I don't think that enough good has been said of the standard brakes. I love their linearity and feel on the street. And I was also impressed to see that the Bondurant Trackside cars have standard brakes. We were asked by the instructor to avoid holding the brakes on hot rotors when stopped (to avoid warping), but there were no issues with fade or smell at any point during our day-long class. Granted, most exercises were short, and only once did we run without stopping for more than 20 minutes, or so, but the brakes remained strong.
How did the brakes feel during your chase of the X1/9?
The standard brakes are quite good, and certainly just fine for street and light track duty. Improved fluid and pads will make them even better for track action. Now if I was going to run a 20 min session at a fast track, and really wanted some fast lap times I would switch out for Wilwoods. Short of that, I think I would keep the stock brakes and maybe upgrade the pads.
Resurrecting an old post with a question that likely proves there are stupid questions:
What really is "light track duty"?
A- Your frequency in going to the track
B- How long each session on track lasts, and how many sessions in a track event
C- Whether you're constantly going for your PB LT OTT, or, you're driving around the track for sheer giggles and fun and wind in the hair helmet with no worries about The Man ticketing you and you are unconcerned with times because obsession can suck all the fun right out of things if you engage with it
D- B and C
E- A and B
F- A and C
G- A B and C
H- Varying degrees and permutations of any/all of the above and didn't you just hate those D, E, F, G and H multi-option options in Uni?
