Hard to make up my mind on the shell, everyone I like is always out of stock, so I think I may go with an hpi one, something like the gtr http://www.hpiracing.com/en/part/17538 , or the supra http://www.hpiracing.com/en/part/17539, I read I have to use wheels with a bigger offset to fill the 200mm shell, seems easy enough.. i do like the s2000 too http://www.hpiracing.com/en/part/17506
