7.25 rear from 5x4” to 5x4.5” bolt pattern
What backspacing did you specify for those 17x7 Torque Thurst ii wheels?
Thank you for all the detailed information and photos that you posted!
Following up on my own question (and thanks to all who posted on here on
@Ruinnations ' thread!)
For our 1967 Barracuda:
I went with 16 inch rims and 225/50r16 tires.
5 x 4.50 in. Bolt Circle, 4 in. Backspace
American Racing VN215 Gray Classic Torq-Thrust II One-Piece Wheels VN2156765US
Wheel, VN215 Classic Torq-Thrust II, Aluminum, Matte Gray, 16 in. x 7 in., 5 x 4.50 in. Bolt Circle, 4 in. Backspace
Wilwood front discs. Stock A-body drum spindles.
I will post all this elsewhere in a new thread along with photos.
Tire sizing:
| c | 225/50r16 | | 24.9 in outer dia | same dia as stock | - |
| YES, this is it! | | Section width | | 8.9 in width | stock: 7.3 | |
| Notes July 2024 | | Rim width | | 6.0 - 8.5 in | | |
| | Sidewall height | | 4.4 in | may be ok - YES was OK! | |
| | revs per mile: | | 836.74 | +0.27% compared to stock | |
I originally purchased 15 inch Rallye wheels with the big bolt pattern 5 x 4.5, but the center hole was too small for Wilwood front disc spindles. So I went with American Racing wheels above and increased to 16 inch diameter.
I purchased 225/60r16 tires - but they did not fit. They severely clipped the lower edge of the front fenders. Rather than trim-back the fender by 1/2 inch (1 cm), I switched to 225/50r16 which are fine.
