I run ASP in auto x. Stock size brake rotors, ebc pads. I want to do open track days. Only 1 FD. my question is can I upgrade to the larger 99 spec brakes and still run in ASP? Can I run anything 99 spec and still be in ASP? Where are the rules that govern upgrading to newer model year equipment? It's not like I can realistically run a 99+ FD here.

 

Usually you can update and backdate parts on cars that are listed together in the rules. For example 86-91 cars are considered pretty much the same car in most classes. Your problem will be the fact that the cars weren't sold here that year so the SCCA will probably not have them classified with the other FD's.
My guess is no.

 

Is there a way for me to submit something so that I can do this? Certainly there has to be some rich ****** auto xing a skyline or something somewhere.

 

Don't forget ventillated brakes for teh utlra-cooling.

 

Since you are running ASP you are running stock power levels. The brakes on an FD are really pretty good. I would recommend getting some good track pads, fresh brake fluid and giving it a go. I know plenty of people (myself) included who have never had problems on the stock units (as long as you have fully flushed the brake system and are using good high-temp pads).

And no, you are not allowed to backdate your FD using 96+ parts. The class is specifically for 93-95 FDs.

 

I've just heard horror stories of stock rotors cracking since they're not big enough. I figured the extra space on the rotor on the 99s would hold up better.

 

All the stories that I have heard of rotors cracking involved cross-drilled POS rotors like the Brembo's. These units are for looks only and have no place on a track. The stock rotors are fine. The guys who are needing to run the big brake kits are those putting out a lot more HP that you will be.

Again, use good pads and fresh fluid. You will overdrive your tires long before you overdrive your brakes.

More specifically use a racing brake fluid for track days if you can. I prefer Motul for the race car but it absorbs so much moisture it needs to be bled a lot. It would be fine on the street but you need to run new fluid into the system before every track event.

 

ATE superblue has been holding up well to auto x compared to old DOT3. I'll try that and see how it holds up on the track.

 

I never had problems with my stock rotors cracking. The stock brakes (with proper pads and fluid) work fine at most tracks. Only when running R compound tires on tracks known to be very demanding of brakes (like Laguna Seca) did I have serious fade problems.

 

I can't imagine needing bigger brakes for Auto-x. Just get some pads that have very high cold bite and you'll be fine. Be aware however that such pads will fail in spectacular fashion if you try to take them to a road course.

 

I've never had problems with stock rotors on the track either, and I'm on R compounds. Just get some good pads and fluid(which you have).
