And I quote: " what's up guys, one of my tires is a little low on pressure is it ok to add air to it while it's warm or do I need to wait until it cools down? I don't want to mess any thing up so I just thought I'd ask all of you experts." COME ON!! YOU GUYS GOTTA ADMIT THAT SOME OF THE QUESTIONS ON THIS POST ARE ABSURD. Get some balls, live on the wild side put the damn E36 M3 oil cap on an E30 if it doesn't leak. What the hell while your'e at it get really crazy and change your own oil! To all of the guys who have taken the time to learn as much as possible about the E30 M3, you have gotta admit that some of the questions have been pretty childish lately.
