KTML. You do realize that is today's sportsman, stock and probably other class names. They usually race pretty good, they build there own motors and run a 9" rear. Short, usually 3 or 4" spoilers across the back. A plastic nose that actually resembles a Monte Carlo or Camaro.
i can never reply with quotes on here..... MasterSbilt_Racer to reply to you comment about the spoiler, i'm sure getting rid of spoilers would help but that's not the only thing providing downforce when cars are hiked up like they are. the whole car is turned into a giant spoiler, from the tip of the nose all the way to the end of the deck. that's why "hike" is such a problem. would removing the spoilers help? i'm sure it would but can you imagine how stupid these cars would look with no spoiler? they already look like they were built by a cross-eyed drunk the way the bodies are skewed and bent.
The spoiler is the biggest piece of the rear downforce. They would look fine with no spoilers. You could leave the spoiler sides, if that makes you feel better. You remove the spoiler and go back to curved roofs, it's a whole new world. Even though the nose is problem #1. Modified have no droop rule and they have nowhere near the aero issue.
I have some pretty unique experience and perspective on this as I've updated antique stuff to be competitive. I've seen what's aero and what's suspension due to accidental experimentation. There's not many people who have run modern geometry under 08 bodies. Not many people who have intentionally raced with no spoilers.
You said you wanted to limit what big money could do? Big engines are big money. Hundreds of pounds of reduced rear downforce really caps how much power you need.
Racers outsmart silly rules we keep piling on. Tech men don't dq people. That's why we are where we are. Only physics can save us.
your right about limiting the big expensive engines , back in early 2000,s a big engine was only useful down here till late may or early june , after that when the track went slick , a 1/3 the cost spec engine could win races , all these modern improvements have allowed the use of the 900hp engine all season .
