Going with koni sports, swift springs, and M3 control arms. Do i need modified bump stops or is it not required? Do i need anything else that i may be missing?

Have koni yellows myself. I put the dinan bump stops on and I feel it was necessary. Definitely more necessary in the rear though. I think I could have gotten away with stock in the front. You could just leave the fronts stock and trim an inch and a half off of the rears. Getting the Dinan's is the best option though.

I was in your same situation; trying to figure out if I needed them. Some people said it rode fine, some people complained they were riding on them. I decided to be safe and get the shorter ones. Save yourself a bunch of money and get the oem parts:

Insane when inflated OEM parts prices are considered cheapest option.

Same bumpstopd for the F32 coupe?

[atam1980]

The above numbers are right for the F32 335i coupe. You can literally see the part numbers for the front bump stops in Dinan's product photos.

For a F30 335i, the part numbers are

Front: 33536784122
Rear: 33536762722

I went to getbmwparts and entered those parts number and it shows that there left and right option? I'm assuming that I have to order 2 of each.
Those parts number is the yellow bump stop but do i need to order the 2 black dust cover part#33536758557 or do I reuse the ones that came with my car?

Front: 33536784122
Rear: 33536762722
