This is funny, I was planning on writing up a big thread in the same vein. I have a 128i coupe, but looking for opinions on a good daily driver setup that tightens things up, doesn't slam the car (I drive year round), and is still supple on the small bumps but good body control when things get hairy.
I've been thinking of:
BMW Yellow Perf springs + b6 or b8 bilsteins
BMW Yellow Perf springs with koni yellows
BMW Yellow Perf springs with koni white TCK single adjust shocks
Bilstein B12
Or some other spring combo with the above?
Sorry OP, not trying to hijack the thread, just interested to hear what people have to say....I'll be starting my own thread separately
