Does anyone know if you can run non-sport calipers with the sport rotors, brackets and master/booster?

The NB2 I bought to replace my NA8 ended up having sport brakes. While this is good on paper it completely ***** up my spares collection. The rotors from the NA8 are pretty much toast anyway so I don't mind finding a new home for the ~$75 in new rotors I have laying around the garage, but getting rid of the 2 pairs of front pads and 1 pair of rear pads is painful.

I had no brake problems with my VVT swapped NA8 so I don't really feel the need to upgrade the brakes to the sport brakes based on performance. And this new car will be making less power than the old one since I'm building it for PTE instead of CSP.

So yeah, sport master/booster + sport rotors + sport brackets + non-sport capilers, total fail or minor bump from non-sport brakes?

Also, anyone know if this will be 0-points with NASA on a 2001? I'm same line as 2003+ cars so sport brakes can be considered BTM. If I choose sport brake BTM do I need to do the entire brake system or can I piecemeal it as long as it is completely stock components assembled without modification?

Guess I should have made sure sport calipers work with non-sport brackets before posting this terrible thread.

Standard rear calipers work with the rear sport brake brackets.

From what I understand, Sport brakes on an '01 or '02 are no points because they were BTM on '03 and '01 to '05 are a single group.
Last year they were no points on '99-00 too. But because of the split of '99-00 from '01-05, they are no longer.
No idea on the mix-n-match. I have a full '03 setup, calipers, brackets, master, booster and prop valve in boxes. For once procrastination turned out good, I waited until after the rules came out before planning to install them.

As far as PTE goes, if you're classing as an '01+ chassis, Sport brakes are a 0pt mod. You technically can't mix-and-match the caliper and bracket - it needs to be the entire assembly, and Greg defines "assembly" as an entire axle (front/rear) of parts. IOW, you can mix-and-match 1.8 rears and Sport fronts or vice versa, but you can't use 1.8L rear calipers in Sport brackets. Master cylinder and booster are open for all cars, so it doesn't matter what you have there.

from my understanding you can't use the front sport brackets with 1.8L calipers. Something doesn't fit, I can't remember.

If you are asking if you can use sport calipers and 1.8 bracket, I would assume that won't fit either, but I dunno.

(if you decided to stay with the sports) Depending on your pad type, I would be willing to pick up the rear set and possible one of the front sets shoot me a message sometime.

Front calipers and brackets don't mix and match between 1.8 and Sport. Rears do, I believe.

Using non-sports fronts and sport rears would need a prop valve to tune to an acceptable balance, correct?

You always need a prop valve. Stock cars need a prop valve.

FatKao

7 weeks till the first event, cage builder needs at least 3 of them. Gotta prioritize.

Prop valve install takes 30 minutes, less if you're combining it with a caliper swap as you only have to bleed the system once. Prioritize better

I did my prop valve and master cylinder in 30 minutes tops...then spent like 2 hours adjusting the brake pedal because I couldn't break the booster's pushrod free.
