SCCA catagory for my 914-4, racing catagory 914 Options

[FastFroggy]

Hello all,

I previously ran HPDE events and autocrosses prior to my engine issue. I am now wrapping up my 914-4 rebuild and just passed my SCCA Licensing Class. Really enjoy running the car. Would like to see if there is an SCCA class I can fit it, but looks tough. Looking for guidance on the best path forward given my stated priorities:

1. SCCA regional level minimum
2. Extent of further modification needed
3. Relative competitiveness in class

My car:
a. 1973 914-4 with up to date safety items(Cage, extinguisher, seats, harness, etc)
b. 2.0l stock internals
c. race headers
d. large bore twin carbs
e. 5 lug conversion
f. 911 1973 rotors
g. 911s calipers front
h. fiberglass fender flares

Please PM me with feedback. Thanks, GregM

Yes, I have my school signed off.

Plan is to have fun, race hard, be competitive. Target is to finish engine install and track ready by end of May. Make vintage event at WaterfordHills in late August. Investigating to run SCCA road race series.

Utah SCCA: I already contacted them a few years ago with no real feedback.

Yes GCR, which refers to PCR for Production Competitions Rules(i guess)

I need to check the front rotor specs, but at least the rears on a 914-6 were solids i believe. I run vented 911 rear rotors(aka 916 rear). Would it just be a 2% weight penalty or NOK?. Same question for front "S" caliper?
