asn993 > I showed how to swap the 135i pop-ups, in case anyone wants to keep them in the car. That's more for people who are doing the "front" conversion only (without the nozzle holes), and eventually want to go back to stock. It also serves as a guide on how to remove them.
The 135i pop-ups will not work with the 1M bumper. The 1M uses spray nozzles. It's a much simpler setup -- less bulky.

The 1M system is better (in my opinion), that said...I don't like the headlight washers. They spit all over the car and ruin a good wash more times than not. Really comes down to the weather in your area -- up to your discretion in that regard.
On the standard 135i, I ran VMR 710's: Front Size/Offset:18x8.5 ET45 && Rear Size/Offset:18x9.5 ET50
If you want NO rubbing, do 225 (Front) and 255 (Rear) -- It's a conservative but hassle FREE setup. If you roll your fenders, you can do 265's in the rear. I always did 225/265.
