H&R 28664-1 Sport Springs for BMW Z4 G29 and Toyota GR Supra A90 J29

Give your G29 Z4 or A90 J29 GR Supra the stance and handling it deserves with this H&R front and rear coil spring set. Expect an approximate 30 to 35 mm ride height reduction that tidies wheel gap, boosts cornering confidence and enhances steering feel while keeping day-to-day comfort intact. This is the proven chassis upgrade for drivers who want sharper response and a purposeful look.

We have installed this kit for customers and run it ourselves. Feedback has been excellent, with owners noting crisper turn-in, flatter body control and a far cleaner silhouette without ruining the ride. Ideal for spirited road use and weekend blasts.

Highlights

• Approx 30 to 35 mm drop at both ends for a balanced, level stance
• Variable-rate springing that stays compliant over rough surfaces yet firms up when you press on
• Direct-fit coils that work with your factory shock absorbers
