Yes it will.

Good, im glad you do or this place would be rather boring wouldn't it. :)

Oh, pppbth. NOT EVEN.

No its not, your not *reciprocating* the calipers and carriers dude. Just
the rotors and they don't weigh much more than the 10.1" rotors. The
weight difference is insignificant.

uh-huh. No. 
86 GTi with a 2.0L crossflow and 11" brakes runs DSP (Yah, I know, he's a
SM car but so what, he's on street tires. and its his first season.) Ive
ridden with him and his biggest problem is tire traction. Typical on any
autox course driving on street tires. His braking is very impressive. as
long as he brakes in a straight line, he's fine and can brake very late.
ANY car that tries to brake as hard as he does with any size brakes not
in a straight line WILL lock up the inside tire. He's got better stopping
power with street tires (??/45R17's) than I do on autox tires. Now, how's
that possible UNLESS the 11's somehow magically perform uh, shall I dare
say.... BETTER? And don't even try and say his tires are better than
autox tires. (I do beat him by 10+ seconds.)

Uh, yah. I always have that problem when im shopping for snow tires.

Novelty? Sure but so are 16V's and I could make many other examples of
what people could call novelty's.  

>Thank you Shawn, I knew you would come through.

Hey, I was just giving my opinion and wasn't backing anybodies position.
Discussing pro's and con's is not just educational, its rewarding.
(Especially when you get these hypertyped replies. Gawd it gives me a
huge grin!)

Oh no you don't. Im not gonna be your next partner. Keep shopping dude!
