as far as the geometry of the rtr it is the same as the cr and will handle similar to the factory team edition unfortunately the materials used for chassis and shock tower will bend very easily and will need to be replaced, the cost to convert this car to a factory team is more than the price of a factory team buggy.
if you want to race you will find out that going the rtr direction is the most expensive way into the racing side of the hobby. as many on this board who have started can tell you. if your plan is to race you will be better off going the used route and buying good servos and a radio, then i would suggest a good beginner engine like the o.s. rg until your ready for your v-spec. if you search ebay you will be able to find good used pro level kits. or you may want to go to the track and buy from a local racer, things that are expensive on the kits like shock towers and carbon fiber, will last a long time after you have the car and the parts that wear will be cheaper to replace. instead of having to upgrade the expensive parts.
a little more money now will save you a lot in the long run.
