[DeTomaso] Other Aero Issues

[Patrick Hals]

Please do continue this topic. 
I am in full preparation of Le Mans Classic for Candy 2862 GR4 factory car, and everything I read on the Forum is highly interesting for me. I am extremely concerned by temperature aspects, drag, grip, downforce,... 
If you want to see some pics of Candy testing at Spa last Tuesday, click on http://www.pistenclub.de/
Thanks to all.

  I've also heard that the Indy cars are working with the tire manufacturers to produce dimpled tires. Preliminary tests with re-treads applied to the tire walls have been very positive.

    I suggest that you do the entire car in a dimple finish, similar to a 
  golfball which has been scientifically proven to reduce drag. I would pay particular 
  attention to the underbody surfaces and all areas that lead into the radiator 
  opening. Considerable reductions in drag can also be realized by dimpling 
  surfaces of the suspension, springs, a-arms, etc.

  Wheels and wheelhouse inners can also be done as this is a very important 
  area since there is a lot of turbulence and increased drag caused by wheel 
  rotation.

  You should also tape up any body cuts and reduce the radiator intake to as 
  small an opening as possible. If you have a fan shroud you can compute the front 
  air intake and close it off to match that in square inches.

  It is too bad that you do not have a way to measure all of this but what the 
  heck you already know it is in the right direction.
