- D Street, FoRS - There are only a few national-level FoRS drivers remaining. From what I've seen, drivers switching to DS are picking either a Civic Type R or a Veloster N (Alex Piehl has one of each now, LOL). With the switch in ProSolo to splitting awd (S4) from 2wd (S5), the FoRS is not quite the natural choice it once was due to competing against Teslas & Audis. Still, Civic Type R is not exactly a solid choice for Pro Solo, either, as HS cars have been dominating S5.
- G Street, FoST - At this point, anyone entering GS with a FoST is likely a second owner. Original owners have moved on, except for maybe Brian Anthony, and top drivers are picking the Civic Si if they come to GS. All the Golf GTI owners with potential have moved on, too.
- H Street, FiST - My gut feeling is that the FiST's dominant days are over and the Civic Sport is the car to have now. However, being an economical class, top drivers may be slow to move on.
- Street Touring Ultra, FoRS - Good drivers not searching for a national title seem to keep trying STU with the FoRS. They can be in the hunt at Tours and Pro Solos, but few turn out on top.
- Street Touring Hatchback, FoST, FiST - I feel this is the best option for an upgraded FoST, especially since the leading drivers have mostly left the class and the title will be pretty much open this year. Few people seriously build for the class, however because they think STH is the land of awd, without noticing that class limitations prevent awd from having the best traction. The FiST is just the wrong car here and owners know it, usually only driving here briefly before moving to SMF.
- A Street Prepared, FoRS - I'm unaware of anyone building a FoRS for ASP at the national level. My guess is that since a WRX/STI is competitive, a FoRS would be, too.
- D Street Prepared, FoST, FiST - Bad choice for either in light of PAX indicating SMF, with fewer limitations, is slower than DSP. Cut & flared fenders are a requirement if you're serious.
- Street Modified, FoRS - Cut & flared fenders are a requirement if you're serious. Unlikely to see a FoRS being competitive at the national level, although I don't think anyone has seriously tried. 2021 will be a transition year as the proposed rule change for unlimited engine swaps will need time for car builders to adapt/develop.
- Street Modified Fwd, FoST, FiST - Cut & flared fenders are a requirement if you're serious. Unlikely to see a FoST or FiST being competitive at the national level due to their weight, however I wouldn't totally rule it out if someone is serious. 2021 will be a transition year as the proposed rule change for unlimited engine swaps will need time for car builders to adapt/develop.
- Xtreme Street A, FoRS, FoST, FiST - Not a national class and very similar to Street Modified except on 200 treadwear tires, this is an autox entry point designed for people who modified their cars before they knew about rules. However, if you truly want to dominate XS-A, then know that the SM national champion car can (and has) bolted on 200 treadwear tires to his car and proved unbeatable. On the other hand, the PAX is very, very soft for XS-A, so if you want a leg up in PAX standings instead of running with the SM/SMF PAX because of your mods, this is a good option.
