i highly recommend this group buy to anyone considering a coilover upgrade. while the jap spec coilovers i had were fine for flat roads, they werent very good when it came to uneven or bumpy roads. the bilsteins soak up all the bumps and generally make the car a lot easier to drive, i used to have to variate my speed to the road conditions but now i can stick at the same speed no matter what. they handle great too, cornering feels nice and firm, i just need to order the stabiliser bars to finish it off
also gone are all the irritating interior rattles that my old coilovers had
cheers and thanks to Gary, for helping me out with any questions and installation queries i had throughout the process, he's always more than happy to give advice and answer your questions
