As with all modifications, it depends what you are looking to do with your car. I am running the Baer GT front brake kit. I chose this kit because I wanted to have enough brakes to road race my car at an affordable price. The Baer kit uses a bigger rotor, which is the major thing you want to improve brake performance.
The standard kit cost is about $1,000 (at least it was when I bought it) and they work great! I also like that it uses C5 Corvette pads. These are available everywhere. Twice I have waited until the day before a road race to replace my pads. All of my local auto parts stores have them in stock.
The TCE kit is also a great kit and is reasonably priced. I would not hesitate to run a TCE kit. Plus TCE has a rear kit which would be nice. The Mov-it’s are great too, but a bit pricey.
