Question cf hood?

Someone tell me why a cf hood bumps you up in class (ex. DSP to SM)?? I was thinking about gettin a cf hood until I read the SCCA rule book. Is it just cuz of the weight reduction?? Even an oem cf hood bumps you up

I don't know anything about SP. But I heard it bumps you out of STS because of a safety type thing. Something about CF hoods not being crash tested. Similar to how you can't replace an airbag steering wheel in STS either. When I say "safety" I don't mean that's it's unsafe, just that it doesn't fit in the "spirit of the rules".

I think SP was originally meant to be more of a street legal class hence the name "street prepared", and it slowly turned into the bastard it is today. I believe they call this phenomenon "rules creep".

damn these rules I looked in the "SP" section of the 2006 Solo rule book, and basically I can not replace the hood.

it also lowers your center of gravity and brings your 50/50 closer to perfect, especially for FF

Solution 1: Take your stock hood and grind the underside of it until it is half the OEM thickness.

Solution 2: Stop bothering.

You think that's bad? I put a larger hood scoop on my car and it bumps me to Street Mod. Well, not like I'm not supposed to be in SM anyways, but that was back when I still had a high-flow cat on my car.

Do you actively compete with the car? Or do you just do it for fun?

My approach is to build a car the way I like and to hell with the rules. If I end up in some tube frame 600hp class because I have a triangulated strut tower bar so be it because all I want to do is have some fun and improve my skill. If I wanted to be competitive in any form of motorsport I'd purpose build a car for it. But then again I've only done one event so my opinion doesn't count for much.

Actually, it does:

"Modified cars are production-based cars with any of the following modifications:
  • Any internal engine modification (crank, cams, rods, pistons)
  • Any external engine modification that alters fuel delivery (alternate carb, altered fuel injection, fuel-air ratio adjusters)
  • Any non-factory engine replacement
  • Welded chassis reinforcement, including welded roll bars/cages
  • Alternate or altered springs
  • Altered suspension geometry (relocated pickup points, alternate suspension parts to increase factory alignment adjustment range such as camber kits, camber plates, or slotted strut mounts)
  • Alternate main body panels (doors, hood, trunk lid, fenders, roof panel, windows)
  • Removal of factory interior parts (seats, interior panels)"
A CF hood (or other lightweight body panels) is usually a pretty significant weight reduction, and a group of lightweight panels done right can shift the CG location by a considerable margin.
