Steve - UK,
Thanks for the compliment! I too love the look and feel of this setup. I have a much harder time breaking the rears loose from a dead stop now. And when I do, they hook up quick.
As to any rubbing... The fronts only suffer very light rubbing at full suspension articulation (up) in the front. They rub every so slightly on a fender bolt that's at the top of the inner lip. Can't change it short of removing the bolt and trimming the inner fender area.
The rubbing is so slight and only at full articulation in the up direction that I've left it alone. Doesn't damage the car or the tires from what I can tell.
In the rear, I DID have to add a 4mm spacer to offset the rubbing at the upper, front, inside wheel well wall area as almost any upward articulation of the rear suspension was rubbing there. I let it go long enough to rub away the undercoating. Since the addition of the 4mm spacer (not in the pictures above), I have had no rubbing at all in the rear.
Now I just have to shoot some new undercoating on that area...
Cheers!
