Nissan GT-R R35 suspension: Bilstein + H&R

inventory at Buy Mustang parts Ltd, the Bilstein + H&R combination is the most popular “Street-Plus” suspension setup for the Nissan GT-R R35. This pairing is often preferred by owners who want a more aggressive stance and sharper handling without the high cost or maintenance requirements of a full motorsport coilover system.

1. Component Synergy

The R35 comes factory-equipped with Bilstein DampTronic dampers. When customers ask for this setup, they are usually looking at two paths: swapping in new Bilstein B6/B8 dampers or simply adding H&R springs to their existing OEM Bilstein units.

• Bilstein B6/B8 DampTronic: These are designed to integrate perfectly with the GT-R’s factory “Comfort/Normal/R” cockpit switch.

• H&R Sport Springs (Part #28989-1): These feature a progressive spring rate, meaning they remain relatively compliant during normal cruising but stiffen up significantly during hard cornering to reduce body roll.

3. Strategic Advice for Buy Mustang parts Ltd

• The “CBA” Refresh: Owners of early 2009–2011 (CBA) models often find their original Bilsteins are beginning to leak or feel “tired.” Marketing a “Complete Refresh Kit” (New B6 DampTronic Shocks + H&R Springs) is a high-value upsell for these customers.

• Alignment Warning: Dropping the R35 by 30mm will naturally increase negative camber. Advise your customers that they will need a professional alignment post-installation, or offer Adjustable Rear Camber Arms (like SPL or Whiteline) to prevent premature tire wear.

• The “Nismo” Exception: Note in your catalog that H&R Sport Springs are typically not recommended for the Nismo R35, as the Nismo uses a specifically valved Bilstein setup that does not pair well with the H&R spring rates.

4. Inspection & Quality Control

• Spring “Pig-Tail” Check: On used H&R springs, inspect the ends (the pig-tails) for paint chipping. If the powder coating is gone, the spring will eventually rust and “snap” under load.

• Shock Actuators: If you are selling used DampTronic shocks, ensure the electrical connector pins at the top of the shock are straight. If these are bent, the car’s computer will throw a “Suspension Malfunction” code immediately.

• Dead Coils: Look for “coil slap” marks on the springs—this is where the coils have touched under compression. If these are present, the springs may have been used on a car that was too heavy or driven too hard.

5. Logistics & Shipping

• Weight: A full set of 4 shocks and 4 springs weighs approx. 28kg – 32kg (62–70 lbs).

• Protocol: Ship in two boxes to stay under standard weight limits and prevent the heavy shocks from crushing the springs.

• Protection: Use expandable foam packaging for the DampTronic shocks. The electronic actuators on top are extremely sensitive to impact during shipping.
