Default Huge SCCA rule changes for FBody

Is it for real? SFC's are now legal in street prepared? SS and WS6 including 1LE cars now all in FS rather than AS?

Though I don't think my SFCs are legal. I have boxed Hotchkis SFCs and I think they attach to my floorpan in the front. What SFCs out there for our car attach to front frame rails?

Longitudinal (fore-aft) subframe connectors (“SFCs”) are permitted
with the following restrictions:
1. They must only connect previously unconnected boxed frame
rails on unibody vehicles.
2. Each SFC must attach at no more than three points on the
unibody (e.g. front, rear, and one point in between such as a
seat mount brace or rocker box brace).
3. SFCs must be bolted or welded, but welding must be to the
OE subframe stampings, not to the floor pan in between.
4. No cutting of OE subframes or floorpan stampings is permitted.
Drilling is permitted for mounting bolts only.
5. No cross-car/lateral/triangulated connections directly between
the driver’s side and passenger’s side SFCs are permitted.
Connections to OE components such as tunnel braces or
closure panels via bolts are allowed and count as the third
point of attachment. No alteration to the OE components is
permitted.
6. SFCs may not be used to attach other components (including
but not limited to torque arm front mounts or driveshaft
loops) and may serve no other purpose.

Yes. We all wrote letters last year (after I cut mine off). Did you?

Yes. Base level cars only.

Do sub-frames help reduce lap times; I thought they were just extra weight on race cars?

Maybe mine attaches to the front frame rail.... it looks like just a front section of the floorpan to me.

I didn't write any letters to the SCCA

Nope. That's half the reason I cut mine off despite knowing this possible rule change was in the works. Haven't missed 'em a bit.
