Got an older BMW with original discs worn out. Don't want to spend a fortune, but also don't want cheap junk that'll warp in a year. Looking for decent mid-range options that fit well and perform reliably. Suggestions?

For older cars, mid-tier coated or vented discs are usually the sweet spot- better than budget but not crazy expensive like big-name performance ones. I replaced mine last year with some solid ones that matched OEM specs perfectly. This site https://elartcom.eu/categories/brake-discs-2 had a wide selection in that price range, including vented types with rust protection. They've held up great on mixed driving, no vibrations or fade. Just torque everything to spec and use new hardware if possible. Good balance of quality and cost for non-sporty use.
