In 1994, Grant Watson was offered a drive of a Sports 1300 at Lakeside Raceway. The car's owner, Tony Jewel, was stunned when within a few laps the car was circulating at near track record times. It was on this day that Watson's old adage "Dirt's for Racing - Bitumen's for getting there" changed.

This experience prompted Grant to design and build his own lightweight racer, using efficient aerodynamics to help overcome the limits of the small 1300cc motor. His first car was named the Esprit and it rolled out of his factory in 1996.

After a successful introduction to Sports Car racing and constant research into increasing the performance of his first car, it was back to the drawing board.

In 1996, ProSport Developments built Mallock Mk31 race cars under licence from Mallock in the UK. These cars were specifically built to race in the CAMS Sports Car Class and several are still being competitively raced today powered by front mounted single cam Suzuki and Toyota car engines. The most notable car is Supersports Club President, Richard Crawshay who was the runner up in the over 1320cc Championships and Neil Kenny another extremely successful competitor in his Mallock Mk 31.

By late 1997 the knowledge base within the company of circuit track racing and track car construction was well and truly harnessed. The days of winged sprint cars and high horsepower was to form the basis of the companies next creation. Put simply, better aero and more power.

Aerodynamics was the key, and it certainly showed on his next car, the Pentium. The striking shape of the Pentium, complete with high F1 type nose to allow better cooling as the air now entered through the front of the left side pod into the small radiator. The need for more efficient cooling was a must with the now larger and more powerful twin cam Suzuki engine. Packed with many innovative ideas and awesome ground effect aero, the Pentium won the 1999 National Championships at Willowbank in Queensland with Watson at the wheel.

In 2001 the Pentium was sold to George Davis in Sydney. George took out the the NSW State Championship in 2006.
Next came the ProSport Evolution, a serious race car which combines cutting edge aerodynamics with an excellent power-to-weight ratio.

Aggressive and responsive, the Evolution is truly a driver's car. It represents the end result of more than 20 years experience racing and building high performance cars.

Grant Watson’s company ProSport has an ongoing development program, and hence the logic behind the name “ Evolution” for his current race cars.

Grant has already started his new project, with a totally new concept in race cars design to be entered into the 2009 season to really shake up the establishment.

Recent Results include:
1. Francois Jouy in 2008 currently leading the NSW Supersports Club Championship and virtually can’t be beaten this year. in his Evo 3 Mulsanne.
2. Grant Watson in his Factory Team’s Evo4, is leading the 2008 Qld Championship with one round to go.
3. Prosport have won 4 NSW State championships.
4. Grant Watson has won 3 Queensland Championships and 2 National Championships in the last 9 years.
