I bought my 04 termi with the Brembo Cobra R Brakes on the front..well i am looking at going to a drag setup for the front using aerospace or wilwood brakes for the front so i can run 15" wheels. Currently the 17" alumistars won't even clear that brake kit. Do I have to change out the complete spindal and brake setup or are the spindals the same for GT's and Cobra's just different caliper mounts etc?
