Well guys if uve read any of my posts I've been working on my conversion truck, its the 2.5 with ALL the 4908 upgrades, all that is left on the whole truck that is 2.5 is chassis and the chevron wheels n tires..oh and the body too. And... Well this bad boy will haul tail. Its mean, like crazy fast. I'm very impressed. Lol well here's the thing, it seems to only hook up good while I'm in the grass, and it'll do wheelies as far as u could see,but on pavement it seems to do nothing but blow the tires, it spins and drifts like crazy it has a lot of power and I was thinking would it be best to just finish my conversion with the newer 6.3 wheels n tires? Maybe the newer chassis? I really don't wanna go that rought considering, I have already got a set of 4949R center cvs for my truck and they only fit the short chassis. But if I did get the extended I don't want dogbones at all. So would it be a good/ less spin option if all I did was get the bigger wheels? Would they do just as good in the grass as the old chevrons, but better on the road? Please comment. Thanks
