CC's online shop is pants for newbie . I sometimes wonder why people buy these cars when they so regularly criticise both the Caterham shop (usually it's expense) and Caterham components (radiators, OPGs, senders, etc). If you are not sure which bit you want, Nigel, give them a call. My experience is that they are extremely helpful and reassuring.
I run most of the time without side-screens, but with wind deflectors. It must take all of 2 minutes to take off the side-screens and fit the SVA mirrors - which are good and effective. But as for side-screen storage if you want to change back when away from home? If you have a solution, please share it.
