Sport II for CSR

December 18, 2004

Aurora Motorsports will be importing the ADR Sport 2. All of the first cars will come with Hayabusa engines with paddle shifters, drive shaft, differential, mechanical reverse, larger F3000 wheels and tires, light kits, and some new chassis changes. Later the cars will be offered with a Honda B16 engine with Hewland gearbox as an upgradable option. These cars are very nice with a lot of F2 and F3 technology.

Rod Whedbee of Aurora Motorsports has ordered two ADR Sport 2 cars from ADR Engineering, UK. will be racing one of the cars beginning in February 2005 and the 2nd car will be available for sale to the first US customer. Both cars are in production and will be significantly less than a Radical. Pricing is available upon request.

The Sport 2 "only weights in at 411 kilos (904 pounds). Even with a 200 pound driver we will have to bring the car up to minimum weight for CSR. This allows us to move some weight around and put it where we need it. ADR had also already engineered the Hayabusa powered car and we were ready to proceed in getting the cars to the US. I've also been working with SCCA on getting the first cars homologated," reports Rod Whedbee.

"We have delayed the first couple of cars a few weeks while the chassis jig and new body is finished. We felt our customers would rather have the 2nd generation Sport 2.

The chassis changes included adding a few bars to increase strength and changing the roll hoop to a lighter and stronger material. If you look at the CAD drawings [on the right] the bars in [medium] green were changed. Also the termination points that are open [at the rear] are where the bulkheads attach. The rear bulkhead is changeable to accept either the motorcycle rear end or the FTR gearbox for automotive based powerplants. Our engines are built here in South Carolina at KWS Motorsports."
