Yea I used the rears for a couple events last fall. I put brand new cryo-treared rings on the front hats.BossJockey said:Are those rear rotors used?

cloud9 said:Last night I went out and bed in my pads on the new front rings. I noticed a pretty significant "brake dive" under hard braking. It's similar to what I saw on some of the magazine review videos. I probably didn't notice it as much with the street pads. Man do these DTCs stop the car. I know some were worried that the DTC70 might be too aggressive for the ABS on the fronts, but I didn't kick them off even with street tires. With r-comps they shouldn't be an issue. Anyway, it's got me wondering how the springs will hold up under track conditions ???
Other than the brake cooling kit, did you do any brake mods? DOT 4? Different pads?cloud9 said:Another big factor was the braking points. The braking system worked great. I had a very firm predictable pedal all day. I found I could brake much later than the GT500, but it took me a while to adjust. That's just going to take some time. Ford did a really nice job of giving us a fun car right out of the box
Just a few....he'll be by later to give you the laundry list of brake mods. ;DArizonaGT said:Other than the brake cooling kit, did you do any brake mods? DOT 4? Different pads?
I enjoyed the vids!
Great question Dean. I noticed we must have a 192 stat so my car runs between 188-200 just driving around. One of my biggest gripes with the GT500 was the overheating issue. I ran around 220 all morning. In the afternoon, it got up to 88 degrees ambient (hot for early April!) and temps started to rise. I started hitting mid-230s and eventually over 240 and drew a warning and shut it down. Well I started analyzing my driving and realized I was running way too high RPMs because of the different transmission ratios on the Boss. I typically drove this track in 4th on hte GT500, hitting 5th in the long front straight, and down to 3rd in Turn 15 heading into that straight. I had been running the Boss mostly in 3rd going to 4th in 2nd and 3rd longest straights and 5th in the longest one. That also left me just at the rev limiter in the 4th and 5th longest straights. There wasn't enough time to benefit from upshifting there.Dean#4AI said:Hey Gary, sounds like you had a great time. I can't wait till I get out on track. ;D
What kind of coolant temps did you get? The reason I ask is that my temps are much higher than I thought they would be and that's not even under track conditions.

Well, 4th gear is 1:1 in the GT500 and 3rd gear is 1.69 in the Boss, so I was running effectively two gears down from the GT500! With 5th being 1:1 in the Boss, that wouldn't work since it doesn't have the low end torque like the GT500. So, I let it run in the paddock and the temps came down to 192, but the reservoir was still almost at the top, well above the top of the cold fill line. I went back out and ran 4th (going to 5th in the long straight and 3rd in 15), and temps stayed right around 220. The reservoir was back down to the cold fill line right after exiting thre track. Best of all, I dropped my lap time by over 1 full second. ;D There's just a learning curve with a new car.
The SS lines seemed to make a big difference, but I can't give a direct comparison since I never had it on track with the stock "low compressibility" lines. I can only compare on the street, but the braking was awesome. I have so much time to be gained there, it's just going to take an adjustment from the GT500 braking points. The Super Blue held up well. I'll swap to Brembo next time I change, but go back to super blue for ease of seeing the different color. I never engaged the ABS with the 70s so no worries there. I think you said you had some trouble with those on your GT.ArizonaGT said:Other than the brake cooling kit, did you do any brake mods? DOT 4? Different pads?
Thanks. I have 5 bottles of Brembo left. If the Super Blue seems to handle it I'll try the Type 200 after going Super Blue again.ArizonaGT said:Cool!
Regarding the fluid--ATE also offers "TYP200" which is the same thing as Super Blue, minus the blue dye. Look into this unless you're interested in the Brembo fluid for some specific reason (higher DBP, etc).
