I had a friend with a TT capri.
We fitted this with bilsteins and springs from AVO worked awesomely well.
At the rear we used a uprated leaf spring from I think PETER LLOYD, with one of his exhausts as well, sounded gorgeous it did.
We also later fitted a location kit for the rear axle as they like going for walks!
I can't remember if it was his car or my old car to which we fitted an anti dive kit, which also seemed to sharpen up the handling too.
There is a place in KENT(?) called TICKOVER that do capris and are very good with all aspects of them.
