Wheel backspacing
 

Hey as some of you know i put a fourth gen rear in my 86 and the brakes have been nothing but trouble lol, besides that what backspacing would set the wheels back in a little bit more and i can still fit a nice wide tire back there. thanks in advance.

Stock 4th Gen wheels are 16x8" with a 6-5/8" backspace. They also used 17x9" wheels on the SS/WS6 cars, with a shade less than 7.00" backspace. Then there's the 17x11 ZR1/Grand Sport wheels than many of us use with a 7.93" backspace.

what brake issues? and did you already have the PBR aluminum rear brakes?

my rear brakes refuse to blead, i can put my pressure bleader on and it will shoot fluid out like a mofo but once i take that off it doesnt work this was with the ls1 master on there i took that off and put a new thirdgen style on but my bleader doesnt like to work well with the old style master's and i am on my second prop vavle so im sure that isnt it. im clueless and the car is going off for paint in less then a month now and i need to get this stuff figured out, put on top of that now im having ignition probs when i turn the car to acc it starts cranking, i ripped out the ignition switch tonight and im gonna grab a new one tomorrow.
