bluegp Posted July 22, 2003 Report Share Posted July 22, 2003 When the current Alero/Grand Am GT came out, I remember reading about how they had really good 4 wheel disk brakes. Ever since then, I've wondered if those brakes could be swapped into something older (like a 1st gen W-Body). One plus is that the rotor's bolt circle would not need to be modified (I'm not sure about the center register however). I could not find the thickness and diameter of the rotors. Does anybody know? Has anybody heard of a swap? Quote Link to comment Share on other sites More sharing options...
Heza Posted July 22, 2003 Report Share Posted July 22, 2003 i think if i had a pre-94 w-body, i'd stick with a '94-'96 rear conversion and '95-96 conversion since i'm pretty sure the '96s got larger front rotors...atleast GPs did. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted July 22, 2003 Report Share Posted July 22, 2003 The current Alero/GA has good brakes for a car its size, but its brakes aren't that much better than a first gen W-body. The last gen 1 W-body front rotors were 11.2" diameter, 1" thick, rear rotors were 10.9" diameter, .433" thick. Alero/GA front rotors are 10.9" diameter, 1" thick, rear rotors .433" thick (don't know the diameter). Our rotor specs are actually better. Gen 2 W-body brakes, however, kills ours. They can have 12" front rotors that are 1.27" thick. Quote Link to comment Share on other sites More sharing options...
bluegp Posted July 22, 2003 Author Report Share Posted July 22, 2003 Thanks -- I was wondering if they (Alero brakes) were any better than the later 1st gen W-body ones. As for the 2nd gen W-Body brakes, has anyone heard of those being swapped into a 1st gen? I'm assuming none of the factory parts will work and that it would have to be a custom fabrication. Is that true? I guess if fabrication was involved, you'd just go with something better yet like Corvette brakes. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted July 22, 2003 Report Share Posted July 22, 2003 Yes, lots of fabrication would be involved to go to gen 2 W-body brakes, which is why I'm skipping those and going right to the Corvette brakes. Quote Link to comment Share on other sites More sharing options...
