He's got a 250S and he wants to upgrade to V8 brakes, as stated in the first line of his first post.
I've been looking into various combinations and the best option is indeed the 3.5/4.5/6.3 brakes with carbon kevlar pads. Straight fit and more than enough braking power. The upgrade won't give you more braking power (apart from the added one from the carbon kevlar pads) but the vented disks will give you better resistence to fading.
Other options are possible like fitting Gen2 126 rotors and callipers but the work and expense involved is not worth the gain in my view.
