H&R Upgraded Spring Kit - Porsche 718 GT4 RS

The Porsche 718 GT4 RS is an amazing car, but those of us who push it hard have experienced a floaty front axle as well as rear-end instability, particularly during aggressive track driving. This is due to a slight imbalance between front and rear spring rates.

Over the years, GT4 RS owners who track their cars, as well as aftermarket parts providers came to a consensus: the GT4 RS needs a more cohesive spring combination between the front and rear axles. Slightly firmer in the front and slightly softer on the rear axle.

After benchmarking all the options available on the market and engaging with H&R tech specialists, we put together this premium H&R Racing Springs kit that deliver superior durability and handling. Spring rates feature a modest reduction in rear stiffness (from 140nm stock to 130nm) and a subtle increase in front firmness (from 100nm stock to 110nm). This combination was also recommended by Bilstein experts who extensively tested the GT4 RS on the Nürburgring.

Note: OEM suspension on the GT4 RS are manufactured by Bilstein for Porsche.

By aligning the rear springs more closely with the factory dampers, the erratic hopping is eliminated, allowing smoother control and predictability in corners. The firmer front springs also minimize braking-induced pitch, making the car feel more planted.

This spring kit enables a slight drop below the factory's lowest ride height setting, allowing for a more aggressive rake, while still supporting the original adjustable heights if preferred for street use.
