Further excellent work in solving the conundrum of many different specs offered by Caterham over the years, popular modifications to those cars all distilled into 6 or 7 easy to comprehend classes Whilst it clearly does not directly affect me my only question is the choice of 220BHP for the class break. As 210 would cover the current 420 model and many of the R400 type models from the past is there a particular reason for this. I know it is only 10bhp but you know how competitive we all get so if there is not a good reason it just seems to open the door to competitors feeling obliged to upgrade to be competitive Grahame
