T fitting instead of prop. valve, what is the rational? Options

[DanT]

Ok, I know this has probably been discussed in many threads before. But, what is the reasoning for replacement of the Prop. valve with the "T" fitting for the rear brakes. Does the prop. valve cause more line pressure to the fronts or the rears when it is operating properly? I want to understand the engineering aspects of this modification.
I will be running "M" calipers with mythical billet hubs in the front and stock 914-4s in the rear.

Does locking the rears mean you ARE going to spin....NO, just release the pedal a bit and they start rolling again. You can also use this to rotate the car, as in Karting, which has only rear brakes. Finesse is the key. The T allows the rears to actually work, which they really don't unless you really get on them with the P valve. Spinning is not inevitable. Just my 2 cents.

Some like to free the car up upon entry into a corner with some rear brake bias. It's all in how you like the car setup.

Karts with rear brakes only require some degree of forced technique, since rear brakes is all you have to work with. Ever try a direct-drive kart? Here again, it forces a technique change or adjustment. You are correct, that many often forget to modulate the brake pedal to get the desired result.

A street car needs to be capable of dealing with a very broad range of conditions. I inagine everything is designed to err on the side of safety.
