I'm pretty sure I'll be doing the same stuff to my 1 when I buy it. This is a very interesting thread for me.
will had the best prices and best customer service of all vendors i talked to.

its a nice set of upgrades. i will say that the ride is firmer than i expected, but i live in a part of houston that has terrible roads. the suspension travel over wavy roads and bumps is totally fine though, no issues there.

On most decent roads you hardly notice any loss in ride quality, but on bad roads you certainly will notice that its less compliant. At least the car feels connected to the road, more like a sports car now, which it didn't before IMHO. The rear of the car feels much better controlled than before. The turn-in crispness has been totally transformed from stock. M3 arms and PS seem to compliment each other very well. I think this is a great upgrade for the 135i.
totally agre with your assessment. i too was surprised at how firm the car rides, but its nothing too bad.

i will probably not run re-11s again on the street next time thoguh, ill look into s04 or possibly PSS tires to smooth out the ride a bit.
