i suddently had this thought in the middle of the of my english class this morning.........does aero kits really help?, like a side skirt and a huge bumper that are like R34.....do they really work?...like makes ur car not drag as much or something?.or is it just for cosmetics...??...and.,,,i forgot what i was gonna say.......

...ohh yeh i remember.......how does blow off valve work?.....does it have a automatic swtich that opens up when the RPM goes down and the pressure decrees?.....thx...
