Help with slushy rear springs

HI e90 SPRING CHAT

I need help with my suspension currently, I'm running 275/35/19s and I'm rubbing in the rear because it compresses so much. currently running around 8.5k / 10 inch spring in the rear. I dont know what springs i should get for the rears, im currently looking at 14k / 10inch l 16k / 9 inch l or 18k / 8 inch. Please let me know!

If anyone is wondering issue was solved with stiffer springs. Def recommend swift springs. Most e90s use 9 inch 16k if you guys are wondering!

Fender lip, it's time for you to meet Louisville slugger. Don't worry, it won't hurt much. Mr heat gun will ease the pain.

But if you don't cooperate you might have an appointment with Dr. Angle Grinder.

Already met mr fender roller, and it didnt work, it would compress too much, it looked like it is on bags when i launch hard lol. Checked my subframe bushings and they are mint, i went with 14k 10 inch springs, will let you know how well that works for the setup

8.5k is really soft, 12 or 14k should do the trick

I'm not much of a #stancelyfer, but it seems like your wheel offset/width is off, or you need some travel limiters/bumpstops. The factory wheel/suspension setup can more or less cycle through its whole travel without rubbing.

I don't remember I think it was a 19-inch 9.5 et23 or 33, something like that, I fixed the rubbing via stiffer springs. 14k springs did the job and it runs way better. It squats a lot less now, and doesn't tuck like my old spring did.
