Utilizing the same T45 tubing found in WRC cars, these subframes provide increased stiffness, reduced weight and more precise handling.
Benefits
- 6.5 kg lighter than the standard rear subframe. That's 33% less weight on the rear axle of the vehicle!
- The rear final drive gear has been shifted 10mm upwards to reduce stress on the joints.
- Removed the rubber mountings of the rear subframe to the body and made only one mounting point.
- Additional steering adjustment on the subframe.
- Rubber mounts for the rear final drive have been replaced with black polyurethane mounts.
- Significantly more space for access to the underside of the vehicle.
- Increased chassis rigidity due to tubular frame construction for improved handling. Manufactured from T45 tubes (BS4T45 - BS4T100) imported directly from the steelworks and S355 metal sheets.
- Designed, manufactured, inspected and tested in Poland. Each manufactured part is checked by qualified personnel. Welds are checked for cracks and the entire product is inspected before shipment.
- Great appearance.
What's included
- Pre-assembled rear subframe powder coated black.
- Set of steel adjusting shims (24 pcs.) for lever positioning (allows steering adjustment) (-5/ -4/ -3/ -2/ -2/ -1/ -1/ 0/ 0/ 1/ 2/ 3/ 4/ 5 mm).
- Set of tie rod bolts and nuts (galvanized, class 10.9).
- Set of steel adjusting spacers (8 pcs.) for setting the camber arms (-3.5/ 0/ 3.5 mm).
- Racing polyurethane mounts for rear differential.
- Exhaust system mounting bolt (galvanized, class 10.9).
- Printed installation instructions.
Important information
T45 is a unique seamless carbon steel pipe that is used in many industries. It is stronger than Co-Mo 4130 pipe, which is also used in motorsports. It is widely used in the aerospace sector in equipment such as pilot and crew seats, due to the material's ability to withstand high G forces without seizing or splitting. This carbon and manganese based material meets all aerospace specifications set by British Standards.
T45 properties:
- Tensile: 700 - 900 MPa,
- 0.2% yield, minimum 620 MPa
- Hardness test: 201 min - 262 max HB or 210 min - 275 max HV.
Replaces:
- 33316794865
- 33316795830
- 51206WAA04
- 51206WAA05
Note: An adjustable tie rod must be used to set the correct tilt angle, as there is no adjustment on the subframe (replaced by a bump steer).
