#21R also received a specially modified roll cage to make sitting in that passenger seat just a bit more comfortable. Check it out...

Although the standard Mclaren F1 is a three seat car the GTR variant for racing retains only the central driver's seat. The standard roll cage uses part of the space normally allowed for passengers. The current owner of this car wanted to be able to carry passengers occasionally and to be able to race. The right hand seat space is taken up with electronics which could not easily be moved so ARRC were tasked with designing a new cage which would allow for passengers in one form and revert to racing layout in the other.



This picture taken part way through the build shows the "passenger" version with the upright bar absent and a wider spaced back brace to allow for the passenger head and shoulders. The racing variant looks more like the other side with a straight back brace and an upright. Changeover involves undoing a few bolts, swapping tubes and replacing the bolts.
The front bars from the main loop forward and then down by the a-pillars are not fitted in this picture.



Details of the mountings which bolt into inserts in the carbon fibre tub.
