anyone on here with an 850 with D2 coilovers installed. if so, l want to ask how is the ride quality and are coilovers good on our cars? thank you very much. is 400 a good price for a set of used coilovers together with ipd strut bar a good deal or is it too much?will post pics later. the seller will be emailing some pics soon. any opinion will be appreciated. thank
