12" Brake Rotor Upgrade Questions

[Shutterbug5k]

Ever since I’ve owned my ’99 GP GT I’ve felt the brakes were a real weakness when it came to stopping power and safety. I’ve been reading the following articles about upgrading the front brakes to 12” rotors with great interest and I’m about ready to give it a try.

I do have a couple of questions before I get into this project though.

1. Has anyone done this successfully on a stock ’99 GP GT with the stock 16” 5-spoke wheels? In other words – will everything fit under the wheel?

2. Would an OEM 12” rotor or an aftermarket drilled & slotted 12” rotor be a better choice?

This forum has been the source of a lot of great information and I look forward to your comments on this project.
