Why not find something newer than 09 if your wanting to upgrade? You can find 2012 and newer chassis on here and facebook classifieds for around $1000 for just the chassis, sometimes less than that. I just picked up a 14 Impulse for $1300 that looked like it was new and only had a few races on it. Before that I had a 2011 impulse that I gave $1000 for last year, and a 2012 Shatter chassis that I had traded a few sets of tires for. You can buy a new Shatter chassis from Fast Action Karting for $2000, fully adjustable front end, split rear cassettes, braided brake lines, all the goodies that you see on most of the big name chassis like Prc or Millenium.
