I have a set of springs recently removed from my 86 Coupe GT.
Their "lowering" springs which stiffen things up a bit,
improve handling considerably, and lower the car about 1 inch.
They'll fit all years of the Coupe GT's and 4k's (non Quattro)
First $75+shipping gets them.
(Or possible trades!!!)
Their in good shape, nothing wrong.
Recent "coil-over" setup forces sale.
