'21 GT4 - Must have upgrades and accessories?
Is there a definitive guide / thread out there for must have upgrades or accessories for the GT4? Just have my V1gen2 radar detector installed with a blend mount and hard wired, but that's about it so far.
Any links to awesome products and must haves would be appreciated.

I think clear side markers are a must. Other than that, get out and drive it as often as possible.

If you find the way it handles potholes too harsh or abrasive, or are looking to shave a few tenths off lap times, DSC Controller

My "must" haves so far:
- T-Design9 memory module
- DSC controller given my love of this on previous cars...leap of faith here really
- Clear side marker lights
- Euro style alcantara visors without the warning labels
- CF key fob cover
- Black/silver hood crest to go with my white/black two-tone car
- Integrated radar/laser, likely Radenso RC M plus ALP
- Antigravity lightweight battery pulled from my last car

Honestly, I'm not sure about best...I didn't do a ton of research. These came recommended and from what I can tell having ordered them, they are high quality -

I would also add:
- matching ext color key "cheeks" (in my case Miami Blue)
- GMG air diffuser: https://shop.gmgracing.com/collectio...w-air-diffuser
- Ed's LWBS seat bolster covers (if you have LWBS)
- BMC Air filters
- OPF pipe bypass (Akra, Soul, Cargraphics, Dundon, Fabspeed etc)

100% on the DSC controller. This thing is magic. Getting the rear toe links and then alignment. The car will be totally locked in then for my needs (mostly street/canyon runs) and way better than stock set up.

conversely, I am not seeing *any* incremental value in the DSC vs. OEM PASM as of now... maybe I will feel differently when I get the toe links and alignment.

I don't have the car yet but I already purchased; Clear Side Markers, SOUL OPF Delete Pipes, TDesign Module, Wind Deflectors for the windows, Porsche Front Cargo Liner and Rennline Aluminum Mat. I will be adding the LWB seat bolsters as well.

If you're only doing one or two track days a year (if ever), then it's not worth it. However, the price for 19" tires is generally lower than 20" tires, and you generally have a larger selection of 19" tires to choose from, so if you're doing several+ track days a year, the savings add up and 19" (or 18", for the turbo models and cars running the PFC brakes) end up saving you money.
