26mm is thick. How did it alter the car?
Zero out rear toe with the 26mm and you get a fwd drift car.Like GTIfan indicated, it eliminates understeer pretty much completely. The car feels more neutral and there is less body roll.
Driving normally I don't really feel it. Making turns, in bends, it's not noticeable.
But when you drive more aggressively you definitely notice the rear come around more. It's a lot livelier. Not to the point of breaking traction (yet) but in those conditions you're a lot more confident the car is going to go where you point it.
I went towards the top end of what is available stiffness-wise because I wanted to really feel it. I daily my car and won't track it often but the sensation you get when the back end comes around that much quicker makes it worth it in the rare instances when you're really hooning it
