Mazda RX-7 SA22C – Full Setup Service in Adelaide
A Mazda RX-7 SA came into Autosport Tyre World for a complete setup.
The customer brought in their own wheels and wanted the car set up properly for real driving.
Step 1 – Wheel Installation
The vehicle came in with a set of Simmons wheels supplied by the customer.
Classic wheels like these are part of the car’s identity, so the goal was to:
- install correctly
- check clearances
- ensure proper fitment
Step 2 – Tyre Upgrade
We fitted:
Yokohama Advan AD09
Size: 205/45R17
Shop AD09:

Why This Tyre Was Chosen
For a lightweight RX-7, AD09 offers:
- modern grip levels
- responsive steering feel
- strong stability under braking
It transforms how the car feels compared to older tyre designs.
Step 3 – Wheel Alignment
After fitting wheels and tyres, the most important step is alignment.
We performed a full alignment check and adjustment.
What We Found
Initial readings showed:
- rear toe significantly out
- front toe uneven
- overall geometry not balanced
👉 This is common on classic cars
Step 4 – Adjustment and Setup
We adjusted:
- front toe for better straight-line tracking
- steering balance for improved control
Rear adjustment was limited by the vehicle’s original design, which is typical for older platforms.
Step 5 – Final Result
After completing the setup:
- the car drives straighter
- steering feels more predictable
- rear end is more stable
- tyre contact is more consistent
Why This Process Matters
Many people only focus on:
- wheels
- tyres
But without proper setup:
👉 the car will not drive correctly
The full process matters:
- install wheels
- fit tyres
- align the car
Classic Cars Need a Different Approach
Unlike modern cars:
- alignment range is limited
- components may have wear
- setup requires experience
The goal is not perfect numbers.
The goal is:
👉 making the car drive properly
