I'm actually kinda pissed with the change
I'm not sure about your regions specifically, but in ours, CS is slower than DS by a good 1-2 seconds. Even the ND Miata with an experienced driver.
DS has the Civic Type R, which is top dog in DS right now. 265 tires, 300HP. The Veloster N is another big player now too.
At our last event, the CTRs were getting a 41.8, Veloster low 42's. Top in CS? 43.8 ND Miata. Me in 175 run RE's... 45.1
Even with new tires, I think I'd be in the high 43's at best with the ND. There's a full 2 second difference on a ~45 second course with a CTR and twin.
The CTR is just 0.2-0.3 off AS times with hella good drivers. I think it's really a BS car at most. If anything, the BRZ both PP and non should be in CS with similar cars even though the PAX is worse than DS.
End rant on the CTRs. Our region now has 8 running this upcoming year. DS simply isn't the car for the twins at all now.
