Okay, so im looking at ACT Clutch kits and I have a few questions. There is one kit that uses the 6 Pad Race Disk, then there is another kit that says it's the performance organic street disk. Which one is better to have? My SI is my daily driver/street racing car. Also, what is the difference between a heavy duty pressure plate compared to the Xtreme Pressure Plate? Any advice on this would be greatly appreciated. Here is the website to where I'm getting this info.
