Convert MS6 Bilstein B6/B8 to Coilovers

I've been running this setup for the better part of 10 years. I'm using Bilstein B6 as the base for my coilover setup and have had them re-valved by FatCat Motorsports. The conversion is super easy - and allows you to run a standard 2.5" ID spring in the front so you can get any spring rate imaginable. The rear springs have some options from QA1 that will serve most people pretty well.

Note: for the B6 vs B8 debate - in this case if you're getting them re-valved for a coilover setup, get the B6's. The longer rods in the B6 offer more droop travel and that's a GOOD thing. There is absolutely no reason to get the B8's.
