wheel to wheel without a cage and full safety equipment just won't happen.. that scares me just thinking about it.
I've raced LeMons for several years and many current and ex-SCCA racers are playing there. Lots of the front-running Club Racers also build, race, and maintain theirs and others' Chump/LeMons cars. Our KeMons team plans to do start doing some Chump races this year as well, and will probably move away from LeMons due to the stupid penalties and down time of simply going 2 wheels off.
....A note on driver skill here... At Lemons, if you spin the car, hit someone (minor contact), or put 4 wheels off, they park your car for half an hour. If you do it again, they park you for an hour. Do it a third time, and your day is done. If you HIT someone, you get more severe penalties. bad driving is very harshly penalized. I haven't run ChumpCar yet, but I understand the rules are closer to club racing. i.e. 4wheels off and continue is no big deal, but punting someone is dealt with quickly and severely.
the cage in our LeMons Miata is an SCCA-legal cage-- had it done by the same shop that did the cage in my STU car. LeMons cage rules are pretty much the same as IT cage rules, except they still allow ERW tubing. I *think* that rule has been changed, with previously registered cars grandfathered in. Just like older IT cars.
the required driver safety gear is the same as SCCA. Must be SA2005 or better helmet, full face, SFI 3.5A/5 or better suit, some sort of neck protection- at minimum you need a collar, but many/most run a HANS or similar. If you have an open top car, you must wear arm restraints.
You gotta have a fire extinguisher. handheld is OK, but many teams are running a full-blown fire bottle and fuel cell.
the prep level on the faster-running LeMons cars are similar to an IT-type build. big radiator, blueprinted engine (some with intake, headers, and cams), coilovers, better brakes than most IT cars since brakes are considered a safety feature and don't fall under the $500 rule. I see Wilwoods and bigger OEM brake setups on many cars.
As for the safety differences between the cars, as long as the car meets SCCA's safety requirements, I don't see any reason why they shouldn't be allowed to run. no windshield? Treat it like an open top Prod or GT car, and require the driver to wear full face helmet and arm restraints.
I see this as a good entry level class to get some of the serious chump guys entered into
Licensing? If the car is safety-legal, then the drivers can go to an SCCA school and get a novice permit. Houston Region's Super School is a 2.5day event (fri evening classroom + sat & sun on track) and was about $600 IIRC. I walked away with 8 hrs of wheel to wheel track time and a novice permit. done. That's the same cost of running a Chump race for most of these people with just as much track time, so they won't complain.
Hell, I almost want to go back to another school just for some additional instruction and cheap track time.
..back to the point..
I don't see any reason to call this a bad idea. done right, it will bring new people (of all ages) to SCCA, and expose some of the old stuffy club racers to people who like racing because it's FUN.
