The problem with the development of a rear brake system is the E-Brake crap that needs to be taken into account. And for a platform that has very little support, comparatively, we're lucky they make a front kit.
The product is priced very well, even at full retail. Brembo 4-Piston Front Brake kits range from $2k-$3k for just the front kit. But those kits also have 4-piston calipers and 2-piece rotors.
So what you get from Baer is worth every penny. If you want to find out more about Baer Brakes you can go to their website:
