Boxster brake performance on early 911

Anyone have experience w/ boxster brakes on a 911. How is the performance?

Garner:

For street use only, its a nice upgrade.

For any track use, its a failure. There are FAR better solutions depending on your wheel diameters.

15" HREs for street
15" fuchs for track

Suggsetions????

If you are going to do track events you need BRAKES and the only effective brakes for 15" wheels are a 930 Turbo brake conversion.

They REALLY work well,...

Which 930?

The early turbos used S-calipers right?

Didn't the 78/79 turbos use a version of 917 brakes?

Why do you say the boxster brakes are no good for track use? Cross drilled and vented rotors, stiffer, lighter calipers. I would think thats a darn good start. 930 brakes are not that cheap.

Yes, thru '77 930 used S calipers front A calipers rear and std. rotors. Theses are fine for 2000#/200hp cars. Steve is referring to the '78 - 89 930 calipers and rear rotors and a custom front rotor setup.

From Steve's site, these are 930 brakes, the minimum to have on heavier faster cars.
