Supersport Mk2 Race Report From Mid Ohio!

On the July 4th weekend the Supersport Mk2 made it’s North American racing debut at Mid Ohio Sports Car Course racing with NARRA in the GT1 class.  The competition in GT1 was all Dodge Viper Comp Coupes running V10 engines.

I was again surprised how much the performance bar is raised when you are racing a sanctioned event as opposed to testing at our home track.  I was also a bit surprised by the higher than expected level of competition from the very well driven and professionally prepared cars at NARRA.

Friday was a test day.  We started off running very old tires just to get a feel for the track and the car.  Craig Stanton, our pro driver, did a fantastic job  of getting up to speed quickly.  The second session was skipped to give the crew time to work on the other car we were supporting at the event.  One thing about NARRA, they give you lots and lots of track time for your buck!

For Friday’s third session we mounted new Hoosier tires.  Craig started pushing hard, running fast times but reported the handling was going away.  We returned to the trailer and started inspecting the car.  Another big surprise! The rear lower control arms are bent.  This is the first time we have run the car with improved aero for more downforce and stiffer rear springs.  The control arms were simply not able to handle the increased loads.  We decided to repair and reinforce the control arms, using the trailer landing gear as a press and straightened the arms. Craig went to Home Depot to acquire material to reinforce and strengthen the arms. A late night of cutting and grinding had everything ready for welding in the morning.  The repair and strengthening was rather agricultural but certainly appeared capable of doing the job.

We skipped Saturday’s warmup session and were ready for the qualifying session.  Craig was being very conservative, not being too sure of the control arm repairs and qualified 4th in class.  Inspecting after qualifying showed that indeed the repairs were all holding up just fine. Now we started setting the car up for the race.  Saturday’s race showed us right away that having the lowest horsepower but best handling car on the track was a challenge, especially with Craig’s instructions to “take it easy, we really want to run Sunday!”. Craig was held up by the cars ahead in the curvy bits but when he got to the straights the Viper’s top speed allowed them to pass. Without diving hard in the corners Craig could not negate their top speed advantage.  The half hour race was the longest we have run the Supersport Mk2 in anger.  Craig’s smooth consistent driving earned the car it’s first podium appearance!

Sunday dawned with new enthusiasm from both driver and crew.  Today we would push harder!  Spring changes, aero changes, shock changes, alignment changes, all were made.  After the morning warmup session Craig’s immediate response was “better,better,better!”.  For qualifying a new set of tires yielded Craig a quick time right out of the box.  We are fastest in our class so far so we sit in pit lane and watch the competition.  Craig says he has more left in the car.  On the last qualifying lap Saturday’s GT1 winner just nips us for the pole.  Craig says “No problem, I have plenty left”. He will get them on the start and push hard enough to gain enough in the corners to be able to maintain his position and move up.

On the race start Craig does a fantastic job easily passing the GT1 pole sitter on the outside and starts after a GTU car just ahead.  The GTU car is leaking lots of fluid and Craig cannot run too close without risking the car.  He is pulling away leading the GT1  class when the handling goes away.  He pits and the crew finds that the rear sway bar link is disconnected so we decide to retire.

We learned so much over the weekend.  First, we learned that Craig loves the car.  His common refrain after getting out of the car was “You have a really neat thing here” and “I just love driving this car!” Secondly, we are really close. We need to design and manufacture new rear control arms, thoroughly test them, and retrofit the existing cars free of charge.  Thirdly, racing will push us to refine our setups.  The car is very responsive to changes so optimizing it is achievable and easy to do and changes don’t kill the crew.

The engine, transmission, and electronics performed flawlessly and are proving to be state of the art and very reliable. This complete car is truly a drivers car.

As we work towards building our one-make series for the car we are enthusiastic and very confident that the Supersport Mk2 Spec Series will prove to be the best GT series for drivers on the planet.

North American Racing Debut!

Announcing the North American racing debut of the Supersport Mk2 at the NARRA US GT Championship GT1 race at the Mid Ohio Sports Car Course July 3-5, 2015!

The 2 liter GM Ecotech GDI turbo will be up against some pretty stiff competition in the GT1 class, which is mostly V10 powered Dodge Vipers.  Fortunately the Mid Ohio track favors handling over horsepower which will help us!

Craig Stanton, one of North America’s top pro drivers will pilot the Supersport Mk2 around the fast and technical track.  This should be really fun to watch!

We would like all interested people to join us at Mid Ohio. Please note that this is not a spectator event so email Jackson Stewart and he will arrange a VIP Pass at the gate. Email [email protected].

Having Fun at Hallett Motor Speedway!

Supersport owner Cal Kalishek took his Supersport out for a run on his home track, Hallett Motor Speedway in Jennings, Oklahoma. He reported “First track day with chassis #008. Can easily run with V8 powered street cars. Still more potential in chassis, suspension, and engine. Need to sharpen my skills to take advantage of all 999 Supersport has to offer. >8O”.

We are excited to see owners beginning to really experience and enjoy the Supersport. Cal has been invited to run with the Comma Series in wheel to wheel racing at his next outing but has decided to run a couple more High Speed Touring days before stepping up. His next outing will be in mid June with the Midwest Ford Shelby Club.

The Supersport and the NA Car of the Year Cadillac ATS


The Supersport Shares it’s Heart with the 2013 North American Car of the Year Cadillac ATS!

Both the Supersport and the Cadillac ATS use variants of the highly refined General Motors Ecotec series of engines.

Cad 1

The Supersport’s 2.0L direct injected turbo engine with a bore and stroke of 86 mm, dubbed the LNF, is tuned to make 345 hp and 330 lb.-ft. torque.  The Ecotec in the Cadillac ATS sharing the same specifications, dubbed the LT6, is tuned for street use at 272 hp and 260 lb.-ft. torque.

Cad 2

The Ecotec engine family is a highly refined group of engines used world wide in a variety of vehicles by a variety of manufacturers. Featuring high specific output and robust construction the LNF has proven very reliable both in street use and in racing use, having been used in the highly successful Chevrolet Cobalt racing in Grand Am’s endurance series. The engine is the perfect choice to provide ample power and reliability to the Supersport!

Engine, Clutch, and Transmission Installation


After the cars are plumbed, wired, and the brakes and fuel cells added, the brand new General Motors 2.0 liter,turbocharged, direct injected LNF engine is installed in the car by our very experienced racing technicians.

Brand New GM Ecotec Engines

The Supersports have arrived from the factory at 999 Motorsports. We will take you through the steps that 999 Motorsports USA goes through to complete the cars and deliver them to their new owners.

The powerplant is the General Motors Ecotec 2.0 liter LNF engine. We use brand new, from the factory engines in our cars. The photo shows the three engines and transmissions as they are uncrated and awaiting final prep and installation.

A potential customer toured our facility, saw the engines lined up and commented that he assumed we would be using junkyard engines, not brand new powerplants. All the components used on the Supersport are brand new, from the factory parts. Even the bolts used to attach the accessories to the engine are General Motors OEM bolts, ordered by the GM part number. We could save a bunch of money buying bolts from the national giant hardware supplier but they would not be exactly what is called for by General Motors.

As we proceed through the assembly process we will show the high level of quality of parts as well as quality of construction of the Supersport!
