i would steer clear of the mini inferno i have one in the top of my closet that icant get rid of due to the amount of money i have spent try to make a decent car out of it. the bolts that hold the knuckles and the liitle spacer they go in is a very week link even with aluminum knuckles and titanium ferrals(tiny spacer they still come apart even with threadlock. either one of the others will serve you better in the long run.
