I got a set of Corbeau Sport seats from Calmini for my Trackick, with the brackets that are a direct bolt in. They are very well made but a bit pricey, about $700. a set. I'm probably going to have to sell them though as they are a bit too narrow for my wide ass. Corbeau makes a bunch of seats but only a very few will fit in the narrow space of a Trackick. I also tried some of those so called "racing seats" from a local auto parts warehouse, and they are too wide at the shoulders to fit in a Trackick, unless you leave athe doors open! And making the brackets is a PITA unless your a really good fabricator.
