LouisB: The Big Bores should be just fine with the Pro-Line suspension kit!!!! As for the CVD's I recommend but you might be able to get my with stock for now, check out Dynamite they have set of cheaper CVD's than MIP, that should be just as good also they have CVD's for the Driveshafts for the same price $37.99 versus $55.00 from MIP, just go to www.horizonhobby.com & for name brand put in Dynamite then Nitro truck & car & search through there, it's in there some where!!!!!!
