Tunnels for DSR & CSR Cars

Lee Stohr Cars is producing new molds for Lee's newly designed DSR/CSR racer. Some of the parts on for the new design cars may fit the older Stohr cars. Les says, "Last month we built a new 'tunnel' floor mold. John Hill fitted the first floor to his DSR and dominated the Thunderhill Double National last weekend [in California]. He lowered the track record by 2.2 seconds. This was the first time out with the new floor, and with testing it will only get faster."

Tunnels are not new this year to the sports racer classes, having been seen on various car at the 2004 SCCA Runoffs. Tunnel were used on Jacek Mucha CSR converted from a Formula Atlantic Ralt, on Loyning's Championship CSR converted from a FA Swift, as well as on John Hill's CSR/DSR Stohr and Bill Maisey's DSR Cheetah.

Lee added, "Our floor design is based on the old Group C/ GTP tunnels. Those shapes are in the public domain, and not patented. Some Stohr owners have already built their own tunnel floors.

I have a proprietary drawing produced 2 weeks ago which defines my actual floor part. An engineer must define ply number, orientation of fibers, core thickness and density, among many other things. I am not aware of any other DSR manufacturer with such a design or drawing.
We have sold 5 of my new floors as of today. For the lap time gain, it is far cheaper than a hot engine.

Now that the SCCA has approved ground effect downforce in CSR and DSR, it will be hard to win without it."

Lee Stohr Cars is also offering a revised front splitter/diffuser, carbon fibber rear wing, and suspension control arms with improved geometry for his new design, as well as for previous Stohr designed cars. For further information contact:
