If that spoiler isn't your thing, maybe the big carbon fiber APR wing we used from 2012-2014 suits you better? Like the spoiler above, this also only mounts to the trunk so you don't have to cut into your fenders or anything else to add this. If you pick up a spare trunk, like we did (for $150), you can mount this wing to the spare and "swap trunks" between track days and street use.
We acquired a brand new Magnaflow X-pipe for 2011-14 Mustangs that we're selling discounted by $100. It wasn't used on a customer's install and had been sitting on a shelf for months. It is brand new.
This was one of the many Upper Control Arm and UCA mounts we tested in our car. This configuration is an unmodified UPR brand bolt-in upper mount with a Spohn Performance adjustable UCA with a Del-Sphere upper joint, also known as a Johnny Joint. Vorshlag customized the upper mounting bolt (larger) and made custom mis-alignment spacers. It works better than Spohn ever intended, but it makes a little noise, like many aftermarket UCAs do.
Spohn Performance adjustable Panhard Rod, M5-105, built with 4130 chromemoly steel tubing and Del-Sphere ends. This unit worked fine and we used it until we upgraded to the Whiteline Watts Link kit.
Mustang 18x11" Wheel Fitment Video + New Sizes
When we bought this 2011 GT and started racing it immediately, in mid 2010, I was shocked at the utter lack of wide wheels that were offered to fit the S197. I mean it had been out since the 2005 model, but most folsk were still jacking around with 8 and 9" wide wheels, or worse, using 18x10 or 10.5" wheels that POKED out the fenders like mad. I bought a variety of wheels (1 of each) to test 18x9, 18x9.5", 18x10 and 18x10.5" sized on the front and back of our test mule, trying to fit as much as possible under stock fenders.
After coming up empty handed we finally decided to pull the trigger and had our own 18x10" wheels made, which we calculated and verified would fit easily under stock fenders both front and rear. This D-Force 18x10 ET43 wheel was a success and now lots of other wheel makers have this exact same size. But I knew that we could fit more, so we did some more calcs and ordered 18x11" front and 18x12" rears, and made some suspension tweaks to make them fit with a 315 at both ends. We ran on this set-up for much of 2012-2013 before finally deciding to flare the fronts then the rears to fit 18x12s and even wider tires (335F/345R). the car only gets faster every time we up the tire and wheel width.

During 2013 we decided to try an 18x11" wheel for both ends, and came up with our proprietary fitment that uses radically different offsets on each end of the car. We have sold lots of 18x11" wheels now and have all the tricks and tips and this video above explains where the clearance is closest and the best way to have maximum room for street an track use. Jason and I made this video in about 10 minutes, so its not exactly Oscar worthy, but it gets the info across. We also touch on tire sizes to use on 10 and 11" wheels.
- 17×8.5 offsets from +6 to +50
- 17×9.0 offsets from +12 to +58
- 17×9.5 offsets from +19 to +65
- 17×10 offsets from +25 to +72
In addition to the many 18" sizes we've run on various cars, Forgestar has launched an F14 wheel in
several new 17" sizes. We begged them to do this for racers that were asking for their style of "custom built" flow formed wheel process and these are finally coming on line. There is also another F14 size we've been asking them to make that is about to drop - an even wider
18x13" size. Look for this big 13" wide wheel on our 2011 Mustang soon, and we've got sets being built for C6 Z06 customers as well. Bigger really
is better in this instance.
Global Time Attack at Road Atlanta - May 9, 2014
The two weeks after TWS and before our trip to Road Atlanta were extremely hectic at the Vorshlag shop. We had customer cars with insane deadlines and our guys were working extra hours to get caught up. That meant our pre-race prep on the Mustang was very very delayed.
Since we were leaving on Thursday at 3 am, the car was quickly prepped and loaded in the trailer on Wednesday. The guys pushed some fresh Motul RBF600 fluid through each corner to make sure it was bled and clean, the same set of 335F/345R Hoosier A6 tires from TWS were left in place, 8 fresh quarts of Mobil1 15W50 synthetic oil and a Wix filter were swapped, and the car was given a good pre-race tech inspection. Shop Manager Brad noted the XP20 Carbotech front brake pad depth was only 1/2 thickness, and asked me where the spare pads were.... err... good question. "I think they are in the trailer". I went to get the trailer, no spare pads. Crap. This
WAS the spare set of pads. "No worries, we'll manage", I said. We have 3" front brake ducting, so the pad won't get that hot. Ha.
Note: getting in a rush does not excuse the mistakes I made in this pre-race prep. We tend to push our own car to the back of the line when it comes to shop time, behind paying customers. My not taking the braking system needs and consumables seriously enough led to the accident below. Our Motul rep was
shocked that we were still using RBF600 fluid on this somewhat fast and heavy Mustang. "You should ONLY use
RBF660 on that car!"
Motul RBF600 is great brake fluid, and appropriate for 90% of our road course customers, but the boiling point is a touch lower than their 660 fluid. We've been pushing the limits of brake system sanity in this 3800 pound car and I knew that our measured caliper temps were nearing the boiling point of RBF600. Don't ignore advice from your suppliers and don't ignore the data you are taking.
Learn from my mistakes.
This Road Atlanta GTA event was the only "close" event on their 2014 schedule, and its at the same track as NASA Nationals East this year. It made sense early in the season to add this GTA @ Road Atlanta event to our own 2014 race schedule. Having never even been to Road Atlanta, much less driven it, we knew that I needed to get some track time there before going to NASA Nationals. This road course is notoriously tricky, and ATL locals tend to have a massive advantage over newbies at this track.
