Yeah i would think too that it might be their setup or their personal opinion of the car...i have heard that its lighter and from what i have seen from the parts it is built stronger...they really thought about weight and im sure it would be worth it to convert this vehicle if you have the money to throw at it...or slowly buy the parts and put them on the vehicle until u would have to buy the chassis and probably the drive shaft +3mm when you need to do that! Other than that...battery tray and diffs are the same...no changes made...i am happy that they made a new wing and have the jconcepts body on there...cause it did make a difference in my book! I would look for some setup sheets from the pros and see what to do then!! Thanks for posting !
