Matey I know of a good Pro 4 that could be set up well for drift, I see that you already have one so a second wouldn't go astray for spares if need be, they drift quite good as well. It is a mate of mine and he only raced it for half a season, it has been for sale for quite a while so make him an offer. Here's a link to some pics
http://www.rcracer.com.au/forum/viewtopic.php?t=2950 . His number is on there so you can call or SMS, him if you're interested or PM me and I'll pass it on.
