Supersport Mk2 Rotating Weight Improvements


There is an old adage in racing concerning parts weight that goes like this, “Light, strong, cheap, you can only pick two”. The Supersport having been designed with strength and safety as the main priorities was admittedly not the lightest car on the market.  At approximately 2300 pounds it is lighter than the IMSA GT cars so it is not heavy by any stretch.  Rotating weight is an area of particular concern on any race car.  The energy required to speed up or slow down the rotating weight can have a measurable effect on overall performance.

Two areas that have received particular attention in developing the Supersport Mk2 are the brake rotor and wheel combination and the clutch and flywheel package.



First the brakes.  Everybody that has driven the Supersport has been impressed with the braking performance.  The large 6 piston Wilwood front calipers and the 4 piston Wilwood rear calipers provide plenty of stopping power.  Brake control is positive and no fading was ever experienced.  The one fault that appeared was premature rear rotor wear.  We decided to improve the brakes by using Wilwood’s Premium Spec 37 iron discs mounted on aluminum hats. The new Wilwood discs are a very high quality material providing better cooling and have the added benefit of being lighter than the original rotors previously used. The front rotors are 4.8 pounds lighter and the rears are 2.2 pounds lighter.  Coupled with the new larger but lighter wheels the total savings in rotating weight is 15.8 pounds.  This savings has a cost but we chose light and strong over inexpensive and heavy.



Secondly, the clutch and flywheel.  With the change to the 3 MO Performance transmission a change to the clutch and flywheel was necessary.  The original OE flywheel on the LNF engine weighed a whopping 32.4 pounds.  We had already changed to an aluminum flywheel that with the OE type clutch brought the weight down to 21.6 pounds.  Now by again choosing strong and light over inexpensive and heavy the new one piece steel racing flywheel and Alcon clutch weigh only 14.4 pounds. This weight savings is all rotating weight at engine speeds.  The huge reduction in MOI will have a measurable effect on the performance of the Supersport Mk2.

The final touches are being put on the Supersport Mk2. Appointments to test drive this amazing new car are available!


Supersport Mk2 Development Update

The Mk2 development of the Supersport started with the need to improve the driving experience and do away with the unsatisfactory shifting and performance caused by the OE GM 5 speed synchromesh transmission.

With the decision to switch to a proper racing transmission, the 3MOP dog engaged sequentially shifted 6 speed, it only made sense to include no lift upshifts which lead to auto blip downshifts, and then paddle shift controls. There was no way this could be achieved with the OE electronics. We began our search for a true race quality ECU. After several starts and stops we have selected Life Racing to be our electronics technical partner and supplier. Life Racing is represented in the US by Chris Muzio at DanZio Performance. Chris is proving to be our ideal partner. His expertise with the Life Racing products is giving us results exceeding our expectations.

While our search for better electronics was taking place, other suppliers were continuing development on the Ecotec platform. We made the decision to change our engine supplier to ZZ Performance. ZZ Performance had begun to offer a new Gen III version of the LNF engine that has been the heart of the Supersport. The new European sourced engine uses a stronger block for more reliability, larger injectors, and a revised fuel rail. ZZ Performance adds a Borg Warner EFR turbo custom fitted to the engine and we add the ZZ Performance reground fuel pump cam to boost GDI pump output. This combination when coupled to the Life Racing ECU takes our power plant to a whole new level. We have developed two tunes which will be easily selected and included with each Supersport Mk2. The base tune running premium pump gas produced 360 hp at 6500 rpm and 305 lb./ft. of torque at 4700 rpm. The high output tune which requires using VP MS-109 fuel makes 430 hp at 6400 rpm and 385 lb./ft. at 5000 rpm. Both tunes are incredibly safe with a large margin of safety. The engine simply runs and feels like a true race engine while still being easy to operate while driving around the pits.

The Life Racing ECU is also handling the transmission control commanded by the new XAP Electronique steering wheel, fitted with carbon paddles actuated by the XAP E-Shift 2 electronic actuator. This new package using these top of the line racing suppliers is giving the Supersport Mk2 the feel of driving a highly refined true GT race car.

“Performance on par with a GT3 Super Cup car for less than half the price and 10 cents on the dollar costs to operate” is our mantra for 999 Motorsports USA. The Supersport Mk2 is achieving our goals.

Test drives for prospective buyers begin at the end of July. Contact 999 Motorsports USA to experience the thrill of our year long project, offering the best driving experience and the best value in racing.

Supersport Runs Road America!

Supersport owner Cal Kalishek loaded up his car and traveled to Road America for three fun days running the iconic three mile track located in Elkhart Lake, Wisconsin.  Cal’s brothers Rob and Charlie and Rob’s sons Nick and Kurt all brought their track day cars, making it a family reunion as well!

Cal choose to run with Group 2, a V-8 powered group so that he could run against his brother in an ex-Bondurant Mustang Cobra. He reported that there were three Cobra kit cars in the group and the Supersport blew the doors off of each one of them. As Cal put it “Three days of high speed thrashing around Road America’s three miles turned out great!”.

Needless to say, it’s great to see Supersport owners out running hard for three days and having a great time!

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.
