Wilwood Superlite & Superlite 2 calipers can be mounted in front with no adapter, only a 1/8" thick centering spacer, on 0.81" thick rotors (stock thickness & dia). But you must carefully mark, then drill & tap a third metric mounting hole identical to the 2 OEM holes, in the extreme bottom of each steel steering arm. Some arms will need to be built up with a small weld boss to prevent cracking of the new hole. The weld will be in a non-stressed area as far as steering is concerned, but try to minimize the heat input by TIG-welding if possible. The two mount holes in the Wilwood calipers must be slightly enlarged to the stock caliper bolt diameters. Note that the caliper will use the stock top bolt hole in the steering arm, and will depend on your precision to locate the new bottom hole. Get it off a little and the caliper could rub the front wheel. Adapting vented 0.81- thick rotors in front is easy (early Porsche 911 rotors with your own home-made 1.0" thick 'hats' fit well). In the rear, the adaption is complicated by the need to clear the protruding part of the cast iron wheel bearing carrier, so lots of lathe work is necessary. If you aren't pretty well equipped as a do-it-yourself-er, I suggest you have this done by a competent pro (P.I. Motorsports?) or use the available caliper adapters and/or rotors for sale by most Pantera parts vendors. A loose caliper or malfunctioning brakes could put your car in the major-repair shop and you in the Hospital! Also note that 0.81"-thick rotors, vented or not, will not stand up to heavy track use as the thermal mass of such rotors is too small for a 3200-lb Pantera. They will be just fine for street and limited open-track events, though.
