The standard width Corbeau Revolution System 1 in Tartan Edition trim, at 920. FIA 8855-1999 fibreglass, fixed back, head support, wool tartan and velour.
920 here, 960 in XL
Forty pounds between the two, so choose on width rather than budget. The XL is cut for larger hips and ribs. If the standard shell fits, use it, because a bucket works by holding you still.
Where it sits against the Revenge
The Revenge System 1 Tartan is 875 and this Revolution is 920. Both are FIA shells with head support in the same wool tartan. The 45 between them buys a different shell shape, not a better seat, and which suits you depends entirely on your build.
The tartans
Eight to choose from: Blair Ancient, Boyd Modern, Earl of St Andrews, MacFarlane Clan Ancient, MacKenzie Dress Modern, MacMillan Old Modern, Stewart Dress Modern and Weir Ancient. Each seat is trimmed to order in that cloth, so tell us the design when you buy.
Mounting and approval
System 1 is the fibreglass shell. This seat is base mount rather than side mount. FIA 8855-1999, with the seat’s own label carrying its validity rather than any general rule.
Not included
Frames and mounts. Send us the car and we will confirm what completes it.
