2012 Z4 35IS Suspension upgrade

Just finished upgrading the suspension and wheels. Went with BCRacing BR coilovers, Beyern Spartan wheels, PSS 275/35R18 and 245/40R18 tires. Had factory 19" wheels that kept getting bent on every hard bump.
Amazing difference in handling and ride. The front end use to feel like it was floating and not wanting to turn. Now it feels planted and ready for the turn. Can't wait to take it to the track. (Texas World Speedway)

Also, has AFE CAI, Wagner FMIC, RB turbos, ER Charge pipe, AR catless downpipes and Cobb custom tune.

My 35is even on PSS still rides rough over expansions/bumps how much harder is your car riding now? I cant imagine stiffening the suspension past stock for a DD.

Throw in the Luxon front brace and you'll feel the difference in steering response. It tightens everything up nicely.

I actually think the car feels smoother but certainly not any rougher. Part of it might be moving from 19" to 18" wheels or that my 19" wheels were pretty dinged up and had some vibration. I also went with the Swift springs. I also forgot to mention that we went with -1deg of camber. The front end is quicker but still tracks center pretty well.

Is anyone else chewing up their rear wheel well liner?

I am on the 35is stock suspension. I have my wheels pushed out nicely.

I am rubbing the plastic wheel liner on aggressive driving. Those of you that have lowered even more how are you not hitting the liner?

Maybe my liners just are not installed correctly and are too low??

How is the street comfort as DD vs stock?

How wide did you go on the wheels?
