Until the PRO86 ruleset is reflected in the Conference rulebook, I am making a post here and attaching the PDF so folks can readily find it who are building to the class.

It's nice to have a primary physician, but when I didn't - this process sucked. When I didn't have a primary physician - it was a nightmare to find a place that do this type of physical - I went to 5 and none of them I wanted to be in. I had waited too long to renew and getting an appt with a...

Maybe NWMS and Sovren can retain their combined event and relocate it to ORP? Early June would be a lovely time to be at ORP.

The license form says "License fees can only be paid through MotorsportsReg.com" However, I cannot find that on MSR. The one I did find ended on Dec 31 2020. When should license applicants expect a new listing on MSR so we can make payment toward our 2021 license? Thank you in advance.

I'm looking forward to this upcoming event and have heard that it is a "definite go". I hope the number of entries grows as this is only IRDC race this year. The Cascade race was enjoyable and after attending a few races this year between ICSCC and SCCA, I've found that adhering to the safety...

The Conference 2019 competition rules are not yet published but the CT4 class reads: A. Purpose - The CT4 class is intended to provide competition for commonly available, recently produced cars in a near street legal form and allow cars prepped to popular classes within Conference that run...

The SCCA class, Touring 4, is showing positive growth and has a very attractive rule-set for new additions to racing. The cars are modern, the prep limited and the operating costs low; which is all part of the attractiveness. We thought about adding T4 to Group 5 to attract these SCCA folks...

I'm wondering if anyone feels like safety and/or driver skill has taken back seat lately? Is Battle Royale a new feature at Conference events? Group 5 and 2 are budget/entry level run groups but they now feel more like groups for people with disposable cars. It seems like a culture of...

Maybe I missed all the goodness since I don't have the book of faces but I'm looking for info on Spokane. What improvements have taken place? What is this 'short track' race mentioned on the schedule? There's a short track? Thanks.

Hola everyone, IRDC has a (4) session HPDE on Friday May 18th with the TnT. $180 entry. It's not listed on the main page on MSR so it needs some help being promoted. If you have the book of faces or are a member of a car forum - please promote. Registration is bundled in with the...

Just sayin' Spokane is a moral imperative! Great track, great club, great food and a triple race weekend. The weather is supposed to be downright perfect - mid 70's to mid 80's. It's not too late to register. See you at the track.
