rear camber on 90 PA?

[Electric_mouse]

what would the camber be on the rear wheels of 90 PA? Just replaced the rear shocks. I have a very slight positive camber at present.

Thanks

Those specs are either in a shop manaua or from an alignment shop, you could try autozone.com, repair guides also.

I believe it should be -1 to -3 degrees, so you need to lean the top of the wheel in towards the car.

That's interesting. I would never have expected that. Have not I tried to contact an alignment shop. Just too busy this week, both at work and home. I did put on about 150 miles this past weekend with no apparent problems.

Here's my plan one I do have the specs.

Weld a 2 foot stub shaft to the center of a disc (good straight cold rolled shaft about an inch in dia.) just larger than the bolt pattern of the wheel. Machine the surface of the disc to make it true with shaft. Drill the disc with three holes to match the bolt pattern so it can be attached to the wheel. I my case with cast aluminum wheels I will also need to make three equal length extensions.

Place the car on a pre-leveled surface, all tire pressures equal and car loaded as normal. Attach the shaft. Using a 2 foot level along the surface of the shaft, a space of .4189 inches is one degree at the end of the level by my calculations. (negative camber would be at the inner end of the level and positive at the outside end).

Basically this is a grand experiment on my part but I believe this method should easily get it in the ball park especially if the tolerance is as much as 1-3 degrees.

Yes, that sounds like a good plan. Just to clarify... I believe negative camber means the top is leaning in and positive camber means the top is leaning out. I would go for -1 degree, personally. As you load the car more, the camber gets more negative.

Yes. That's why I find a negative starting camber surprising. What could be the reasoning behind such engineering?
