Hum... looks like someone traded his 15% for a 19%...

How do you like it?

I did the move 2 weeks ago and love it!

 

Exactly right. 19% is more fun than the 15%, for sure! I kept the 15% for a while, but decided I wouldn't go back, and selling it would offset at least a little of the latest acquisitions: exhaust and camber plates.

 

oh my god, you're going to blow up your supercharger! the coating will come off the rotors, you'll over-spin it oh my god blah blah blah. Enjoy that 19, free bump for you! Someone take the pulley, best upgrade for the money.

 

Sold!
