i think it is precisely because others find that you are ill informed and so they are trying to explain to you the futility of your plan. So instead of saying you would not discuss the issue, use that as a learning opportunity.

The whole discussion of weight transfer resulting in less traction at the rear is reason enough not to mess with the brakes.

anyways, a few additional thing to note. if you are cooking your brakes coming down Genting then perhaps it is better to reexamine how you are actually driving.

Also understand the physics behind friction braking: your wheel must rotate for it to work. With the load off your rear you likely end up locking your wheel too easily (which causes ABS to kick in) so your wheels are not rotating as much as they should be which can actually decrease braking performance. on the subject of cooling, since most of the braking is done by the front brakes, they naturally heat up more than the rear and have you considered that perhaps the cooler rear might actually lose heat at rate comparable to the front therefore making rear disc pointless?

make no mistake, i love all around disc brakes but you should really consider your actual application before diving in
