Nissan GTR R35 — Rear Tubular Subframe — WAS-301
Our Nissan GT-R R35 tubular lightweight rear subframe allows you to drop the gearbox without ever needing to remove the subframe from the car again.
With almost a 50% reduction in mass, this subframe weighs just 34.94 lbs (15.85 kg), compared to the OEM subframe's 66.35 lbs (30.10 kg).
The rear lightweight tubular subframe is meticulously engineered, based on a 3D scan of the OEM subframe, fully CAD-designed, and rigorously tested using the Finite Element Method (FEM). It is constructed from T45 tubing (BS4 T45 to BS5T100 / BS6S100) imported from the UK.
The cross-member is completely TIG welded by hand, ensuring absolute quality control, using a special Lincoln Electric TIG wire that matches the tubing's tensile and yield properties. The removable middle connector is made from aircraft-quality 7075 aluminum and anodized for durability.
You can remove the gearbox from the car without removing the subframe, provided you use the Boost Logic Solid Transmission Mount Kit.
Features:
- Subframe weight: 34.94 lbs (15.85 kg), a 47% reduction and a 31.41 lbs (14.25 kg) saving over the OEM subframe.
- Constructed from T45 (BS4 T45 to BS5T100 / BS6S100) tubing and S355 metal sheets.
- All components are TIG welded.
- Delivered painted (powder-coated).

T45 tubing is a unique, seamless carbon-based steel tube used in various industries. It is stronger than 4130 Chromoly tubing, also used in motorsport. T45 is widely used in the aerospace sector in applications such as pilots' and crew's seats, due to its ability to withstand high G-forces without snapping or splitting. This material is carbon-manganese based and conforms to full aerospace specifications as laid down by British Standards. Properties for T45 are Tensile: 700 – 900 MPa, 0.2% Yield: 620 MPa minimum, Hardness Test: 201 min – 262 max HB or 210 min – 275 max HV. We also use S355 metal sheets in the subframe.
The dimensions of the subframe are 1412 x 886 x 295 mm (length x width x height).
Notice: Sold only for off-road, race track, and racing applications. If the buyer wishes to use the parts elsewhere, it is their responsibility to arrange the appropriate documentation. We strongly advise mounting the subframe in a qualified and experienced workshop.
