Burned up my brakes at the track, now what?

JARblue · 07-15-2020, 10:26 AM

The Z1 2 pc rotors are too weak for track use. They're cute and lightweight but they don't hold up under real use. This is what my research indicates - I won't be using my Z1 2 pc rotors on the track.

The Racing Brake 2 pc rotors on the other hand are much more solid and do hold up. Rusty, how many times have you had to replace the rotors on them? Ever?

I'd be interested in the comparison of how much track time you can get out of an RB setup vs the equivalent cost of ~5 sets of cryo treated blanks. Not suggesting that money couldn't be put to better use somewhere else. Just pondering.

I've gone through 3 sets of pads without cutting the rotors. The next set, I'll cut the rotors to see what they look like.

What happened to your Z1’s?

Mine were track used. I purchased them before I got serious about my build and was planning mostly street use for them. Figured they would be ok.

But talking to the seller and several others and looking around online, it just seemed like they weren't really up to snuff for track use. So now that I've started building the car for the track, I'm looking at replacing them. It's hard for me to justify anything other than the RB setup.

I also have a set of Z1 two piece lying around. I chose them bc it seemed like folks seemed to use them fine.

I could see how their durability varies based on how hard the are used.

As a relatively notice level guy i cannot imagine i would be beating on them the way a real track junkie would, so i think they're fine

My set up will be:
Z1 2 pc rotors
Endless MX72
Stillen brake ducts
titanium shims
tires undecided (Nexens are out of stock, looking at NT05)
fluid undecided (Endless RF650 or Motul RBF660)

That will probably be more than sufficient for my skill level for now

I was not trying to insinuate that they cannot be used on the track. But I know I am hard on my brakes in general and my comments about the rotors are intended to reflect expectations for myself.

My Z1 2pc were used pretty extensively across several days on Laguna Seca, Buttonwillow, Thunderhill and Autoclub speedway. Only after 2 back to back days at Autoclub roval did they start to deposit so bad they shook the car.

Again, anecdotal but mine have held up ok. I'm pretty hard on my brakes too.
