So it won't lock up the rears first with a T instead of a proportioning valve?
the important info here was "if you upgrade your front brakes" ...
if you do so and keep the rear brakes stock and you keep the stock valve, your rear brakes don't get any pressure anymore.
you effectively only brake with the front.
putting in a "tee" gives you more pressure in the rear, so now both, front and rears, do some braking again.
if you also upgrade the rear brakes, you should either use the stock valve or switch to a adjusteable aftermarket valve.
here is how it feels driving:
1) stock valve
upgraded front to 86' carrera suspension, including brakes etc.
rear was still stock. when braking hard, the nose would dive down dramatically, breaking was much better, but the front was doing all the work.
2) with the TEE
removed the stock valve with a T and now under hard braking, the whole car goes down evenly and just before locking up the front goes down a bit more. the rears now do something again, and the balance seems perfect.
