How fast stock 370Z really is and how will BERK and K&N's affect on that!

If you are spinning you are obviously losing time so before you throw in the towel try noting down your parameters first. Also, you are better off going to a track which will hopefully have some rubber laid down and have some temp as well. Cooler temps mean harder rubber which means that you will spin. Of course, if you are doing this on street tires which are made for longer wear hence, harder compounds you will end up spinning and again...your times will not be very good.

Put some drag radials, warm them up, note the track, time, temp, humidity, and post up some times before/after your mods.

Good luck!
