I have a set of Koni SPSS3's that came as extras on a recent car purchase and I have no use for them but a friend can use them. I dont want to rip him off and at the same time I have no idea what they are worth. I know they are over a grand new though. The previous owner said he had them checked at a national event and the dyno curves looked great, and that he'd run them on his car with no hesitation if he needed to. They are complete units with GC sleeves and 450/550# Eibach springs.

Thanks
