My Open Letter to the SEB: Move the S197 to STU + Tire Size Bump?
Even as displeased as I am personally with the SCCA rules makers right now, I still regularly send in letters to ask for new parts, rules and classing changes that I see that are ineffective or potentially chasing away competitors to the sport. I can't say much good ever comes of it, but I still send in my suggestions or reply when they ask for "member comment" on a suggested rules change. I've talked about our trials and tribulations in STX class with our 2011 Mustang in this very thread, if you go back to the 2010-2011 posts. We were even racing in STX class in this big boat as late as April 2012. I suspect we probably had the most serious, most tested, most documented STX entry with a 2011-2013 Mustang GT to date?

This 5.0L Mustang was
a total mess in STX class, frankly, and I feel it was mostly down to the maximum 9" wide wheel and 265mm tire that this class requires for 2WD cars (4WD cars are limited to an 8" wheel and 245mm tire). The main problem we noted in this class was that the "maximum tire width" doesn't "scale up" in any ST* class with increasing chassis weight. I feel that the "curb weight per mm of tire width" is a key factor in handling performance, especially on street tires. And especially when you can make well over 400 whp in STX legal trim, like we did. Until January 1st 2012,
we had the option to run this car in either STX or STU, and we did run in STU a bit and the car was MUCH better on wider wheels and tires. But to prevent the Civics from class jumping the lightest ST* car into "faster classes" like STX and STU (which they handily won, quite often), they locked down all eligible cars into a single ST* class.
This was one of the few things I agreed with when it comes to SEB changes lately.
It was about four years too late, but it needed to happen. The unforeseen problem we noted was that this now locked the heavy, powerful Mustang into STX class but most
other heavy V8 RWD cars (above 5.0L) went into STU class, which has unlimited wheel width and a 285mm max tire for 2WD cars. As we saw first hand, this car was much better suited with STU width wheels and tires (if not much more competitive in class), and that maybe it could even do better with a +10 to +30 mm bump over the max STU tire width, due to the much higher curb weight of these and similar RWD solid axle cars already classed in STU.
Anyway - read my "S197 to STU" proposal in
this forum post. If you agree with it and are an SCCA member, please take a moment and write a letter to the SEB/STAC at
this link and ask for these changes. My single voice doesn't carry far at
all with this group, but if more people join in the conversation, we can make positive changes to the various SCCA classes and finally find a home in Street Touring for heavier, RWD cars like the S197 Mustang. Thanks.
Possible Return to SCCA for 2014?
The good news is Vorshlag
plans on coming back to SCCA Solo competition in 2014, if everything gets unscrewed and they don't botch any other major rules. If so, it
could be in a car that looks like this and
hopefully classed in ESP...
As many of you know, there is a new Mustang coming in the 2015 model year (or 2014.5). This car is being "designed for a world market" and will be lighter and
might have a proper Independent Rear Suspension (IRS), maybe from the Australian Ford Falcon chassis. Engine lineup is rumored to include a turbo 4 cylinder, an ecoboost V6 and the 5.0L V8, maybe with direct injection. In order to be a better European export, it is supposed to be "200-300 pounds lighter", which will be a welcome improvement. Very soon we will start seeing more and more renderings and spy shots that look closer to the actual production cars. These could arrive as early as a "2014-1/2" model, to mark the
50th anniversary for the Mustang, so this is going to be interesting.

More 2015 Mustang renderings - no idea how accurate these are.
This upcoming new Mustang is why Vorshlag isn't going to "sit and wait a year" for the SCCA to get their rules fixed for ESP class or the outgoing S197 model, because by this time next year we will have
likely sold our 2011 Mustang GT and will have a new chassis 2015 Mustang on order. Or maybe a 2015 Camaro. Or a 2015 Baracuda. You see,
all three of the Domestic Automakers have
brand new Pony Cars coming in 2014-15, and all of them are rumored to be "smaller, lighter, and IRS". Something might go wrong with one or two of these new designs - delays, extra weight, poor powertrain choices - who knows? But at least
one of these won't suck, and will be all new and lighter - maybe even the already best-of-the-three Mustang? We will get our hands on the "best new pony car" as quickly as we can, then start developing suspension products both in-house with Vorshlag products as well as with our manufacturing partners.
What's Next on our 2011 GT?
We aren't scuttling
both of our S197 cars, as our red 2011 GT will continue to be raced and developed until the next round of Pony Cars arrives, so for at least another year. We have a
gaggle of new parts here, ready to install and test before our March 16-17th NASA Time Trial event at MSR-Cresson. Whiteline sent us updated parts for the rear sway bar, the prototype transmission mount bushings showed up today, and we're working on more endlink options from them.
We made about a dozen of the black T-shirts above, showing a Mustang on the bottom and a Vorshlag logo up top. We can make these to order, next day turn-around, in a variety of sizes. You can find these shirts for sale on our merchandise page located
here. We also picked up two Torsen T-2 differentials for 31-spline Ford 8.8" axles, including a T-2R (4:1 ratio) for the 2011 Mustang, shown above. I can't wait to get that in the car before the next track event! And the winnings from the January NASA TT event arrived - one brand new set of 315/30/18 Hoosier A6 tires. Finally - my first ever track event on a fresh set of A6s! No more old tire excuses for a NASA event (the last two NASA events were run on a sets of tires with over 13 months of autocross and track abuse - excuses, I has 'em!).
There are also several shifter bushings/housings we have accumulated and have now durometer tested (including the squishy soft stock rubber unit) and we will be putting one or more in the 2011 GT before the next track event. And if the Maximum 4-point roll bar arrives in time it will go in as well. There is also a new set of S197 monotubes/springs/Vorshlag plates we've been torture testing on a local guy's 2012 GT for a couple of months that will finally be going on our website to sell, along with several new monotube coilover brands that we will soon be selling.
Let's Wrap This Up
I'm sorry that I had to write such a nasty diatribe about this situation and the SCCA rules making committees, but I feel strongly that they got this clarification wrong, and it directly affects me both as a business owner and as a competitor. And it is one of hundreds in a long line of similar rulings, showing how out of touch some of the rules makers are, in my opinion. Waiting a year for the "rules fix" to trickle down isn't an option for us, as we have other chassis that we need to work with each year and by 2014-ish we will likely be in the new Mustang chassis (or Camaro or Barracuda). Stepping away from SCCA Solo for a year will probably do me a lot of good - by 2014 I will have forgotten how screwed up most of it is.
But it wasn't all venom and poison in this post, as we've put forth a good faith proposal to ask that the S197 be moved from STX to STU, after our two years of dismal results showed it was badly outclassed on the skinny STX tire and wheel widths. We even asked for a bit of extra tire for the big Pony Cars in that class, too. And we are still working with our SCCA region in many ways, including sponsoring the welcome dinner at a ProSolo in our backyard. And while we are selling our 2013 GT and killing the planned ESP project it was purchased for, we still have some tricks in store for our 2011 GT and at least another full year of racing it in NASA TT and with other groups.
