Hi Phil,
I've always had my doubts about the NVH kit (especially after being told by someone at the factory that it was 'a waste of time')! Therefore, I'm definitely interested in your BB mounting kit. Am I right to assume that it can be retrofitted without removing the engine? Personally, I'm not so interested in the Centa poly blocks because my stock Centa isn't causing me any concerns since fitting the G56 exhausts. This situation may change if shreaded rubber starts to appear under the car at some point in the future!
Thanks,
