I went with the Quattro Sport struts an the stock original(85 Ur-Q) springs. The Quattro Sport OEM struts are Boge and are about 20% stiffer Vs the stock Ur-Q struts. They are a good ride/handling comprimise. Got 'em from RD Enterprises: 800.683.2890. Konis would be a better chioce for all-out handling & stifness, but my Ur-Q is a street car. -glen
