Solly,
Wish you luck with your project.I have tracked my SPF Coupe #19 at 5 different track weekends-Summit Point,VIR,Carolina Motorsports Park.While getting the car ready for this year's One Lap of America at VIR,I blew a rod through the
oil pan.The engine is being rebuilt by Roush now,including an Accusump.Better late than never.If you are interested,I'll send along the new engine specs when I receive them.The original motor was a 401 Windsor with a Dart block.
A couple of thoughts.I would try the "stock" rotors and see what you think.The braking with these is excellent.
The biggest problems with the Coupe are a real loose rear end and power application coming out of turns. The car does NOT trail brake,and it has taken some time for me to learn what the car is telling me through my butt!It is a real handful on a track,but loads of fun.
Best of luck,and maybe we'll see you at Summit or VIR.
