there is a large range of brake parts available from wilwood. What i have found is that most kits (for any car)tend to use the lowest end parts possible(this does not meen they are not good, just the lower end of the performance parts). This goes for both rotors and calipers. You don't need overkill, but you want consistent, worry free, fade free brakes for your car and usage. Different brakes may also give the possibility to save some weight also since aluminum 4-pot calipers weigh less than triumph calipers, but you will probably put that weight back in by putting in the largest vented rotors practical. When you look at vented rotors, there are different details to consider:
straight vane, curved directional vane, drilled, slotted, weight, diameter, and width.
holes and slots reduce the contact surface area but have some benefits when pushing the limits of your brakes. Many race cars have carbon brakes-no holes or slots.
new compound pads don't gas off like the old ones. I like the wilwood GT rotors, some slots, curved directional vanes.
