rx-7 questions

[HPKY59A@prodigy.com ( BENNY DEMENT)]

First does anyone on the list know if the 88-89 rx7 GXL has a torsen 
rear end?  second need some advice on some rear brake pads for my 85 
rx7 se. With the stock proportioning valve removed and an adjustable 
one in place.  I still lock up the front brakes.  I have adjusted it 
to allow full pressure to the rear but it is not enough.  So I'm 
thinking of useing more agressive pads on the rear.  Any suggestions?
