I don't have a family, I just enjoy having a spacious car to haul all the stuff I buy. I realize that PM will add considerable amount of vibration. But my goal is to build basically a mild track day 6 seater to weird out all the RX-7 and Miata guys on track day at Laguna Seca and Infineon Raceway.
I will be running on stock wheels with bilstein B6 HD on stock springs. Mazdaspeed 3 Oem rear sway bar, moog end links. Goodridge stainless steel brakelines. I also have a cosworth BSD balance shaft delete kit but I holding off on putting it on until I put my PM on, since I don't know how bad vibrations will get. If vibrations are not too bad I will put on the BSD and order up a oil pan baffle for it. At this points all parts are in except for the Bilstein which will be ordered up soon. I looked through all the suspension kit and coilover options but found nothing to my likings.
Are there B6 for our M5s? Looking at Bilstein's website I'm only able to find B4s.
