World & Australian Speed Record Attempt

After consultation with the Confederation of Motor Sport (www.cams.com.au) there may be up to 8 world and Australian speed records the Redback Spyder claim.

Discussions with authorities to gain access to the Woomera Testing Range or Lake Gairdner in South Australia as th eliley locations for such attempts are progressing.

However this sort of endeavor is not cheap - there are FIA fees, CAMS fees, insurance, stewards, scrutineers, timekeepers and judges fees.

And that's even before we have put the Redback on the truck.

Beyond Tomorrow Productions, Channel 9 and Channel 10 have expressed interest in covering the speed record attempts.

If you have a few spare dollars and would like to get some recognition and national media exposure for helping a dedicated team of aussies show the world how things are done down here, then contact us for more of a chat.

Of course flat out top speed is all about gear ratio selection. Here's what we are planning for the world speed record attempt.

The theoretical maximum speed is 350Km/h
