Rear brakes for track/street car?
 

I am currently lining up more parts for my 69 Firebird track/road car. I have Wilwood FNSL 6-pistons with 1 piece slotted rotors for the front and am looking at options for the rear. I will be running a Tru Trac in either a 9" or S60 rear. Since I will be tracking the car, should I go with a floating caliper set up for the rear? I would like something that will visually compliment the front brakes, but performance comes first!. I don't think I want to go the floating axle route.
