Ok, I bought my car a while ago and it came with a box of parts another guy took of of his car. In the box were single piston calipers and drilled rotors. The bolt pattern is apparently the 4x114.5. I've read every where that you should be able to directly bolt on the brakes from an se to a gsl. I have an 85. My problem comes in at the backplate. The caliper bracket didn't fit so I drilled new holes and made a spacer so that the caliper bracket would bolt to the backplate and go around the rotor. So, test fit time... I tried to put the caliper on and it extended to far down and back so that the idler arm (i think) is is the way and it won't fit. Now I'm thinkin I have to rotate the backplate about 10 degrees counter clockwise for everything to work. NOW THE REAL QUESTION... Is there a different backplate between se and gsl? or am I just fubar? I really need this all done by thursday night or friday morning cuz as we all know SS is on saturday and I'm volunteering. Any and all help is appreciated!

 

I believe you need the front struts from an SE to use the SE brakes. Both the strut and backplate are different.

Either an GSL-SE or GSL strut assembly will do.

 

um, k, so I'm going to jb weld the hols that bolt the back plate on, rotate it counter clockwise just a bit and press new holes. Will the jbweld hold? Wow, this has got the be the ultimate in cheap *** brake upgrades.

 

I don't think I'd trust JB Weld ANYWHERE on my brakes...

 

I agree with that. On that strut issue. So what do you need from the SE to use the SE brakes on the GSL struts, just the backing plate?

Thanks.

 

I've never done it, but the strut and spindle are supposedly the same, but from what I understand everything else is different...

 

I believe that's correct for 84-85 models, but not before that.

 

Well, there were no GSL-SE's before '84, so yeah... You're probably right...

 

No, definately decided against the jb weld. I'm just going to stick with the stock rotors until I get the whole se set up. On another note, driving back from seven stock tonight, after a little bit of driving if I touched the brakes at all over say 20 mph there was massive vibration. Haven't gotten the car up and wheels off yet but that was definately scary.

 

Sounds good
