TTX High End Coilover Suspension Nissan GTR R35

your high-end inventory at Buy Mustang parts Ltd, the Öhlins TTX (Twin Tube Technology) coilover system for the Nissan GT-R R35 is the absolute pinnacle of suspension engineering. Unlike the standard “Road & Track” series, the TTX line is a dedicated motorsport-grade application designed for serious track competition and elite tuning.

As of 2026, this kit remains the gold standard for GT-R owners who have outgrown factory electronic dampening and seek professional-level chassis control.

1. Core Technology: The TTX Advantage

The “TTX” (Twin Tube X-Flow) design is what sets this apart from every other coilover on the market.

• Pressure Balancing: The twin-tube design ensures that the internal oil pressure is always balanced, which eliminates cavitation (the formation of air bubbles in the oil) even under extreme, high-frequency track use.

• Integrated Reservoir: The TTX36 / ILX36 dampers feature an internal or integral reservoir, making them incredibly compact for the R35’s tight suspension geometry while providing superior cooling.

• 4-Way Adjustability: This is the “Pro” feature. You have independent control over:

  1. Low-Speed Compression

  2. High-Speed Compression

  3. Low-Speed Rebound

  4. High-Speed Rebound

2. Technical Specifications (Kit NIR GN00)

This is the most common high-end configuration for the R35 GT-R.

• Spring Rates: * Front: 260 N/mm (Approx. 1485 lbs/in) — Extremely stiff for precise turn-in.

  • Rear: 150 N/mm (Approx. 856 lbs/in) — Optimized for the GT-R’s rear-biased weight transfer.

• Ride Height: Typically delivered with a recommended drop of 20mm lower than standard, but fully adjustable.

• Top Mounts: Includes Uniball Aluminum top mounts for zero-deflection steering response.

3. 2026 Market Value & Resale Strategy

This is a “Boutique” item. It is not for the average street driver, and your pricing should reflect its rarity and performance.

4. Strategic Advice for Buy Mustang parts Ltd

• The “EDC Cancellation” Necessity: The R35 comes with factory electronic dampening (Bilstein DampTronic). Installing TTX coilovers will trigger a suspension fault on the dashboard. You must bundle or recommend the Öhlins EDC Cancellation Kit (Part #35020-06). Selling these together as a “Fault-Free Track Kit” is a major value-add.

• Linear vs. Progressive: Highlight that these use Linear Springs. While this makes the ride much “busier” on the street, it provides the predictable, mathematical handling that professional racers require.

• The “Build to Order” Hook: Most retailers have a 4–8 week lead time for TTX kits. If you have this in stock, emphasize “Immediate Delivery”—luxury clients will often pay a $500+ premium to avoid waiting for a custom build from Sweden.

5. Quality Control & Inspection

• Shaft Inspection: Check the 36mm piston shafts for any “micro-scoring.” Even a tiny scratch can tear a seal under the high pressures of the TTX system.

• The “Golden Knobs”: Ensure the adjusters (the gold and black knobs) click crisply. If they feel “mushy,” the internal detent ball is likely stuck or corroded from salt/grime.

• Salt Spray Integrity: These are ISO 9227 salt spray tested, but if you are buying from a coastal or “snow belt” region, check the threads for galvanic corrosion between the aluminum body and the steel spring.
