Title: monster brake upgrade weight comparison Post by: BK_856er on November 08, 2008, 08:32:28 PM Just for giggles I weighed my old/new rotors + calipers (both sides combined) on a digital bathroom scale:
- 300mm rotors + 2-piston floating calipers (OE on the M695 and S2R800) = 10.5 lbs. - 320mm Brembo narrow-band rotors + 4-piston/pad calipers (similar to xx9 SBK) = 9.5 lbs. Not too shabby. No unsprung weight penalty! BK Title: Re: monster brake upgrade weight comparison Post by: DucSteve on November 08, 2008, 11:09:45 PM Only con is a lighter wallet. Oh hey, that's even less weight...

Could be. I was happy to find that the whole change resulted in less unsprung weight as opposed to more. I couldn't get accurate weights of the individual components due to the limitations of my scale, but the 320mm rotors felt noticeably lighter than the 300mm ones, so it might be a wash in terms of the new larger diameter since most of the weight reduction seemed to come from the rotors anyway. My main objective was improved braking, which should now be in abundance!
