T1R - S-Coil Progressive Lowering Springs - Nissan Skyline R35 2009-Up

The T1R coil-over spring kit features fully ride height adjustability while maintaining the factory electronically adjustable suspension. The factory shocks are very well built so it is not necessary to upgrade but we found the factory springs are too soft and it causes a lot body roll and understeer. We uses stiffer springs to reduce body roll when cornering and reduces nose dive under under hard braking. With this setup, the car will be easier to control and appears less understeering.

Besides lowering the ride height, you also have the ability to adjust corner weight balance to ensure all shocks have the same amount of stroke and shock travel. As a result, handling will be significantly improved. We have track tested our GTR with this spring kit and from the result you can easily shaved off a few seconds at the track.

This kit comes with pillowball (spherical bearing) uppermounts. This is to increase the suspension feedback by eliminating deflection from factory rubber bushings. The mount is made out of Forged A2017 aluminum for weight reduction and durability.

The Spring sleeves are made out of CNC machined chromoly steel with rust proof coating against corrosion. We offer bolt-lock type spring perches (single) for easy adjustment. The spring perches are made out of CNC machined forged A2017 aluminum to handle high stress and quality assurance.

Coil-springs are made with cold forming process and it meets SAE standards. Special designed tapered shape to increase shock travel and to reduce binding. The T1R kit comes with F.18k~20k and R.14k (+/-)2k (kg/mm).

Competabe with Asian, European and North Americans GTR R35.
