. They have to be perfectly spaced and that takes machining spacers to fit during assembly.

FlyingDog

That is impressive. Good job making the rest of us look lazy.

Those are really nice looking rims. I may try to find them in 8" for the OB before I buy new tires for the 16" PD's.

Also thanks for the info on the spacers. Soon as I get the car back from the body shop I'll get on the spacer issue. Jason

Here's a better price on the spacers on eBay. http://stores.ebay.com/ACCESSORIES-P...ubZ19QQfrsrcZ1
