what's a fair price for barely used (<500mi) stock springs and rear cambers from a mazdaspeed3?

 

well the Eibach springs are around $250-$300.
and the camber links are around $100-$150

 

Not sure what kind of market there is to sell stock parts.....I would think pricing would be significantly lower than aftermarket parts.

I'd keep them for when you sell the car, that way if the person looking at the car doesn't like the ride height, you can tell them you have all the parts to return it back to stock. (recently did that with my 3 that I sold a few weeks back.)

 

find a local mazdaclub, if u can. or at least try Mazda3forums.com

IIRC, the stock mazdaspeed springs are stiffer, and offer a slight drop.
