I'm planning on machining my rear brake rotor to reduce mass as much as possible. I know rules are different everywhere, but most race organizations I checked with this was acceptable (so far everywhere but AFM).

Is anyone else interested in getting theirs done while I have the machine setup? The cost will be minimal since you can just send me your rotor. Something like this is what I'll be going for to reduce weight:

How much, Jess? Could you do this with the front too? With the lacking surface area, would the bike still scrub speed off as quickly? Design loox awesome.
I'm thinking $20ea for the first round, sound fair?

This is not something you want to do to the front, as it definitely reduces stopping power. It's something a lot of people do to the rear to reduce rotating mass and you can get away with it because you don't need nearly the stopping power on the rear, if you use the rear at all (I don't).

I actually use my rear brake (occasionally) on the track. I've got an odd late entry technique that swings the rear out on certain types of turns. It's allowed me to sneak attack guys on the outside, then cut in behind them just past the apex and pass them on the inside.
$20 sounz awesome, Jess. Please keep us posted on this.
Also, I'm not gonna lie. I've had my share of "agricultural experiences", if y'knowhati'msang, so I DO prefer a functional rear brake. ;-)

It will certainly still be functional, it has to be. But yeah, you just don't need much to lock the rear wheel with your foot, whether you're braking late into a turn, or while offroading between corners :)

These look awesome! Combine this with Mr. Spears rotor bolts and "BAM"!!

Let me check the CMRA rules and if all is good will send mine to you. Please PM address and PayPal info and will get you taken care of.

:DThanks again!

I'm going on a trip from Aug 28-Sept 4th and it doesn't look like I'm going to get these done before I leave, so I'll squeeze it in after between track/race weekends.
