The Skyline GT-R's suspension is already serious engineering. HICAS rear-wheel steering, purpose-built multi-link geometry, ATTESA ET-S all-wheel drive — the factory put real thought into how this car handles. So when NISMO develops a suspension upgrade for it, you pay attention.

The S-tune Suspension Kit for BCNR33 and BNR34 is one of their benchmark products. It's an assembly-type coilover system — meaning you replace the complete strut assemblies front and rear, not just springs or dampers separately. Five-stage damping adjustment front and rear, with the front units using a remote reservoir tank setup.

What the numbers actually mean

Front spring rate goes to 58.8 N/mm (6.0 kgf/mm), rear to 65.7 N/mm (6.7 kgf/mm) — firmer than stock but calibrated specifically for a car weighing over 1,500kg with twin turbos up front. Ride height drops approximately 30mm front and 20mm rear, which lowers the centre of gravity and measurably reduces body roll in transitions. Not just stance — actual geometry improvement.

Five-stage damping gives real tuning flexibility. Run it softer for long-distance motorway driving, firm it up for circuit work, find a middle ground for mountain roads. This is how a serious suspension setup should work — not one fixed setting trying to be everything to everyone.

Availability note

NISMO currently lists this kit as discontinued for new production (part number 5300S-RSR45). That makes finding a genuine complete set a question of specialist sourcing. But understanding what this kit is and what it does is essential for anyone building a GT-R and thinking about suspension direction. A used, genuine S-tune set in good condition is absolutely worth hunting for.

One installation note: adjusting rear damping on BCNR33 and BNR34 requires cutting access holes in the parcel shelf. If you have aftermarket rear speakers, factor this into your installation planning.

For any GT-R owner who wants manufacturer-calibrated suspension improvement — not just stiffer springs — the NISMO S-tune is the reference point everything else gets measured against.
