The WRX at RBR is one of my favorite combinations. Even when it's not "good" there it's still a blast to drive. My biggest struggles are putting power down exiting 1 and 3. That's also where everyone else suffers too. So far my trick has been to have the TC menu up approaching 3 and flick up to 1 mid corner so that I can hammer the throttle and then immediately flick back down to 0. It's not great but I'm lazy and don't feel like feathering a controller
