Sorry I red the wrong thing, I noticed at the HPI site the Pro4 had some cool upgrades, like the purple aluminum on transmission case, the camber linke thingy, is it worth buying? Also, i've got a TC3 as of now, i've been debating for a long time whether to get belt or shaft, and I decided to stick with shaft, also, whats the best shaft on-road car? My two favs were the Evo4 and the Pro4... What do you guys have to say? Also, i'm lookin forward to buying one if you guys have any extras..
