In other words your mph will show how fast your car is. 100mph is good for 14.0's on a fwd car while and a little faster on rwd ..simply because of a better 60ft maybe 13.7ish. Also if anything spinning increases mph to inflate numbers hence why alot of people trap lower on slicks. Of course there are ALOT of other variables that go into the mix also. So take this comment with a grain of salt lol.
