Outstanding post, nolimits! Great feedback.
When you get a chance over the next whatever period of time, can you please dive in to more specifics about the suspension mods? Which bearings, which arms, which spacers, which camber plates, which links? Stuff like that. We're down to fine tuning, so more detail is better.

Rennline mesh grille guards
OEM PCCB rotors with OEM GT3/RS pads
AWE mirror wind deflectors
OEM 991.1 TTS shock/spring/sways
Tarett sourced:
-Front monoball camber plates for stock style shocks
-Front cup series lower control arm (LCA) kit
-Front Litronic sensor support brackets, GT3 style
-Front tie rod bump steer toe links, motorsport/pinch bolt locking style, easy adjust, don’t come loose or contact other parts like some locknut type links do
-Front axel spacer kit 10mm
-GT3 LCA shims
-Front lower control arm spacers GT3
-Rear long upper control arms
-Rear medium upper control arms
-Boot ends (large)Ira at Tarett was great to work with for parts, check with him for your specific goals/situation or his PNs/quote.
Most bushings are monoball, ones left OEM (I think they were the front LCA's) will need replacing much sooner than mono’s because they are not designed for the loads from this config. I’ll do full mono probably at that time and soften the DSC street settings some to offset, leaving Sport + taught, and yes edgy/knifelike as is. Not full out race car config feel, but exceptional track/street hybrid dual use mode set-up.
-DSC V2 controller, much custom tuning myself
-Sharkworks catback exhaust, otherwise OEM powertrain
-All 20”: 2 sets OEM wheels for PZeros 245/305, and C2s 265/325, 1 set Forgeline for R7 265/335 or Trofeo R 265/315
Alignment in degrees, or close targets for me as able:
Front – 3.4 camber, 9.2 caster, 0 total toe
Rear – 2.9 camber, 0 thrust, total toe .26 (.13 per side)
I keep rear toe minimal because I feel rear steer works well as is, if car was RWD and FWS this would be much different. Car not lowered so I can use soft DSC street settings and have suspension travel. DSC sport + set-up is firm. Camber and caster config does lower car some as a byproduct.

Ya they've done some good things with Mikes car and expensive weight loss carbon as you know. I'm looking foward to adding power next. Gotta get my lift wired and set-up now.

How do you like 265/315 Trofeo R? Any times compared to Hoosiers or Cup2 265/325?

Haven't driven them yet, will have to wait til temps warm up here in spring, curious also on times too, expect them to be right in between above C2 and R7s.
#186
What is the time and feeling difference between C2s and R7s for your car? I would be very interested as I have bought a set of R7s and waiting spring to put them on.
I am considering adding just front camber plates and DSC controller v3 (if it works already with FAL&GlassRoof for 991.2TTS) , besides that, suspension wise, my car has only Eibach springs and better allignemnt ( like -2 camber all over for now, etc), hope these 3 mods to be kind of enough to keep it simple, but squuze like 80-90% of Hoosiers potential

Thanks, great info! Yes my 335s are the "normal version" not "wide version" and they are more like 318mm wide(contact patch is even narrower), I have somewhere pics showing they arent any wider than 305 TrofeoRs.

So what's everybody doing to their cars this Winter?
For me, nothing settled yet, but may be: Cobb ECU tune and cat delete/bypass or 200 cell cats, 12x21 rear HRE P101's to accept the Cup2 R GT2 RS tires (fronts 9x20 will still work fine), new windshield (this one is pitted pretty bad), touch up the Xpel wrap, and a nice long cleaning and buffing. I'd like to get more downforce, but not really ready to start butchering up GT3 RS or Cup car parts just yet. I still drive this car on the street on pretty evenings.
Let's hear your wish list.

Rear gt2rs cup2r tires R21 are way bigger than TTS r20 even if you run taller tires like 325/30/20, as they are 325/30/21, and awd should throw error messages, brake bias, abs, pasm, etc, maybe you want to take that into consideration. I would be interested myself into such solution if anybody can find a way to make it work.
Using 325/25/21 tires might be a bad idea (even they dont exist yet as far as I know- speaking about Cup2r) as sidewall will be narrow and that might hurt traction and maybe also heat control will be more tricky.

265/335 20 R7 will likely be our best bet for all out, but need trailering or swap at track. They are smaller diameter. With stock springs I'm hoping to make the new wider 335 work when available. We'll see next spring. I had considered RS options also, looks like we've been down the same path.

I'm at a point with my order where I need to finalize my GT silver build. I haven't chosen any body color or gloss black paint options (sills, front grill, ect) thinking the way it comes may be best as far as minimizing cleaning and damage from track rubber marks. Any suggestions on paint options?

I would also consider the HRE R101 Lightweight - lighter than the P101's, same style, same price.
