You’ll spend 10x the time preparing and getting the car to/from the event than you will driving it. Stop now if you’re not committed to that ratio because you’re going to be seriously...

I've been running a DB1 in Solo (CM) for nearly two decades; with the right set up, it's a very capable car. That set up is based on the Hoosier R20 which, in FF sizes, has been somewhat difficult to...

Via R&S:



Time for the class to "put up or shut up" w regards "qualifying" tires :beer::beer::beer:....

Bias Ply...Marked "R20" but are reported as "A7" which I understand is "R60". Specifically:

As I noted in a previous thread, National Solo (Pro/Tour/Nat) CM participation has not recovered post-2020. This has led to a low to non-existent demand for the "qualifying" compound (R25/20) FF/CM...

Just received a note from R&S stating that Hoosier is shipping the FF R20 rears! F Yeah!

As of ~8:15 EST, entry capped at 1300. Wait list now forming. If you're planning attending, I urge you to sign up NOW as there's more than likely going to be at least 5% attrition before the final...

Folks,

Based on Jun/23 SCCA MAC (Modified Advisory Committee) / SEB (Solo Events Board) FastTrack comments, 2025 will be a milepost year for the SCCA Solo CM class; 6"/8"(FC/SR) wheels, Spec Tire,...

Response from Sonya on my inquiry as to where the FF R20 rear order stands:



That is, no change to original production / delivery dates...

All,

Please post FUTURE tire discussion on the thread Jon stated titled "SEB/MAC Asking for C Modified Feedback"

Bringing this thread back to it's original intent, does anyone have any news...

Thanks Jon; long term, a separate thread is the right move...

To that end, my comments from the previous thread:

Thanks Brad; appreciate the efforts to keep the CM/FF tire discussion moving forward! Glad to hear that this is slated for 2025; that is, plenty of time to work through comments, questions, and...

Jim,

First off, I appreciate the amount of effort you have put into locking down both short and longer term supply of the R20 FF rear; it's definitely what we needed to sustain and grow the...

For those not on FB, my feedback on the poll...

I have not had any issue contacting R&S either via phone or eMail...Here's the contact info:

Received confirmation via R&S that the R20 rear tire order is a go!

Thanks to everyone in the CM community for pulling this off. Special thanks to R&S for brokering this order.

Ben/Jim.

Via Sonya from R&S, a summary of payment terms regarding R20 FF rear tires:

Ben,

To clarify, I'm not interested in developing a new set up for 2023; let the rules change process play out and see where we stand going into 2024. That is, we're nearly a quarter into the...

I see the path forward being a rule change to allow FC/FF2000 wheels (ie 6" and 8"). That opens up additional tire brand/compound options. That said, at this point, I'm just not interested in the...

Jim,

Thank you for the posting your submission to the SEB/MAC regarding the FC in CM. I can see your point with regard to aero; although, I think “road racing” wing dimensions could be a...

My role as moderator is restraining my response, but, in short, get bent; any SCCA member can submit a proposal to the SEB. It's on them to decide its merit. I'm done discussing this with you...

Indeed.

Additionally, provide a place for FC which may eventually be converted to FF/CM. Many (National Championship) CM FF are converted FC; Godula (88 Reynard), Ott, and Clements (both 95/96 Van...

To include the GCR spec tire FC to CM, letter #33424 has been submitted to the Solo Events Board (SEB).

In an effort to cleanup and simplify CM rules, letter #33423 has been submitted to the Solo Events Board (SEB).

First of all, congrats to Ben Martinez on his back to back 2021/2022 Solo Nationals CM Championships; it’s first time this has been accomplished since Jim Garry’s 2007/2008 Championships at...

Tom,

Regarding the Solo Nationals T&T, the Sat/Sun/Mon times ALWAYS fill up quickly; higher demand due to those running T/W as well as other folks who are on-site for the whole week.

Rob,

Has your F3 clutch ever failed?

I’ve used the F3 clutch (both Tilton and Quartermaster) in Solo for 25+ years (50 to 100 standing starts per year) and never had one fail. In the last...

Ben,

Given the long term uncertainty of a soft (i.e. R25/R20) FF rear, I like the proposal. From a cost/modification point of view, it seems pretty straightforward. Like you've noted, most (if not...

Ben,

Again, I'm not in favor of moving/mandating a harder tire. I just wanted to point out that IF the R20/25 goes away, Hoosier has other options (i.e. the FF and CF Spec tire). That is, there is...

Brad,

Thanks for the R20 feedback; the consistency of the message is encouraging. I’m just hoping we see the R20 rear soon; my current R25 rears are some of the first of a batch of 60 made in...

Let me clarify my position; as long as Hoosier continues to supply front/rear tires in the R25/R20 compound, I'm NOT currently in favor of a spec tire for CM.

My point is IF/WHEN the production...

I ran into the same issue when I went to purchase tires for Nationals back in mid-Jul; the R25 front was VERY difficult to find. Luckily, I was able to secure what I needed. I knew LATE Aug was time...

Jon,

Appreciate the feedback; it's inline with what I have heard as well. Still planning on talking to Hoosier as I'm really curious as to when they expect the R20 rear to be produced. For my next...

First off, congrats to Ben Martinez on his 2021 Solo Nationals CM Championship; hopefully he shares video of his runs as he was locked in! Also, hats off to the remaining members of the podium John...

Yes, Avon did (does?) make a cantilevered rear for FF Club Racing. I seem to recall it was in 2003-2008 time frame, but not exactly certain. I have no idea on compounds. Give Roger Kraus...
