Foxey Bobs Racing

GW: We were using hawk dtc-30’s on DBA standard slotted rotors.  The setup worked well, and I never seemed to have issue with any sorts of fade.  All in all they seemed to be working out well.  I did manage to somehow manage to turn the lettering on the right front caliper black, and started browning it, the drivers side though not so much.  After the weekend the pads were pulled, and it was obvious they were getting VERY hot as there was melted pad/backing plate or some material melted all over the stock shims (this was only in front) but the pads themselves looked ok, so they were retained for the time being.

BIR- For BIR the same pads and rotors were used (DTC-30’s and DBA Standard Slotted).  Obviously a fluid bleed, but since there was no issue at Gateway, a full flush was not performed.  New, titanium backing plates were added with the pads to try to help save the calipers a little.  With the new tires, it was unsure of how the brakes would hold up, but again they performed well.  A pretty sizable shimmy in the right front system developed and was getting pretty severe by the end of the weekend.  While I can’t say that they worked flawlessly, I can say I wasn’t disappointed at any time, and they did hold up to what was turning into some pretty good abuse.

BHF – Before Blackhawk it was decided to go with a different pad that should be able to handle the extreme heat these brakes were producing.  Hawk DTC-70’s were chosen for the front and rear.  At the same time some new brake cooling ducts were added.  As time was short, it was decided to go with Quantum Motorsports premade ducts that simply mounted to the hub with an outlet sitting right over the ABS sensor, and directly into the middle of the rotor.  There was some criticism of the Quantum part before I ordered, but it was chosen for a few different reasons:

1) It was made of metal, not carbon fiber.  Obviously carbon fiber is a great option around hot parts, but it also made us nervous as that wheel well isn’t the safest of places, and durability was deemed more important in this case than weight.

2) Cost – the cost of the QM part was about 25% that of the “premium” option, which is money going a long way towards other parts.

3) The QM piece covered the tie rod ball joint, so protection for that was maintained while being able to remove the dust shield for extra cooling.

4) And finally – it was nice having the abs sensor cooled as well, as we have heard stories from our Evo friends (evo being such a similar car, we feel a comparison can be made) of melting, and actually SETTING on FIRE the abs lines because of such extreme heat!

Hose routing to the front of the car, and making sure there was no rubbing was a bit of a job, and it was thought the only way to get it done was to remove the ladder brace under the car.  In the end it was maintained, but over the course of the sessions at BHF very, very small holes were rubbed into the lowest point of the hoses.  It was strange as they weren’t even holes, but looked like they were just cut on the supporting rib of the tube.  It really didn’t look as it would affect the overall flow much, if at all.  With the new suspension, it is still in the air about what the fix is, but eventually the solution is a new sub-frame.

Typical brake fluid bleed, and again didn’t flush as the fluid was still newish and no boiling issues were experienced.
