Suspension and brakes

Only a few things to do on my 335. Need to do suspension all around, brakes and dv/bov. For suspension I wanted to go koni yellows, should I buy a full refresh kit on fcp while I'm at it or can I buy a kit that comes with konis from somewhere. I'm going to just get regular rotors but I have hawk pads from previous owner, are they worth the money only being fbo at 17-18 psi if not what do you recommend.

What is full refresh kit?
I would choose my own parts. Definitely go M3 control arms from TRW. Do schock mounts in the back from Monroe (uber cheap). Do rear subframe bushings. Go race or solid.
IMO I would go Bilstein instead of Koni.

Koni sports are a good choice. Being adjustable (fronts are very easy, rear more of a pain) is a nice feature. Most people initially adjust till they get where they are happy and then leave it. Also, on the E82 at least, the B6 vs B8 'controversy' got frustrating. And Koni's will be a little more comfortable for everyday driving.

Get the right bumpstops for your springs. I won't give you the parts I used because it probably is different for your car.

Already has m3 parts, was more referring to the shock mounts and hardware

Pretty sure they are h&r sport springs I'd have to find out, any way to tell just by looking at the spring? I was looking at the shock mount kit from fcp, would I be able to cut the bump stop or is there somewhere specific to buy them from if they haven't already been replaced

BMW OE springs are black and have an alpha-numeric code like D7. Fronts have the code on a tag, rears have the code painted on. I think H&R springs have H&R and a part no on them, but, it may be worn off.

As far as bumpstops, people do cut them but if you're refreshing suspension it's best to replace the bumpstops. They deteriorate.

Hopefully someone will chime in with what to look for on the springs and what bumpstops are best suited for your setup. Sorry I can't be of more help.
