Track Days with DTC 70's and Pettit BBK

Ordered up some Hawk DTC-70's (front) and DTC-60's (rear) for my Pettit Racing Big Brake Kit, and the stock RX7 rear calipers & rotors.

NO MORE FADE, and quick immediate stopping.

A fellow instructor who has driven my car previously, finally said: "these things finally have brakes worthy of a 150+ MPH [down the front straight] car".

Note: I am using my own fabricated steel adapter plate which not only centers the brake caliper better than Pettit's, but is stronger.

The larger diameter (12-7/8") and thicker (1.5-inch) rotors does wonders.

Thanks for posting your review Neil. I'm going to try these for my next set of pads. I'm hoping they will be a smooth transition from the HT-10's I've been using.

I previously ran HT-10's on stock front brakes, and if I had bigger ***** on the track, I probably wouldn't overheat them.

In fact, I have an unused set of HT-10's for the stock brakes just sitting around now.

The DTC-70's definitely grab faster, so when the say "high torque" braked pad, they mean it.

After two 20-minute sessions I was accustomed to it.

I've got DTC-60s in my stock calipers for this season but so far only run them in the rain so no comment on how good they are when up to operating temps on a dry track yet. Look forward to trying them out in 2 weeks based on your review though

Thinking of giving it a pass this year. Too crowded/hectic I think. Will be at Trackdaze 5/16-17 in a few weeks though. Hoping for some Sun after all this rain

Yeah, I've been running PFC 01's on Porsche Big Red's in the front and the Hawk HT-10's on the 99spec RZ rears and have been happy with them so far. As Gracer said, GooRoo is using them on his big red's as well and has been very happy with them. I'm going to give them a go for my next set. I'll be at the track every weekend starting at the end of May once I'm back from Afghanistan so it shouldn't take me long to use my current ones

Hey Brent, what pads are you running with your LS1-powered FD ? And how do you like them ?

Did you ever run the DTC's ?

Yep, been through several sets of the DTC-60 and 70's. Love Hawk brakes and they take pretty good care of me with all the Time Trial stuff. The 60's seem to work better on my car than the 70's. DTC60 fronts and HT-10's in the rear are a really good combo. I currently running DTC60's on all 4 corners and working on getting my proportioning adjusted via my balance bar and seeing if I see any improvement.

If you are a NASA instructor, contact Jay Andrew at Andrew Racing. He is really good to us. Shoot me a PM for details. Hope all is well.

Brent

I'm a big fan of the DTC-70 pads. Last weekend I raced with some pagid 14's. Good firm pedal but not much feel. When their done I'll go back to the DTC.

I agree, Pettit BBK with the dtc 70 is a really great set up. I ran the 70 on both ends of the car using a wilwood NDL caliper and rz rotor. I've also got a bias valve that let me dial in a great balanced set up.

BTW, ahem, my Pettit kit is for sale in the classifieds with mega spares including a couple of sets of dtc 70 pads. A great deal for someone.
