cougar reversing rear wishbones
 

Guys

I see most of the team are running the +8mm chassis in either carbon or alloy style, but are moving the rear arms forward 2.5mm so roughly changing the wheelbase by 5mm or so.
Has anyone tried the standard chassis but reverse the rear arms to get same effect?

if you reverse the rear arms, you will get less weight on the rearend, with a +8mm and moving reararms forward you get more weight on rearend. At the Euros in 2010 many drivers was using standard chassis and moving reararms 2mm forward to gain more rearend grip

Yes and works very well!
