Need some good advice

I'm driving a 997.2 GT3 steel brakes, fronts are lasting about 7 to 10 track days (COTA mostly, some MSR Houston and TWS) before cracks are over 10 mm. Using OEM front pads (and pagid yellow rears).

I wonder if Brembo's slotted will last longer. There are two versions, a regular one and an extreme duty (here's the link to suncoast) https://www.suncoastparts.com/produc...2GT3997FR.html

Any advise on what to get. I drive on the streets, not too much (50 boring miles to the office once a week) and a monthly drive with friends along country roads - far from the limit. Try to keep one DE event a month too.

Additional info: typically do at COTA 2:31 to 2:33's on MPSC2 on 50's to 60's (depending on tire condition and track conditions). Also, I don't really push the braking zones as much as I could to give it a better life (most of the times )

I'd really appreciate your advice. Not too worried about noise, but good to have some bite when brakes are not driven at the track already at good working temperature...

I don't do the brake job myself, and have been using the dealer to install Suncoast parts, convenient and not too expensive.

Thanks !!!

Are you looking at/for 1 piece or 2 piece rotors?

AGO

2 piece initially

Might read orthojoe's track thread for another option. He is using AP Racing ones on his 991 GT3.

The two piece slotted rotors should last much longer than your stock ones. You should not experience any difference in braking on the street. You will like the unsprung weight difference.

Thanks for the feedback. What pads are you using or would work well with the Brembos? Any experience with Pagid 19 or 29?

Race Technologies (Brembo owned) RE10 pads.

I'm not a good datapoint for you in that regard as I have a completely different car. FWIW - I was running R19 front R29 rear but now Pagid RS14 all the way round.

Interesting... I'd like to know the reason for the 19 fronts and 29 back... Modulation on brake release? More bite in the rear to induce rotation?

Make sure you're sitting down when you get the price quote for the re10 pads.

It is to shift brake bias as I used to get ice pedal otherwise. I now run a fully programmable Bosch M4 Motorsports ABS, improved brake cooling and the driver learned a thing or two so we were able to go to more aggressive pads.

AGO,
Definitely check out our Essex/AP Racing 2-piece discs. We have a whole bunch of satisfied owners on this forum.

Here's a post I did on the economics of spares, showing how much money our discs can save you in the long run. They perform better, last longer, and have far lower long-term running costs vs. OEM (or anything else for that matter).

You can see the actual product on our site here:
