Tire/insert break in may be the issue. Like others have mentioned, bar style tires need to be broken in. The PL CC inserts are very stiff when new, and take a good while to hit the sweet spot. You can speed up the insert break in by saucing the tires, wrapping them in Saran Wrap, then placing them in a Ziploc bag. Do this at least 3 days before your next race. Let them sit for a day in the bag, then put them back on the car and let them breathe for a couple days. The Saran Wrap will force almost all the sauce into the tire. The more sauce the tire absorbs, the more the foam will absorb. The more the foam absorbs, the more it will break down/in. Be careful, as too long with the Saran Wrap and the foam will be too soft. And not letting the tire breathe for long enough will make the rubber too soft. Also make sure wherever the tires are sitting for the post-marinade breathe is a "smell isolated area" as to not upset anyone else in the household.

Bro Codes?

You're right, the rear hubs are not red. I know when doing a one off build like that it is as much about the hunt for parts as it is the end result. If it were me, I would have just done the parts that were normally FT blue, and had everything else black or raw aluminum. But like I said before beauty is in the eye of the beholder.

If something is an opinion of mine I usually will not beat everyone over the head with it. If whatever I am stating is a fact, and nobody else has posted what is clearly the fact, then I am not so subtle. Case in point, Kellens post about the tires taking a long time to break in at WCRC. My factual response is to run the new pre-broken in Bro Codes. That or bust some sweet donuts in the parking lot (which others have mentioned).
