Our latest update to our massive S197 Mustang Build and Development Forum Thread (hosted on 5 forums) covers 4 separate events and discusses a variety of subjects.

First we cover a NASA race in late April where our TT3 prepped 2011 Mustang GT crushed its old track record from 2013 by over 3 seconds while winning the class by 6 seconds. We talk about the changes that we made over the past 12 months to justify this amount of lap time drop on a car with zero power improvements and actually more weight added (tires, wing, shocks, front aero).

We discussed our custom order of a 2015 “S550” chassis Mustang, which is all new. And after going to a car show we got to measure a few things on and sit inside one of the pre-production cars. The 8 minute video of inside, outside and underneath this S550 car got some hits. Again, click here to read the 3-part build thread update for lots more details, pictures and in-car videos. Thanks!

The 3 day Ultimate Street Car Association’s “Optima Street Car” qualifier event in March here at Texas Motor Speedway was pretty epic. Vorshlag was in attendance and we have split our normal event write-up into three sections. The post that went live today covers Saturday’s Autocross and Speed Stop competitions. There’s also a listing of some used parts listed in our clearance page that came from our Mustang, as well as a discussion about Pro Touring and how SCCA’s CAM class relates to that.

We entered our NASA TT3 prepped, fully street legal 2011 Mustang and did fairly well in the Autocross (2nd) and Speed Stop (3rd) competitions on the Saturday of this 3 day event. We also placed 4th in the Design and Engineering challenge, which was a judged event. You can read more about how we did on Day 2 starting at this forum post.

Vorshlag and 7 of our testers and customers went to a Optima Ultimate Street Car qualifier event at Texas Motor Speedway the weekend of March 21-23rd. We did very well in our familiar red 2011 Mustang, which we run in NASA Time Trial, SCCA autocross, and other events. We write about this new “USCA” series of qualifier events, which are a series of 3 day competitions for streetable cars on 200+ treadwear tires.

Entrants have to compete in five different events, which we explain in this series of posts to the S197 Mustang build thread. This is the first of 3 sets of posts about this event, so stay tuned for more updates and links to the next two parts. Thanks!

We had a good couple of events this month and racked up two wins at NASA in TT3 and another win at Goodguys as well as many other subjects in the lastest S197 Build Thread (5-parter) Post.

The new 345mm Hoosiers were a big improvement to the 3802 pound (with driver and ballast) TT3 prepped Mustang GT on the Motorsport Ranch 1.7 mile course and we lopped nearly a second and a half off of our previous best lap times there. The red car won the class both days and set a new TT3 track record of 1:17.310. We talk about brake temps, tire pressures, wheel spacers, and all of the other settings and changes we made for this weekend.

Terry writes a lengthy discussion of our trials and tribulations relating to the factory ABS/Traction Control unit on the 2011 Mustang, as well as a new solution we are testing (shown above). Lots of tech to dig into on this discussion.

The white stripes, decals and overall “livery” on our car for the past two years was scrapped in March and we ran a couple of events “in the nude”, letting the red paint and beautiful flares/bodywork by Heritage Collision shine through. This was done in preparation for Goodguys and USCA “street car” events, as well as a new set of BFG Rival tires in 315mm front and 335mm rear sizes. and believe it or not, our test mule Mustang really is a street car.

The car looked mean in all red and we took the car to the Goodguys All American Sunday autocross in March.

When it came down to the Goodguys event we put in some good laps and won about about 2 seconds. Video from this event at NASA @ MSR are in the mega-sized 5-part post, posted today, linked here.
