Ive built plenty of M cars but honestly the G80 market is such a mess right now. Everything feels like cheap carbon fluff and I actually need performance since Im hitting heat soak issues at the track here in Phoenix.

$4500 budget

streetable suspension

real cooling gains

What are the actually functional parts that dont just look pretty but actually shave time?
