^ After this weekend your not going to have Stoptechs. I am. You said mod swap, right?

Also, are you going to run at Road Atlanta at the end of this month?

No Road Atlanta this month. I've spent too much on track days this summer.

Doing Zcon wednesday
Roebling Road the weekend of 20 August
VIR Sept 9-11
Road Atlanta November
and thats about it for now. Probably one event in October too.

OP, did you properly bed your pads before the event?

I assume you believe the rotors are warped because they shudder when you brake? Do they shudder when your brakes are cold?

If you answered yes to the first and no to the second then you have something called "brake judder". Good news, because your rotors are fine. You just need to remove the uneven pad deposits from the rotor. This can be done by machining them or sanding them with garnet sand paper.

If you go the garnet route, you will need to order it over the internet. It is almost impossible to find any non aluminum oxide sandpaper in stores.

Took the nose off and stared at how hoses would run to the sides of the fender well………….I really didn't see much room for hoses so I'm opting for another brake cooling approach. I'm going to mount flaps to the front stabilizer bar that will direct air flow to the rotors. I'm machining a black Delrin frame that will cause a curve in some toughened/semi hard rubber. When I'm done I'll shoot pictures.
