I too signed up for the AP Racing / Stillen GT brake upgrade evaluation program. I decided to go with the Solid Slotted Rotors. Stillen Recommends the solid rotors on the rear for maximum braking performance.
I plan to attend a few more tracks days this year. The solid rotors should provide the best performance and eliminate the potential of a cracked rotor which drilled rotors can exhibit with heavy use and extreme heat cycles.
I want to thank Bill / Shadowman for his informative write up on Ed's car. Because the system I have is slightly different I wanted to make a separate post. Being a recipient of and early kit I too had to make the slight modification to the kit and car. I want to thank Bill for the pre-warning on slight mods. I too had to trim the front caliper bolts. Drill out the rear spacers , grind off some material on the rear of the e brake mounting ears. I also reused the stock front brake hoses on the rear. The kit comes with new front brake hoses.
By rotating in the E-brake caliper piston I was able to get enough slack in the system. I did not need to make any adjustments inside the car to the E-brake handle or cable.
Kyle from Stillen has stated that the new kits come with the proper bolts. and they have modified the E-brake bracket so no grinding should be required. They have also changed the bore size on the rear spacers so these minor issues should be gone for any future users.
The weights of the AP Racing Slotted rotors seem to be equal to what Bill reported for the AP Racing drilled Rotors. I recorded 20 lbs for the Front rotors and 22.5 lbs for the Rear rotors
The mechanical work is very straight forward and not that difficult to perform. I really enjoy working on the GT so this was a fun Project for me.
I did a complete Brake fluid evac and refilled with ATE Super Blue Brake fluid. I have a large vacuum pump and I attached a smaller collecting bottle in line ahead of the pump to monitor the bleeding fluid. This system worked very well.
We have had a lot of rain so my driving time has been limited . I have just started the bedding process so I cannot give you any feed back on extreme performance yet. Initial feel is very good.
I would like to note. The Clearance of the front rotors to the wheel is very close. They fit inside the 18" BBS lightweight wheels ok but if you have a after market 18" wheel and the valve stem is behind the face of the wheel you may have a clearance issue.
Here are a few Photos of the install. When I get the car outside I'll get some better photos. Driving and braking feel evaluation to come in the following days / weeks depending on the weather. It's to hot for any track days in south Florida so I am not sure when I can you a true track day evaluation.
