LIGHTER & MORE STABLE

After a long CAD development, based on 3D scans of the original subframe, you now have the opportunity to upgrade your BMW Z4 G29 with a brand new, rustproof subframe for the rear axle.

The axle carriers are made from T45 tubes and S355 metal sheets, which are also used in rallies. These offer increased rigidity and an enormous weight reduction. In addition, they were designed in such a way that access to the vehicle underbody is made significantly easier. 

A whopping 6,5kg lighter than the Original Equipment rear subframe, that's 33% less weight on the vehicle's rear axle. The rear final drive has been moved up by 10mm to counteract premature wear of the joints when lowering.
The rear subframe's rubber mounts on the body have been removed and modified to bolt directly to the chassis through smaller mounting holes. This is to prevent the frame from shifting under heavy loads.

Additional bump steer adjustment. The rear final drive rubber mounts have been replaced with black 85ShA PU mounts which prevent the gearbox from moving under torque (which the factory rubber mounts do).

EASY INSTALLATION

The frame is easily fitted to the bodywork, all original parts can be plug and play attached to the new subframe, which means that no further modifications are required. The original wishbones can also continue to be used.

ALSO AVAILABLE IN YOUR FAVORITE COLOUR

You are free to choose from the entire RAL range! Simply specify the desired RAL color when placing your order. The default color is black. Another color costs €50,00 extra.

T45 is a very unique carbon base seamless steel tube that has been used in many applications across various industries. It is stronger than Co-Mo 4130 hoses, which are also used in motorsport. It is widely used in the aerospace industry in equipment such as pilot seats and crew seats because the material can withstand high G-forces without cracking or chipping. This material is carbon manganese based and conforms to full British Standards aerospace specifications.
