Not all all, I think that is what a discussion board is all about. Like most mods in everyday driving you are right-there is really not a whole lot of difference. I doubt if most people would even notice it. My past cars have always seemed to run just a bit better and cleaner on 93 and the Boxster in particular seems to run smoother. Like all mods though I think it will only make a difference under extreme circumstances such as REALLY spirited driving or track/autocrosses. You mentioned 2.2%. My last boss (and mentor) once asked me if I knew the difference between a race horse that won a million dollars a year and one that only won one hundred thousand dollars a year. I thought about it for a second and admitted I did not know. He told me the difference was 1%. I asked how that could be and he replied "because that's all it need to be-just a nose, 1%. So while I know I won't be blowing away any 987 S's, chasing Carreras down the back straights and I will watch Corvettes tail lights pulling away from me at a speed which I could never match I believe that all these 1 & 2 percents add up and can result in a much better driving experience. Not only that but if I come across an unsuspecting 986 I can smoke him!

Just my .02 or was that .08?? Sorry for the long reply!!

I think there may be someone else out there who may have a better understanding of the differences and might explain it more clearly. Anyone???
