There's a large portion of 818S builders running XXR wheels. These wheels are cheap. While there's not a whole lot of proof that their quality is so low that we're putting ourselves in danger, most "online" opinions suggest this wheel doesn't belong on the track. However the 818 is 1000-1500lbs lighter than most cars, and one could argue that we need less out of a wheel, or put less stress on it.
I've been very eager and indecisive this past week about ordering wheels/tires and need some direction. I will definitely be tracking and auto crossing my 818. Eventually I would like to have two sets of wheels/tires. A decent lightweight wheel with either R-compounds or slicks, and some street wheels(XXR) with some "high-performance" tires. But what I'm considering is running some XXR's with either R888's or NT01's and run just those for a few seasons.
Any thoughts on the subject? I welcome outright bashing of XXR's or either tire choice.
