I've been using Alcon big brake kit 343 mm rotors http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-front-6-pot-o343x32-nissan-skyline-r32-r33-r34-gtr.html with low offset 17" Enkei wheels, for two years. They perform very well on track, with yellow Pagid pads, much better than AP kit that I had on R32. No BIAS issue with stock rear calipers and DBA rotors. I'm going to sell my front kit very soon, and change for Alcon 365 mm kit with 350 mm rears http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html but need to find correct wheels first.
