Just a post-upgrade follow up after almost a full season with this kit installed:
I really enjoy this TCE kit. There were no fitment issues with the stock wheels (it's a pretty tight fit). With the kit itself, TCE actually shipped the wrong front adapter brackets originally, but when I posted pics to Todd he recognized the error and shipped the correct brackets. I had to use every single shim washer in the kit (including the extra shims from the rear kits) to get enough clearance for the rotors -- I did wish for a few extra shims. Installation went pretty smoothly except that I needed a hub puller to remove the dust shield on the rears, so that introduced a delay while I hunted one down. The kit did not come with Sky/Solstice instructions, so a few things required some head-scratching.
Brake performance is fantastic. With the track pads installed, removal of loose fillings is as simple as a stomp of the stop pedal. At Todd's recommendation, I went with the BP10s for the street, and for the track I have PolyMatrix E on the front and BP20 on the rear. Balance is very good.
I'm getting pretty good at swapping the pads -- fronts are a breeze to change, the rears a little less so because a wind-back tool is required and the caliper design prevents the use of any through-style wind-back tools. I have been using a cube adapter on my socket wrench and a pry bar which works, but is a little awkward.
