The 2011 Chevrolet Camaro base and LT trims carry over the Zeta platform's core fitment geometry from the launch year with one meaningful update: GM added the optional Performance Package to 2LT, which includes the Brembo four-piston front setup previously reserved for 2SS. Any 2011 LT with RPO J55 or the 2SS brake upgrade needs 18-inch minimum wheel diameter to clear the 348mm caliper — 17-inch fitments from older vehicles will not work. Stock V6 wheel: 18x7.5-inch at ET+52, 225/55R18. Stock 2SS: 20x8.5 front and 20x9.5 rear at ET+49/ET+55, 245/45R20 and 275/40R20. Owners on 6-piston Wilwood or Baer front setups run 20-inch minimum diameter with ET+30 to +35 to clear the larger caliper body. Rear fitment window: ET+32 to +40 on 20-inch is the safe zone before the subframe bracket clips wide lips at full bump. The 2011 Camaro shares the same 5x120mm and 66.9mm hub spec as all 5th-gen builds, so wheels are interchangeable across 2010-2015 without bore adapters. Staggered setups must use a non-staggered tire rotation plan or two full sets — rear 275s cannot swap to the front 245 position. Maximum confirmed rear tire without fender modification: 275/40R20 on stock suspension. V6 base with 18-inch aftermarket: ET+35 to +50 is the safe offset window before strut interference at full lock.
