I ordered the 25mm because of others recomendations, and i couldn't be happier. For me it took a little extra time to install because one of the original bolts snapped. But pretty easy install and the results are amazing. My 2000 SE has an upgraded ECU and Downpipe, and JT Exhaust and Bsr intake and it was a handful in the first two gears, but now it puts the power down really well, with almost no tug at the wheel. I cant believe i waited so long to put this on.
