The MS class allows a 130" wheelbase and forward streamlining (ahead of and including the cowl).
I am thinking what I would like to do is stretch the wheelbase to 130" and move the 2 front tires closer (they are about 4' now and was thinking somewhere about 1.5-2').
I was wondering:
A-is this legal in my class to move the tires closer together
B-would moving the front tires closer adversely affect handling
C-will doing this much BS be worth the time and effort (the reasoning behind wanting to move the front wheels closer is because I can go crazy with streamlining the front end.....a benefit for me because the car is a mid engine and don't have to worry about engine fitment in the front).
Good idea.....bad idea?

Sounds like the rules are very similar to comp coupe. If so then I would think you could change the front track width and I would do it. There is no need to drastically narrow the front as the air will still see the car at it's widest point, but narrowing it some sure couldn't hurt and would give you the option of better directing the air that does go towards the body as you have talked about.
You could then also work on the front wheel openings and try to avoid them acting like parachutes. If you can totally cover them then the narrower track would be worth it right there. If not again look at the deflectors that Blowfish uses at the front of their wheel-well openings that deflect the air just enough that it reattaches right behind the wheel opening. Of course they used a wind tunnel to find the perfect solution. If you don't have a wind tunnel you might try Hooley's Okie wind tunnel. We use an air hose pointed at the part of the car in question and sprinkle baby powder into the air stream and see where it goes
.
The longer wheelbase should help with the handling and would help to move the CP rearwards (good). Now once the car is in a spin, hopefully you will avoid this, then the the long/narrow wheelbase might be a negative. I would really work on the CP/CG thing and get it right and get the weight in the car you need so that a spin is less likely to happen as a result of tire spin on the top end.
Is it worth it. Depends on much you want to hand that 250 mph time slip to Dan
