Rockers seem to be the consensus so thats what I'm leaning towards. Yeah I know tuning is crucial. After a quick internet search XP-racing seems to be the only place around here thats worthwhile but a tune is $450! Thats more than twice as much as an Overkill after the core charge. Would it really be that much better? I guess I could afford it but Id rather not have to lol.
Thanks for the input guys!
