This 2009 BMW M3 is very impressive. It’s S65 engine and DCT enables the owner to throw every bit of power without ever slipping. Bimmerpost member Mikewads achieved a record braking 60 – 130 mph in 6.23 seconds, completed in 904ft. on a -1.7 decline! Here’s how he did it:

I went back to the shop, warmed the nitrous bottle to 900psi, and installed the 100 shot nitrous/fuel jets. I was unable to engage the nitrous in 2nd gear because it would just blow the tires, so I waited until I shifted into 3rd gear (you can actually hear the switch in the below video). 33F / full weight / 93 octane.
