Making the best of the OEM Brembo's for track?

PF 2-piece rotors here, Castrol SRF fluid and Hawk DTC-60/70 pads with ducting and titanium shims. About 350 whp. I don’t bleed the fluid all season and after I change it. Have never boiled the SRF. Rotors last 20+ days. Pads last around 4-5 days before they are getting low. I don’t like to run them down to the backing plates. Not worth the worry to me of running out of brakes, plus the heat transfer to the fluid will be more as the pads get thin. I’m planning to try the ST43 pads since I’ve heard so many good things about their longevity.

I'm on DTC 70s right now as well, Centric high carbon blanks (until I can free up some cash to replace my DBA 5000 rings), Motul RBF600, Ti shims, 2" ducts. I really like how the 70s feel but I'm not a fan of how expensive they are and how corrosive their dust is, They pretty much destroyed the finish on one of my sets of wheels. I've got a set of Carbotech XP10/8 that's going on after the Hawks are done but after I'm through the Carbotechs I think I'm going to give the ST43 a try as well.

Carbotech makes an excellent pad, I just can't afford them. LOL. They wear well (and the they tend to wear at the pad, as opposed to the rotor) and don't seem to dust much. What dust there is seems to corrode less than most pads.
This is all based on a friend that used them, exclusively, for a number of years. I've heard nothing but excellent things about them.
If I had the cash, I'd be running them.

Sounds like you are still HPDEing so the brembos will be just fine. For now it sounds like you need a good pad, better fluid and rotors. Long term when you stop riding the brakes so much (I still do it too 
) you'll want to look into the ti shims, air guides/ducts and other tricks to help with the heat.

The ST43's and ST47's are the best pads I have ever used in my 15+ years of tracking.
I currently use ST47 front and ST43's rear. The ST47's are by far the best pads I have used and they last forever (just like the 43's)
I've used the rear 43's for about six events now and they still look brand new. They barely show any wear.
FYI, the ST43's in the rear are LOUD AS HELL. I can drive the car to events with the ST47's installed up front with no noise but I have to swap the rear 43's in at track or I go crazy to/from the event.
Here are what my 43's in the rear sound like on track:

I wanted to wait longer before moving to an adjustable suspension but we are for the second time having to pull the front upper spring cap to weld since it's cracking AGAIN so we figured it's maybe time to upgrade.

U definitely shouldn't have to bleed your brakes that often, that's cray.
I use to use ST43's but I switched to DTC60's (with Hawk HP+ out back) and prefer them now. You can modulate the ST's more, but the initial bite of the Hawks is superior IMO. I use Centric high-carbons and AMSoil DOT4 with Ti shims (a must), and I've never boiled my fluid. Pads faded at Pocono once, but it was a weird layout where they went from dead cold to torturing them the second half of the lap. 300whp/3300lbs

Side note, what are you using for data acq? I really like how it's formatted in that video.

I barely use the brakes on the street with the DTCs since the pads sound like concrete against the rotors when cold. I approach stops slowly to minimize the damage until I get to the track. Between track events I put on more street-friendly pads (DS2500s).

I just read on Racingbrake's site that they recommends not using shims with the SS pistons (not needed). So you may be able to get by without.
Our pistons also have vents to further prevent heat transfer to fluid, allow you to run your brake system at lower temperature which means less replacement on brake fluid, and eliminate the use of titanium shims saving you down time, operating and maintenance cost.
If you are hard on brake and have been looking to improve your overall braking efficiency, and tired of replacing brake fluid and don't like the soft pedal due to the use of heat shield Titanium shims, look no more!
