$200 difference? Try more than that.
If you get the equivalent size kit for Rotora, that will be over $1500 and the Wilwood is only $900. Both 13" rotors.
I will most likely be going with the Wilwoods.

I have not decided on which BBK for my Time Attack tC but I am running 18x9.5 wheels and 265mm R888 tires under rolled fenders.
If a project works out I will be moving up to 18x10.5 wheels and 285 tires, or even wider yet, considering a body kit and 305 tires next
The 285 will fit with massage stock front fenders, Ptuning already runs that setup
--------
I have 6 and 4 piston Stoptechs for my race Vette, over $6k with pads, ouch. They have only been used for about 2 blocks, on and off the trailer, etc, so they are up for sale since the Vette will be down for at least another year. Perhaps I can find hats and brakets, or make brackets, and run them on the tC

Yeah, contact stoptech. The brackets are the main difference, the whole caliper setup is pretty generic. I run the stoptech 4 piston kit. Did you get to heat cycle them if youve only ran 2 blocks with the brakes? Your really missing out if you havent had a chance to play with those stoptechs. The car stops so hard, I am afraid of ruining tires by putting flat spots on them.

I know how good Stoptechs are, I have used them before and two racers I know are getting incredible pad and rotor life out of them. For real racing that is a huge cost savings benifit as I know othes that spend thousands a year on rotors and pads and rebuilding or sometimes replacing calipers.
Actually brackets and rotor hats have to match the application as well as piston size in the calipers and front to back of the car, the vette being RWD with closer to 50/50 balance than the FWD tC could mean they are not even close to the right size.
And the lines may not fit as well, that leaves just the rotors that are interchangeable without further investigation.
Caliper pistons have to be measured for diameter, one side only so 3 out of the six, 2 out of the 4 (rears) and then compared to the area of the stock calipers.
If the size is right as well as ratio front to rear(bigger in rear is not to hard to manage with a flow reduction device(often times called a bias adjuster which is is not;) then ok to use the stock master cylinder. If not close then you get the wrong pedal travel, to soon, to late pad contact, etc. So maybe have to change to a different unit, not to hard to math out either.
Unless exceptionally lucky the hats just will not work, if lucky they can be rebored to the correct bolt pattern.
Brackets, not cheap, if available as replacement parts, cool.
Bottom line, there is a great deal to figure out but it may be viable so I will look into it, I own brand new brakes, would love to be able to use them instead of losing money and buying new again (and you cannot just buy new stoptechs for the tC, not the ones I want especially)
