N/S Bell housing requirement?
 
Is a SFI Bell housing, Clutch and Flywheel required for N/S

If I read the version of the rule book I have correctly (2013 pdf version)….
For N/S or Slower
No roll bar required
Factory Seat belts acceptable.
Drive Shaft loop - required
SFI bell Housing, Clutch, and Flywheel required?

Application is a 1995 Mustang GT Coupe 5 speed .
Should fit into M ,N or O at 215 hp according to ClassRacerInfo
I love that site, by the way!

Thanks,
Brad

Thanks for confirming.

I understand the reasons for good quality components in the clutch department.

I found it a bit odd that factory seat belts were still allowed but SFI bell housings, clutch and flywheel are required.

I’m not sure I understand allowing factory belts and no roll bars if you’re going to require SFI bell housing and clutch parts.

You would be best off with a good roll bar and harness. That's a hold over from years back when a N/S car was no where near as fast as they are now. Plus you might be paired up with an 8 second car in the other lane at some point.

It's an RPM thing. Those "low HP combos" can still wind up pretty high. Especially a clutch car. There are 4 cylinders in SS winding 9K.

And do get a 5 point harness and roll bar. You can't put it in after you get run over by a 150 mph car.
