Rob, I fitted in an Elise fine, but struggle in the strat with crash helmet and head room, fine without a helmet and a standard seat. The roof line and curve in, is so severe on the strat and with a the roll bar it makes it a little tight on the head , im 6ft 1. Knees also a tad close up around the column with a full bucket seat. One of the few times I wish I was short. Theres no way im not driving it tho, I will adapt, im sure a few rally boys have had to too.
