I have them available for the forenza/reno and can get them made for the aveo if there is intrest. If there is a kit already out there by wilwood that'll fit up with an extra washer here, or a little grind there then if there is only one person intrested I could probably get you a kit.
For the forenza we have front brakes available in 11", 11.75", 11.9"x1.25" (track setup), and 12.2" kit. All with two peice disc both drilled and/or slotted (plain if you'd like) with 4 piston calipers.
Prices for the forenza/reno are from $650-$2000 depending on the setup. The best bang for the buck kit is about $800 shipped, and with that kit I managed to lock up the wheels at 110mph after 17mins on the road course and with 215mm azenis tires.
