INSANE build from Six Star Auto / Prime Motoring in the Kartboy booth this last weekend at Wicked Big Meet - from all the JDM goodies to the ridiculous power figure controlled on a Haltech - Jason’s 98 RS was one of the sickest cars on the property.

You can FEEL the slop already, but we wanted to SHOW you what it actually looks like. This is what’s causing that uncertain feeling in your shifts. The OE joint did a good job many years and miles ago but we didn’t want to settle for “good enough.” The Kartboy solid shift joint for 5 and 6 speeds is the final boss of tightening up your shifts and is available for pre-order at a 10% discount until June 15th. Grab yours today, wiggle it side to side, and imagine what a tighter shift could feel like.
