SO, what do the powers at be think about running the MX-5 in the narrow class? I am down for running a Miata class, I've never run the -1W rears in a race setup! It's quick on the narrows, and only traction rolls when I get hamfisted on the radio, so it should be even better on wide rears! I wanted an RX7 anyway, so either way is good with me!!!
Thanks Guys and Drive Fast!!! Drew

Sorry guys! I missed these earlier and there has also been a similar discussion in the Facebook group. Here is what I think:
The Narrow class rules do say the body must be one "
that originally ran on 8.5mm Narrow wheels all around and running a narrow front end" but I think running the MX-5 in the Narrow class should be allowed even though it originally comes with wide rear wheels, as long as we comply with the rest of the rules that say "you MUST run zero offsets 8.5mm all around". I'm also OK with the Dodge Viper being run in the Narrow class too. My MX-5 is currently set up on 20mm N0/W0 and handles exceptionally well in near box stock trim. I have not tried it with N0 all around, so I don't know if that will significantly change the handling.
As far as a separate MX-5 class, if we have enough racers with MX-5 times we can have a separate class. Another idea is to expand the Porsche Cup Class rules to include the MX-5 body. That class doesn't limit the rear wheel choice to N0, and the MX-5 will probably have to be RM anyway because it would be hard to fit any other motor mount under the body because of the trunk. One benefit of this option is that folks that can't find a Porsche or can't spend a fortune to get one can run an MX-5 instead (like in real racing 
).
My suggestion is go ahead and get the MX-5 and start running it. We can test it informally this month to see if it better fits into an existing class like Narrow or Porsche Cup, or would be better off breaking it out. You can run it under both sets of rules (i.e. N0 all around or W rears) and compare your own times to see if its better one way or the other. Once we have more information about how they perform compared to other classes and see how many MX-5s we have we can decide where to slot them in the Challenge.
Drive fast!
