Now that looks fantastic, professional , efficient , and about 20 more adjectives I could throw out there! It gives me , and likely a lot of others, an idea on what we should be doing to modify our setups?!
The stock cooling with stock (or GiroDisc) rotors is very good, under most conditions at most tracks. The exception is extended trail braking after a hard braking zone (e.g. VIR or Road America). The symptom is grooving of the front rotors, caused by hot spots.

The lighter, smaller, AP rotors have less inherent heat capacity, and benefit more from directed cooling.

I believe for the stock set-up there will be a rotor and pad life benefit for those who are hard on brakes at brake hungry tracks with the addition of directed brake ducts. I view them as mandatory for race/hard track use with the AP set up.

May seem like a small item to some , but glad you mentioned the diff seals needing replacement as this is a very common occurrence with alot of modern ,independent rear end vehicles. Good item to have on hand for many when replacing or upgrading , imho -- thanks for posting this.

How're you liking the ARH headers with the OEM mufflers? Any desire to add their mufflers to the system?
The car is very loud, way louder than my Boss with Headers, open side pipes and Corsa Mufflers. It may be that the carpet/trim/headliner in the Boss is the difference.

Earplugs are mandatory for track use in this car....

I'm going to stick with the OE Cold end exhaust, it flows well, even if it is a bit loud with headers.
