Technical & Fitment Notes
- Confirm the exact Hipermax series/configuration, included upper mounts, adjustment features, and application-specific spring/damper specification before installation.
- A performance alignment is recommended after installation; final ride height and alignment should be set around tire clearance and intended use.
- Original catalog note: HKS has released the MAX IV SP Coilovers for the Toyota GR A90 Supra. Designed for circuit driving and road coarses. Features: - This suspension utilized a conventional shock absorber rather than factory electronically controlled one and a vehicle easy to control according to the driver's intention. - Using the high rate spring provides a smooth ride without too stiff feeling and at the same time helps to translate a feedback from tires. - Adjustment type pillow upper allows to adjust the camber angle. - The billet aluminum upper plate is used at the rear. This is for weight saving without losing the necessary strength. - The straight wound spring is used at both front and rear allowing to easily change spring rates. - Spring rate [N/mm(kgf/mm)]/: F=137(14)/R=176(16) - Spring Length (mm): F=150(straight wound only) R=200(straight wound) - Upper mount: F=pillow/R=pillow Single Tube Damper
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
