Autocross Alignment Specs by Car
The alignment specs below are community-derived starting points for autocross use — not gospel. Your ideal spec depends on your spring rates, tire, ride height, and driving style. Use these as targets to get on the alignment rack, then refine based on tire wear and lap time feedback.
Aggressive negative camber (−2° to −3°) accelerates inside tire wear on the street and may affect brake performance. If the car is also a daily driver, consider running a milder spec (−1° to −1.5°) or accept faster tire wear on the inner edges.
Mazda MX-5 Miata (ND 2016+)
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Camber | −2.0° to −2.5° | −1.8° to −2.2° | Camber plates required to reach this |
| Toe | 0° to slight toe-out (−0.05°) | Slight toe-in (+0.1°) | Toe-out front improves turn-in |
| Caster | Max available | N/A | More caster = more camber gain in corners |
The ND Miata is camber-limited with stock components — most STR competitors run camber plates (Flyin' Miata, MeisterR) to reach useful negative camber. Without plates, you'll be stuck around −1° to −1.2° front.
Toyota GR86 / Subaru BRZ (2022+)
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Camber | −2.0° to −2.8° | −2.0° to −2.5° | Rear adjustable via OEM eccentric bolt |
| Toe | 0° to −0.05° | +0.05° to +0.1° | Keep rear toe-in for stability |
| Caster | Max available (~5.5°) | N/A |
The GR86 has rear camber adjustment via OEM eccentric bolts — one of the better stock platforms for dialing in alignment. Front camber plates needed for more than −1.5°.
Subaru WRX (VA 2015–2021, VB 2022+)
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Camber | −2.0° to −2.5° | −2.0° to −2.5° | Aftermarket camber bolts help front |
| Toe | 0° | 0° to +0.1° | |
| Caster | As much as available | N/A | Limited on stock geometry |
AWD WRX alignment is more constrained by class rules — verify that camber adjustment hardware is legal for your class before purchasing. Whiteline eccentric camber bolts are a common Street Touring solution.
Honda Civic Type R (FK8/FL5)
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Camber | −2.5° to −3.0° | −2.5° to −3.0° | Wide tires benefit from more camber |
| Toe | 0° to −0.05° | 0° to +0.1° | |
| Caster | Max available | N/A | Stock caster is decent on FK8 |
The Type R's wide 245/30R20 tire footprint (FK8) responds well to aggressive camber. Many GS-class CTR drivers run close to −3° front to get the tire working properly on the wide rubber.
Ford Mustang GT (S550 2015–2023)
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Camber | −2.0° to −2.5° | −1.5° to −2.0° | Rear camber bolts recommended |
| Toe | 0° | +0.05° to +0.15° | Keep rear stable — it's a heavy car |
| Caster | Max available | N/A |
General Guidance
- Always get a full 4-wheel alignment after any suspension change, including ride height adjustment
- Record your alignment sheet — bring it to future events so you know your baseline
- Tire pyrometer readings are the best feedback for camber optimization — inside edge should run slightly hotter than middle and outside
- More camber is not always better — too much causes the tire to run on its edge, reducing contact patch
- Find an alignment shop that understands motorsport — not a quick-lube chain
