ID.3 / Cupra Born
Rear Body Brace
During our R&D programme on MEB-platform, we've learned that whilst the body is very stiff and well reinforced around the floor area that contains the battery pack, the upper body is not so rigid.
So, our beautiful Carbon Fibre Rear Body Brace tightens up the weakest point on the car between the rear suspension mounts.
The result? Sharper dynamic responses, with no compromise.

Modern electric cars like the VW ID.3 and Cupra Born built on the MEB-platform have a pretty stiff laser-welded bodyshell.
Up front, the MEB chassis is very rigid between the suspension tops, but at the rear there is much more chassis flex which negatively affects vehicle handling in cornering. It's bodyshell flex that gives the creaking you occasionally hear.
The new RacingLine Rear Body Brace solves this issue by locking the crucial hard points together. It uses solid billet aluminium mounts secured into the beautiful, ultra-stiff carbon fibre link bar drastically stiffening the rear of the chassis.
By reinforcing and tying the rear strut towers together, the brace helps to maintain proper suspension geometry under heavy cornering loads. Remove the bodyshell flex, and the suspension geometry can work as it was designed to do.
Despite the added stiffness, this improved handling performance comes without sacrificing any ride quality or introducing any additional noise, vibration, or harshness into the cabin.
Thin, low-profile design means minimum impact on boot space and no effect on rear seat operation, up or down.
Clever design means fitting is quick and simple. Completely reversible without trace for removal.
No cutting, no drilling needed. By cleverly re-using the strongest parts of the body, there's no need to modify.
You'll immediately feel the sharper dynamic responses with the Rear Body Brace fitted. That translates into tighter handling feel as the suspension geometry is at last able to work as it should with less of the 'squidge' that comes from chassis flex.
You'll even notice the difference at lower speeds. Manoeuvres such as turning into steep-approach angled ramps or driveways also cause the body twisting moments that lead to creaking trim.

Best of all, the clever design means that installation is simple.
By using existing body mounting points, there's absolutely no cutting, drilling or removal of trim needed to install. Meaning that fitment is fully reversible, and takes up minimal boot space, thanks to the low-profile design.
