Ill update when I get more for my next oil change. I'm not 100% sure if they undercharged me or not. Just know it costed me $68 for everything a year ago.
I've been thinking of changing to a carbon one myself because i don't like the chrome. https://speedindustry.com/carbon-fiber-rear-supra-emblem-a90-mkv-supra-gr-2020
I really hope someone make the FT1 style tail lights and maybe add a more visible reverse light. It scary reversing out of city parking spots where cars can't see that you're reversing.
Open vents
Better looking steering wheel where the bottom portion is open
Sequential headlights (noticed the gt500 race car has it)
Custom or re-designed taillights with sequential turn signals
Third F1 style brakelights
Quadtip exhaust somewhat like the GTR
Carbon fiber parts for the piano...
