I have a story for ya. Kind of long sorry!
I was really considering doing NOS. My uncle is an Mechanical Engineer for the Air Force/master mechanic on the weekend, and I asked him if he would help me do it?
He said why? (Threw me way off!) This is the guy who has done EVERYTHING to his Baracuda. He said, "are you gonna start racing at the track?" I told him probably not.
He said, "if you race at the track I'll do it for you." I said ok. He said, "well I got this catalog that you can order the safety equipment needed to race your viper."
Anyways to make a long story short. He went on to tell me that he had just got back from a lecture where the team that investigated Dale Earnharts crash had given an in-depth analysis of his accident. Then he went onto explain the physics involved in a car/track accident and that if the proper equipment isn't used that it could and probably would end in death or serious injury.
So, NOW I'm looking at safety equipment and contemplating whether I REALLY need to MODIFY my Viper anymore than it already is!
If you track it, Modify smartly. If you're a cruiser/poser(ha!ha!) like me, save you money.
Just my opinion.
