nah, super slut gives you what 4 mm extra diameter, a bit of hassle and still only twin piston sliding caliper. Smaller brakes (width, diameter, and pad size)on the gemini dealt with more weight, more applications /km and longer sessions than this will ever see.
with a set of proper pads and some ducts these will be more than fine. If can be bothered when I get the rear suspension apart for rebushing I might fit some AE101 (266 m non vented rears + hub, and caliper etc), if i can get them for almost nothing.
if i want to get stupid with front brakes I'll just drop 1000 bucks on a set of wilwoods, adapter and discs from MRP.
