Aaron,

Within official SCCA classes, it sounds like you'd be in Super Street Modified due to the modified cam (which I believe exceeds Street Prepared's allowances.)

We also have a local class called, coincidentally, California Street Modified (CSM). This is a "run what you brung" class on tires that are less than 200 treadwear. If you choose to install 200 or higher treadwear tires, you can run in California Street Touring (CST.)

CSM is, unfortunately, not very popular due to the cost of tires. I don't recall having anyone in the class in 2018, though my memory may be incorrect. CST is one of our most popular classes, and with the improvements in street tire performance I think you may want to consider replacing those A7s with a BFG, Bridgestone or something else on par with them and play there.

Hi Aaron,

Glad to see your giving us a try! Please make sure the passenger front wheel bearing was tightened. :roll:

I concur with Mike that CST is a far more popular class and that csm is a place for Hoosiers. You could get a few other people who are similar in raw time to compete with you since anything goes in csm...

Another wild idea I had that I have only shared with Tom F is, IF we could get a minimum of 5 we could create a BRI class (I think that's what you pca guys have like our Pax). What do you think?

Hi Anthony!

We've talked about this and conical "old school" bearing. Leave my wheel bearing alone... It's fine! ;)

I'm hoping to compete with at least a 3-5 people on some level. Corrected time isn't quite as fun as raw. You've seen the car. Think it would be competitive in CST? It has some V720's I can use, but I'm pretty sure they are nowhere near as competitive as a Rival S 1.5 or the RE-71R.

Well you get 3 drops for a season, so it does give you time to evaluate options. I think either CST may end up being course dependent, and you could just find some guys to run CSM together. You'll have a much better idea in January and yes Re71 in that size will be faster than V720's.

I ran CSM for a couple years with diminishing participation and eventually gave it up for lack of entries and moved to CST. If you want competition, CST is the place to be. Probably all the fast cars are on RE71Rs or BFG Rival S 1.5's.
