Subaru WRX STI Fitted with WedsSport SA-72R + Michelin PS5 at Autosport Tyreworld

At Autosport Tyreworld, performance cars demand performance upgrades — and this iconic Subaru WRX STI is no exception.
This stunning blue STI visited our workshop for a complete wheel and tyre upgrade, combining Japanese racing engineering with premium Michelin performance rubber.

The result is a sharper stance, enhanced handling, and a cleaner, motorsport-inspired look that perfectly suits the STI’s rally-bred DNA.

🔥 Wheel Upgrade: WedsSport SA-72R – 18x9.5 +38 (5x114.3)

The customer selected the WedsSport SA-72R, a lightweight, flow-formed wheel engineered for spirited street driving and occasional track use.

Key Benefits of the SA-72R:

• Flow-form manufacturing = lighter & stronger

• 9.5-inch width increases tyre contact patch for better traction

• +38 offset gives a functional, aggressive fitment

• 72-spoke split design maximizes brake clearance

• Perfect fit for Subaru WRX STI (5x114.3)

This setup gives the STI a muscular, track-inspired appearance while reducing unsprung weight.

🛞 Tyre Upgrade: Michelin Pilot Sport 5 – 245/40R18
