As it turns out, TCE sells Wilwood performance brakes parts but NOT the rotors. After multiple pairs of warped rotors, I failed to get a product from TCE that would stand up to street driving.
In frustration, I called Wilwood and learned Wilwood does not make a standard part for 2003-2004 Mercury Marauder - the rotors used by TCE are not Wilwood!
If TCE was unable to recommend a rotor that would not warp every few months (3-4). As such, I do not recommend TCE brake kits.
