Wells information

Wheel Information:

All 15" Wheels : Will not fit on 89 and newer rears with aluminum calipers, as the rear caliper interferes with the inside of the wheel

GTA Wheels & All other 16" Wheels : All 85-92 16" wheels are paired as Front wheels (4.75" backspacing) and Rear wheels (5.25" backspacing). These wheels will replace all factory 15" wheels. All 16" Trans Am & Formula wheels are labeled "Front" & "Rear" on the backside. They can be identified without removal by noticing a deeper dish on the "Front" wheel as pictured. 86-87 GTA wheels have no dimples on the spokes, while 88-92 GTA wheels have dimples as pictured below.

Front GTA wheel has a larger depth than the rear wheel Rear GTA wheel has a more shallow dish than the front wheel 86-87 GTA wheels have no dimples 88-92 GTA wheels have dimples

82 - 92 Wheels : Will not fit on 93 and newer vehicles properly. Wheels will stick out approximately 2" past wheel well when installed on a 4th gen. This is due to the difference in backspace. There is no way to correctly install these wheels on a 4th gen.
93 - 02 Wheels : Will not fit 82-92 Firebirds without adapters. The wheels are interchangeable between front and rear axles. The spacers/adapters required for this conversion are approximately 2.125" thick. This is due to the difference in backspace. These wheel adapters are available through www.vettebrakes.com under PN 13770 (standard lugs) & PN 13770M (metric studs), priced at $179.95 pair as of 11/03/03. The adapters will also work on 1st and 2nd gen F-bodies as well.
Chrome wheel interference problems on 93-96 F-bodies : Chrome wheels will not fit on rear of 93-95 Firebirds due to a lack of clearance between the wheel hub and the rear axle shaft. Factory 93-96 axle shafts have a 70.75 mm diameter hub face, while the 97-02 Chrome wheels have a 70.5 mm diameter hub opening. Minor grinding/machining is mandatory for installing those wheels on 93-96 models.
