The car is very durable in my opinion . So far the only breakage for anyone was an outer hingepin . For setup the kit setting felt great on carpet I made some adjustments to better fit my driving style but out of the box it was great. If you are getting the R1 then no hopups are needed as the kit comes with all the necessary parts like any other high end kit. You might think of getting some dcj's . The kit springs work great for carpet but maybe look at getting the rsd spring set from reflex racing
