I think this would be good for those on standard suspension too. Might even be a nice compromise for those who like their ride, don't want to spend the bucks on aftermarket shocks, but would like better handling... A smooth ride with better handling on the cheap
Again, a car like ours (we have functional ground effects) will benefit from lower ride height if anything from downforce... the lower CG is an intuitive benefit as well...
Best,
Phil
