I got my MM front and rear C/O's in the mail the other day. I kept telling myself that I was going to wait to install but I just couldn't. I installed the rears since they would be the easiest. The fronts will have to be this coming weekend or later. I've had to take it easy since the rear wheel rate is slightly higher than the front. I don't want to pull any Formula D on the morning commute. Either way they seem to have improved the ride. I went from a 350# conventional springs to a 250# coil over spring. The rear seems more planted and they weren't too noisy today on the drive to and from work.
