Choose Your Setup: HIPERMAX S (Street Performance) or HIPERMAX R (Track-Focused Control)

If you’re upgrading suspension on your GR Corolla, HKS offers two standout coilover options — each engineered specifically for the GZEA14H chassis but tuned for different priorities. Whether you want a refined daily-driver setup that still improves handling, or a more aggressive configuration built for higher grip and track pace, this page makes it easy to pick the right kit.

Quick Comparison (Which One Should You Buy?)

Choose HIPERMAX S if you want:

• A daily-friendly ride with a major step up in body control

• Better stance and adjustability without “racecar harsh”

• A well-rounded setup for street driving, canyon runs, and occasional events

Choose HIPERMAX R if you want:

• Maximum chassis control for track days, autocross, and aggressive tire setups

• Higher spring rates and sharper response

• More capability when pushing hard (especially with high-grip tires and alignment)

Product Overview

The HKS HIPERMAX S is the ideal coilover choice for GR Corolla owners who want a noticeable improvement in handling and stance while keeping the car comfortable and composed for real-world driving. It’s engineered to reduce body roll, improve turn-in response, and give you control over ride height and damping — without beating you up on daily commutes.

This kit is the “do-it-all” suspension upgrade: capable and responsive when you drive hard, but still refined enough for everyday use.

Option 2: HKS HIPERMAX R Coilover Kit

Part #80310-AT007 – GR Corolla (GZEA14H)

Product Overview

The HKS HIPERMAX R is the more aggressive, track-capable coilover system for the GR Corolla. It’s built for drivers who prioritize precision, reduced chassis movement, and consistency at the limit — especially when paired with sticky tires and a performance alignment.

Compared to the S, the R is tuned with a more performance-forward approach to maximize feedback, stability, and cornering control. If your GR Corolla sees track days, autocross, or you simply want the most serious suspension option HKS offers for this chassis, this is the kit.

Key Features

• Direct-fit full coilover kit for 2023+ GR Corolla (GZEA14H)

• 30-level damping adjustment (front and rear)

• Adjustable ride height (front and rear)

• Higher spring rates for increased chassis control

• Built for high-grip performance driving and more aggressive setups

Best For

Track days, autocross, aggressive canyon driving, high-grip tire setups, drivers who want maximum control and response.

What’s Similar Between S and R

Both kits deliver the core benefits GR Corolla owners want:

• Ride height adjustability for stance + center of gravity improvements

• Damping adjustability so you can tune comfort vs response

• Vehicle-specific fitment for proper geometry and clean installation

• Premium HKS engineering aimed at real performance, not just looks

Frequently Asked Questions (FAQ)

Will these fit all 2023+ GR Corolla trims?

Both kits are designed for the GR Corolla chassis (GZEA14H). Always confirm fitment if you have a special edition or unique configuration.

Do I need an alignment after installation?

Yes. A full alignment is strongly recommended after installing either kit to ensure proper handling and tire wear.

Are these “too stiff” for daily driving?

• HIPERMAX S: Generally the better daily option if comfort matters.

• HIPERMAX R: Still street-drivable, but tuned more aggressively and will feel firmer.

Can I adjust ride height without changing damping?

Yes. Ride height and damping adjustments are independent, so you can set stance first, then dial in ride quality.

Which one should I choose if I’m on 18x9.5 wheels and sticky tires?

If you’re running a more aggressive wheel/tire setup and plan to push the car, HIPERMAX R typically makes more sense due to its higher control and performance tuning.
