As for Stoptech the 355mm is the biggest you can get in rear the last time I checked. I bet if they did have a 380mm rear they would be on your car . Just having fun with you.

My opinion is to do what you like as you have to live with it.

Still wouldn't get 380 rear Stoptech. I think the bias is more like 90/10, but it is extra cost and weight for no appreciable gain in the rear. Unless you move to a manual brake bias adjustment to be able to set the rears to lock just after the front, simply not worth it. Then you are into a race car setup.
