My cars pretty low was wondering how often do you guys run into suspension problems yearly

 

pretty vague question. If you're setup properly with good coilovers and your alignment is in spec then your only problems should be scraping the ground occasionally.

 

Only problems i had were in the front.Rear never had a issue after rolling fender lip.
I went threw upper ball joints every month or two. constantly hitting sub frame on the ground on the highway going over bridges and simular splits in the road which ended me with a trashed cat.
also when low i backed my car up on some uneven grass and the bumper got caught and ripped half way off the front.
i spent unnessary money fixxing bs just trying to be low..
lesson learned for me.
any lower than 2" you will start to have problems.
