I saw an advertisement for these sleeves and have never heard of them before. Some interesting claims being made. More interesting is they are appearantly available for both the C30A1 (NSX 3.0L) and the C32B (NSX 3.2L) in the article I found, but no mention is made on their website .
Any one have experience with these or any opinion on the design versus Darton's?
