Steve, 'i did find a few road that challenged the bar under the gearbox though' I know what you mean. I bottomed mine out regularly on my previous CSR, especially on the Helmsley TT road that Ged mentioned. On my current 2012 CSR, I notice Caterham came up with a 'fix' for that, they removed the bar. I don't know if they added anything to compensate or just removed it. Cheers
