Vr4 owns joo meant that his rpm drops quicker from the lightened fidanza flywheel he's got. Think of it this way, once you spin a nice heavy top, it spins forever, on the other hand,spin a lighter top and it will slow to a halt much sooner. That's why a lightened flywheel revs quicker and decelerates quicker when you lift the fuss vom gas, the stockers rev slower and hold the rpm longer. To each his own.

with no spanner wrench holes taking one off is a PITA but the quality and certainly support from them guys is second to none.

I will be running a few on a lathe by the end of the year...but for the money...get the 3sx one NOW

I have had mine on for 20,000 miles now no problems... its the perfect match to my lightweight flywheel. I think downpipe and crankpulley are the most bang for your buck items i beleive.

I'd definitely get it, if I were you. I bought mine and it's really good. I'm not too sure about 15 to 20 HP gains, but there'll be some. I felt it on mine.

I've also had mine on now for a good 15-20,000 miles with no engine problems. I did also come across the a'c belt squeeling while running. I came to the conclusion that (at least on mine), the tracks that the belt rides on were a little closer to the engine than on the stock pully therefore it stretched the belt to the side a little while running and would squeek. Not a big deal though, I played with my A/C tensioner pully a little bit and it's seemed to have gone away. I'd definately reccomend it though
