1985–1992 production; body-dependent · FC
Mazda RX-7FC
The FC RX-7 includes turbo, naturally aspirated and convertible variants plus many converted cars.
Before you choose wheels.
A good-looking setup is only useful if the details match your car. Start with these generation-specific checks.
- Confirm the fitted hubs and brake package before comparing a Turbo II setup with another FC.
- Identify original hub and brake hardware versus common swaps before using another car’s wheel specifications.
- Record body alterations, tire model and ride height because a rotary build photo alone does not establish clearance.
Record the complete setup.
Track front and rear separately, even on a square setup. Wheel diameter and width alone cannot establish clearance.
- Wheels
- Exact brand and model, diameter × width, nominal offset, bolt pattern and hub bore.
- Spacers
- Explicit front and rear thickness in millimeters. Enter zero only after confirming there are no spacers.
- Tires
- Brand, model and full size on each axle. Nominal sizes do not guarantee the same measured section width.
- The car
- Market, model year, trim, body style, brake package, suspension, alignment and any fender modifications.
- Real-world result
- Rubbing at steering lock, under compression and with passengers or cargo. Include conditions, not just “fits.”
Effective offset = wheel offset − spacer thickness
A spacer moves the wheel outward, but an offset calculation does not prove brake, tire, suspension or body clearance.
Year ranges are generation guides, not VIN decoders. Market introductions and model years can differ.
