Hi Brian,

Would you ever consider designing an NC header with a high flow cat in it if STR proves to be very popular?

Hehe, understood Brian, thanks for taking the time to respond!

Wow, glad to see so many people excited about this class. So do you think the +45 offset is ideal, there are a few other choices at:

+43: 5Zigen FN01-RC
+46: Konig Runaway (only 8" though)
+49: Weds TC-105N

The +49 might be nice if it doesn't rub on the inside. Thanks guys!

Note you cannot change the midpipe for stock class autocross on 2006 or newer because the NC generation has a converter in the factory midpipe. Brian, I'm interested in the RS midpipe/header, but I'm kind of confused by the wording in the solo rulebook section 14.10D/E...I know the NC is not curren...

Brian, does Ohlins offer 5kg springs for the rear, or other optional spring rates?

Hi Brian, This might have been asked before, but I didn't see any threads on this. Since the NC's suspension is very similar to the RX-8's, is it even remotely possible that oem/oem style aftermarket springs (i.e. Eibach/Racing Beat) springs for the RX-8 can fit the NC? I'm pretty sure it won't be a...

Uh...sorry for this off topic post Brian, but I have to ask, are those 225/50R16 Azenis mounted on your stock 16's? They look incredible...
