Sorry for the double post, but I feel this is a separate matter that deserves its own post.
So I was driving my (almost) stock FD round Eiger, when suddenly...
...I noticed that my brakes (?) are on fire?!
I wasn't even on the brakes at that moment!
Upon closer inspection, it's not my brakes, but the internals of my wheels giving off that odd orange glow that brakes in the game are known to glow in. Not the FD's, though, since it's way too light (and slow) to really make its brakes glow without tuning.
I tried replicating this glitch in a brand new FD in Vintage Red, and the same thing happened.
Apparently, it's a glitch that affects specifically the stock wheels of the ɛ̃fini RX-7 Type R '91 (the premium one). I tried replacing the stock wheels and driving under the same conditions with the Mazda RX-7 Type R (J) '91, and I couldn't replicate this glow.
Some technicalities:
I had ~203km on that Competition Yellow Mica FD at the time of the glitch. The Vintage Red one had 0.
Both FDs were entirely stock aside from being fitted with a Fully Customisable Suspension, with settings identical to stock (except without the stupid 0.6 rear toe angle).
Track conditions were 0 weather, 0 water, real grip loss.
