Ok looked at exploded parts view of v3 and there are only about 5 new parts. Mostly axle related. Everything else is same as v2. Not sure why they would call this v3. Could have been a running change v2. But I guess it may sell some more kits if it appears to be new. $250 or even less with coupon codes is a steal for this v3 though. Hope plastics didn't change.
