Rear brake pad lifespan

Then I kind of stopped swapping the pads and after mucking up some rotors in the process I realized that I should be swapping rotors also which was alot of work :p

I'm not yet doing the pedal dance but it is something I want to move up to; so far I have only tried it on some autocross runs.

Pedal dance nao.

From everything I've read, same compound front and rear is ideal. Mixing compounds does change braking torque, but will be inconsistent through usage at different heat levels, pedal pressures, etc, so braking balance front and rear isn't exactly balanced and linear.

Are you certain the EBD is actively changing pressures front and rear? I thought line pressures were fixed, and EBD only activated single lines in response to some loss of stability such as an imminent spin, ABS activation, etc (with the VSC on at some level).

If you're threshold braking, it is working.

I meant 16 days on a set of pads.

It really all depends on the driver and conditions. E.g. a more experienced driver on stickier tires on a brake heavy track will go through pads faster.

Eh, I got at least that many and ~26,000 miles out of a set of Carbotechs.. and they still have a ton of life left in the back. I switched to Project Mu 999's just to make F&R the same material.

In my experience, these cars don't use much rear pad with TCS/VSC off.

hmmm... My front DTC-60s will last about 7 or 8 NASA track days. Car has had A/S and summer tires but is otherwise stock. Rears last twice as long.

Still not bad wear, but I've definitely had less overall. I'd guess I could get 20-25 days out of the 999s in the back. How knows on the front, I don't run the front OEM brakes so I have yet to wear a set of front pads, I get bored and want to test a new compound before they are anywhere near dead.
