lowering affecting your pinion angle?

[Stives]

i know lowering would affect your pinion angle but would 2" rear lowering springs affect your pinion angle so much it would bind? and possible brake under stress?

It shouldn't. I've lowered mine quite a bit in the rear and have had no issues. Never hurts to check though.

I will second JRM and say if you are worried about it .... check it. Lowerring WILL change the angle obviously but I don't think a 2" drop is all that radical. Bear in mind too, if you are doing this with coil springs .... a 2" drop coil spring is versus a new factory ride height spring .... your 25 plus y/o car is NOT at factory ride height. A 2" drop spring maybe no more than a 1/2" to 1" drop versus tired old coils. Infact I've seen cars go back UP with all new suspension and lowerring springs.

you make a good point. by any chance would you know what the factory ride height is?

I got a dealer service manual for the 81 probably in there .... if you've ever had a computerized alignment done ... printout usually has spec followed by your actual heights at the 4 corners .... that's usually an eye openner
