I literally went to a bmw cca autox event for the first time ever in my life in my no line 328i with crappy runflat 17" all seasons and i got 2nd place in the turbo stock class which included n54/55 engines (335i, 135i). You dont need any upgrades, you just take your car there and drive the snot out of it. When you no longer have grip because of your skill set, you get wheels and tires.
the intardnet is 95% troll, 5% actual good shit. so are my posts.
