Proposed changes to SCCA Solo rules for 2013 season
Here's the full document link:
http://scca.cdn.racersites.com/prod/...-july-solo.pdfThe part that is of particular interest to us Yaris pilots: STREET TOURING But then there was this: http://www.solomatters.com/2012/08/a...-seb/#more-730 The Solo Events Board has withdrawn the proposal published in the July Fastrack to put the Toyo Proxes R1R 195/50-15 tire on the exclusion for the Street Touring Category in 2013. The performance of this tire has generated a lot of controversy and kept the internet boards and forums humming. Despite some SEB members concerns about the performance of the tire, the overwhelming majority of member input supported keeping the tire as an option for Street Touring Classes. as a result, we will not put the 195/50-15 Toyo on the exclusion list for 2013.All of this leaves me pretty well confused, but it definitely means that I'm waiting until the 2013 rules are officially published before I sink any cash into new tires. |

You need to catch up a bit. If read the July FasTrack, but then not any subsequent editions you will be lost - at this point you either need to go back and read Aug to current, or wait for the 2013 rules to be published.
The end result is the Toyo is not excluded from the ST category, but it was banned (195/50-15 only) from the supplemental Road Tire category.

OK, so in the December issue they attempted to clear it up:
So my understanding is that if you run HS, you can use R-comps by default, or choose to use "road tires" that are 140+ treadwear (sans the 195/50R15) and run in the RT supplemental class. If you run STF, you have to use 140+ but can use the 195/50R15. If that is the case, then the 195/50R15 seems to be the best choice for those of us who have done enough mods to push out of Stock but aren't ready for Street Mod. Agreed? |

Hmm, my brain seems to be a bit mushy this week. Must be final exams? I seem to be making this much more complicated than it needs to be. Here's my current understanding...
For an H-Stock Yaris you can: 1. Use R-comps without a class change, or 2. Use 140+ treadwear and run RT supplemental (but not the 195/50-15) For me, I have a lightweight crank pulley. That puts me in STF by itself. Aftermarket shocks and springs also put me in STF. ST classes do not allow R-comps, and require minimum 140 treadwear. I have aspirations of further mods (gearbox, flywheel, LSD, etc.) that would put me in some kind of Mod class, but that's probably going to have to wait until after graduation. |
