Cars: Nissan '71 Skyline Race front wing + window tint bug

This is really bothering me as I saved up to turn the 71’ Skyline GTR 2000 into a track car:

When you upgrade to a race front wing… it doesn’t show up during races/replays… WTH??? Guys, I understand you were on a major deadline… but seriously, did the game even go through quality testing before release?

I’m really trying hard to hold it in now, but we’ve stuck with you for 10 years now… COME ON. Please ‘test drive’ your game for bugs and iron them out!

Also when you tint your car, the inside of the windscreens are completely transparent… as in 100% see-through. Don’t tints keep the sun out? Why are the windows completely transparent when viewed from the inside? Funny thing is they’ll show up as tinted in the cockpit view. face palm

Same bug is in Horizon 2.

Anyone, please? We need to bring these things out in the open, or they’re never getting resolved.
