Thats right the shims are sliding off with less than 1 k miles !!
Hawk has sent me a new set, however under close inspection the adhesive they use looks only to be a double sided tape (the new set is done the same way). They claim they are epoxied and I can tell you this is not epoxy and can be dangerous.

Basically, the shim is a sham.

That's disturbing. I've gone thru 100s of sets of Hawk, mostly on the track. And have 15k on a set on the C4 but they're not the type with shim.
I'm not defending Hawk in the least though for this.

Mick, do you have them off the car yet and can you post a pic with them out of the caliper?

Kudos to Hawk for sending you new ones and it's not supprising that they're exactly like the others (they just pulled another set off the shelf).

Did they ask for pics or the old ones back? If not, they're not really looking to fix a problem.

Does that shim have the lining wear indicator on it?

Bill, basically the pic I posted is what I sent them per their request.

Yea, I don't understand the "why" of it all aside from the fact of what the adhesive looks like. After I found the issue a google search provided many on other boards (miata, beemers and the like) have experienced the same issue. Many just removed the shim, and all was well, although several posts talked about their rotors getting sawed deeply from the shim before discovering the problem.
However, the rep. at hawk stated that I can just go ahead and remove the shim, but he said I paid for them to have shims, so there was no problem. They didn't once hem and haw about replacing them and he told I could do whatever I wanted with the old ones....of course I kept them. I can take a pic later of them (off the car, and the backs were the same way)..I haven't tried the new ones yet, maybe today or tommorrow...and am also getting ready to test the hose so I need to feel confident of the brakes.

Good luck.
I've never heard a complaint on Hawk pads but, my experience is limited to newer C4s, C5s and quite a few different racecars, none of which had shims though.

At least they were upfront with ya. I hope their engineers address the problem.
Better than many vendors out there.
