I\'m guessing it\'s the splitter you\'re talking about.

Ply is very commonly used for splitters on proper track cars :)

Cheap, easily formed, reasonably tough, and expendable.

EDIT: unless you mean on the driver\'s side here:

In which case that\'s ducting.

the ply looks to me like ducting for the rad. and would probably have been mocked up before making in metal as rob said. There isn\'t really anything there to shield is there?

Its ducting to the rad, ply is used as its cheap and easy to work with, as SiH says its used a lot on race cars for the same reason.
 
We dont need to heat sheild anything on the hot side as its N/A with a ceramic coated manifold that traps a huge ammount of heat.

ah i see thanks matt did wonder the cars wicked mate really like it just wondered what it was for not taking the .... i thought all that 3 rotor carbon ceramic coating youd have gone for carbon but i suppose ply is the next best lol

Post by: mattfduk on January 09, 2010, 08:55:00 AM
Carbon is £350 a sheet and ply is £20 so unless I get something very cheap it stays ply!

Speedhunters have just provided a perfect example of why unless your a fully fledged team with cash to splash, then plywood is a more sensible option than exotic materials such as carbon fibre:
