If you are mainly doing straight line go with the KYB/TEIN. 99% of the coilover setups are way too stiff for straight line. D2's are crappy IMO after replacing 3 sets on different 240s in the last 4 months I wouldn't recommend them. Flysi00 you are the only person I know that likes their D2's, but it also sounds like you just got them. Stick with the Tein setup and you should be more than fine...
