LOL Yes they are total overkill....
but this is how I justified it....
$550 for the willwood setup (pads, discs, calipers AND braided lines) delivered
vs
new discs (RDA ebay stuff) - $200 delivered (I'd personally go DBA but whatever)
so roughly $350 more But that also gets me bradided lines, and much better brakes. Braided lines for the front would also cost around $100.
So we're looking at $250 difference to get massive brakes! Not to mention I'm fairly sure the rotors are the premium ones with hats. Plus more surface area, means longer lasting braking (assuming the same rate) and supra TT brake rotors are not much more than MR2 ones :)
Very happy. Will see what the rear brakes condition is.
edit: sorry to hear that the starcorps didn't clear the brakes. :( the enkeis were one of the rare 17" rims to clear the supra TT front calipers, but there was VERY little room. I would recommend these as a fantastic wheel for track use on a supra :)
