@bugger06 (1/2) In wind tunnel testing you are trying to control variables. We take out the shocks and springs so the car is only being held by ride height actuators at all 4 corners of the Chassis (frame). The actuators and wheel rollers are connected to a 6-component balance (scale) that measures forces in all directions. These (like most racecars) cars are very sensitive (aerodynamically) to height changes.
(2/2) Different rate springs will change the heights and in order to make certain you are testing a specific height we control that variable with the ride height control system. Teams can run ride height maps (different heights) to find out what attitude they want to run (aerodynamically) and then they work with shocks and springs to get the car to that attitude on the race track and work mechanically.
@CarBizIndio If you are talking about the sticker on the Right Front (RF) see 2:55. The tire is marked "RF Wind Tunnel”. It’s just a sticker you see on the rim that is the same sticker for that entire brand of rim. If you walk to the other side you will see both arrows in the forward direction. This is so you don’t have to have left and right side rims.
why does it need ride height control? i would of thought the wind passing over the car would do that for you.

@A2WindTunnel ok cool thanks heaps, i understand now.

good job at running a directional tire the wrong way at high speeds

@CarBizIndio That is just the Aero racing wheels logo, has absolutely nothing to do with the tire or direction it should spin

somehow I enjoyed watching the tire spin more than the wind tunnel lol
