Questionable Fix No More Department: GM appears to have upgraded the Camaro's noise-abating caliper weights to something a bit more substantial and permanent. The stick-on lead wheel weights are gone!
The quick recap: Increased caliper mass is often used as a solution to brake noise. The Brembo units on early 2010 Camaros were fitted with a last-minute band-aid in the form of stick-on lead weights. Those weights resembled — and most likely were identical to — the weights mechanics use to balance wheels. It appears to be a clever stop-gap fix until you consider that A) it looks like garbage, and B) the lead could melt and/or adhesive separate if brake temperature exceeds a certain point. (Lead melts at 627 degrees Farhenheit, so the latter is probably a bit more likely.)
The permanent fix, as reported by Camaro5, appears to involve a set of circular weights hung off the back of the caliper. The new arrangement can be seen below. Begone, hooptyism! Back from whence you came!
