IMO shift-knobs aren't worth ish... seems like a waste of money... doesn't really do anything... every ricer has one... nothing special really.... save that money... do the MoDs listed in my sig... there are a couple mods out there that cost near nothing if DIY and IMO are more worthwhile...

1. take out the resonator and replace filter with k/n drop in... sounds alot better... works as a ghetto (effective) CAI...
2. drop you can get some sh1tty springs for 100 or get some good ones for under 200
3. (if not already painted) paint mouldings and side skirts
4. black housing headlights. DIY all you need is oven black spray paint and silicone (total assuming you have an oven: $5 and IMO they look bad ass)
