While it's true that the Sport button drops water temperature 15-20 F, I don't think that makes it a must on track simply because I can't imagine that Porsche designed a system that would allow the engine to overheat unless the driver pushed a button; the more aggressive map is obviously forced on with Sport engaged, but that doesn't mean it wouldn't be triggered anyway based on running conditions if a need arose. Then again, I can't fathom why they decided to tie a thermostat map to an auto-blip function either. Even if this is a programming vestige from the non-GT 981 Sport button that controlled many more functions, I don't see why even those functions would call for a more aggressive cooling map. Why should the driver be given control of the thermostat at all?

No worries. If SPORT is not pressed, the car senses when you are driving hard and will open the thermostats automatically. If you press the SPORT button, the the thermostats will automatically open and stay open, no matter how you drive.

This is awesome. It's great to have everyone's thoughts in one place. Thanks so much.
I'm hoping to get a Cantrell bar and harnesses installed before the June BMW COTA event. I'm largely following in ShakeNBake's footsteps but I'll provide any additional thoughts/details once I get that done.

The first link under "caster bushings" should be this: http://www.tarett.com/items/986-987-...a01-detail.htm. The second link is already correct.

First, thanks so much for putting this together. It is an amazing resource and reference. Thanks to everyone who has contributed and especially to MyBailey.
A few questions/suggestions,
1) Do the 19" wheel options listed clear with OEM toe links, or only with aftermarket. I think clarifying this would be beneficial.
2) How does lowering the spring perches affect the ability to dial in more camber, and at what point (how many turns) does lowering make caster a concern. Is there a standard number of turns for the perches that would allow more camber without adversely affecting caster?

Great questions.
As far as the 19 inch options, I know the 10.5 rear wheel should clear the oem toe link without problems at around 44 offset and can easily run a 295 tire. I can't personally confirm whether the 11 inch clears oem links, or not; however, I seriously doubt whether it will from having seen the minimal clearance on aftermarket links.
Hopefully some others will chime in an confirm this, or correct me.
As far as your second question, to be honest, I don't know for sure and don't want to mislead anyone. Can someone with more knowledge than I answer this?

The front 19x8.5 OZ's have 53mm offset and don't need spacers. They clear steel brakes, but it's tight as well. There seems to be sufficient clearance around 245/40 RE-71R's.
I'll know in a couple of weeks how the car behaves at the limit with an aggressive autocross alignment.
