great advice, let me tell you - I was already lowered and took the stang down the road up to 130mph - I stopped there because the car felt unstable. The only mod after that I did was a Mach1 chin spoiler... I took the car up to 140 and let off (just because I wanna live and I was on a public road and was going to fast as it is).... anyways at 140 with the chin spoiler the car was MORE solid than without it at 100mph. Its unreal how much that little piece of plastic helped. I doubt it was giving me any real downforce, but it did keep the air from getting up under the car and lifting it.

 

It's certainly going to help keep your front end planted, it's not going to help your rear end's downforce much at all like you said. I was surprised nobody mentioned lowering the car and putting on a chin spoiler...

 

I took 'lowering' as a given.

 

the stock block can't handle over 500 hp stock. Is that motor beefed up?

 

WHAT?!?!

A stock cast iron block has proved to hold 830 hp.

 

It's not a 4.6 BTW and I'm sure the motor he built was made to handle the horsepower..
