Yeah, use the Xray shocks and nothing else!
Take your time building them and if you have questions post them in the T2 section thread and someone will reply. Take your time building the diffs and follow the instructions carefully. You might want to prep the chassis edges by sanding them a bit and rounding the edges if you run on carpet. Sand them and CA the sides and you'll have a nice finsh if you do it right. You also want to file the battery slots in so your cells fit nice and snug. Setups are online at http://www.teamxray.com
under the setup section. Hope that helps.
