Thread: 1997 GTP Crosslace Wheels HELP

Question:

I have a 1997 GTP with Crosslace wheels. Everywhere I look, everyone is saying that the 98-02 f body brakes or '04 and up GXP brake upgrades will NOT work with cross lace wheels (caliper interference?).

Those of us who were unfortunate to inherit but love our Crosslace wheels might like a solution for their sub par brake systems that include their wheel package.

Any thoughts?

I heard the samething. I was told the wheel has a different shape on the inside than the other GP wheels. I dont think anyone ever showed pictures of the differents. It would be nice info to have

I was really hoping someone already had previous experience with this issue. I haven't a non crosslace wheel to compare my crosslace to. I suppose I could look into the 12" replacements as I do not want to exchange my wheels for different ones. Apparently the crosslace was a bit costly as an option and not many cars had them.

Has anyone had a chance to compare a replacement 12" rotor and caliper upgrade to the original?

Here's the wheel I have. Meant for 97 GP. Any thoughts on whether this will fit the 12" gm upgrade for brakes? I'm getting close to needing to purchase new rotors so any accurate info (not guesses) anyone had would be greatly appreciated. Thanks!

Okay, after a bit more looking I've discovered the reality of my situation and that is you can NOT upgrade your calipers if you have stock cross lace wheels. Suck. ClubGP: Grand Prix 12" Brake Upgrade (1997-2000)

I'm not sure if it's a heretical action to list a non-gpforumns site but here's my source. - Thanks for everyones help thus far

I thought impala brakes were the gm 12" upgrade.

Doesn't matter.

Asnwered by post above yours.

They are.

That's great to know! Thank you. Of course that's also a super tight tolerance. I decided to simply upgrade the rotors for now (stock size just better quality). I got them from rotorpros. Nice guys, parts from centric (I specified they give me an American shipment and not a Chinese). Whether they do is the honor system but all the same it's nice they cared enough to say I could. Without getting into the argument of whether after market drilled/slotted rotors hold up my car's the occasional drive fast and drive myself to work rig so seeing as I'm not pouring around the PIR repeatedly, I think I'll be okay. Part's, machine work (cnc), and shipping for both $100 flat.

Someday, I plan on upgrading the brakes entirely but until then I'll just focus on suspension because that doesn't work while my brakes do.

Again, thanks for everyone's help and I'll be checking up on the crosslace vs 12" upgrade for more info.
