Hey guys anyone know if the effect of having a front spoiler will have a negative effect on et in the quarter mile drag racing,a friend of mine has 72 mustang set up just like mine and my car is about .25 quicker than his at the same weight and and mph 122.85 or so for him 123.29 for me.Will having that front spoiler change the et or mph or is there something else wrong with his car.

What's the difference in 60' times? The MPH difference isn't enough for .25 et difference. I don't think the spoiler would affect the 60' times.

I am like 1.41 he is 1.45
