We're about 10 to 1 on people going with a 15mm front and 20mm rear, but we've definitely had guys mix it up and be happy. It's a little bit about personal taste at that point.

We've had a customer nice enough to send us his DIY on the stud replacements, it's the perfect saturday afternoon project if you have basic tools.

DRS are less expensive than the DRM. I'll PM you the pricing.
