the x11 an amazing car... it is very easy to work on and a pleasure to drive.. and you get way better quality parts when you get the x11.. and all of the updates on the car alone is well worth the extra money.. just trying to convert the xrs to x11 spec will put you well over the price of an x11 kit.
my advice is save alittle more and go for the x11 it is the same car that the team runs and you will be alot happier performance wise as well as strength..
hope this helps.
