Stand 21 RS-2 20° FHR collar, perfect for the Clubman through to the Professional driver. The advances in design, technology and manufacturing process have created a device that is only 200 grammes heavier than the much more expensive Hi-Tech full carbon fibre model, yet 30% lighter than the, less comfortable Sport model and all for only a little extra money.
The RS-2 model has surpassed the FIA testing requirements, it's hugely more comfortable to wear due to the design changes, the harness location and fitment is more positive and it comes with sliding tethers as standard. FIA 8858-2010 Approved.
