KW Suspension Help

jliffcones · 02-14-2021, 10:29 AM

Hey guys,

I recently bought a BMW 335D with a set of KW coilovers on it. I can't find any information on the part number. The suspension rides good on a dry road, but when its raining it feels EXTREMELY unsafe and moves side to side quite a lot. I am wondering if the suspension needs to be rebuilt.

Part number for the KW Coilovers is 353 20 317.

I am also putting on new 265/30/19 tires on the rear to see if this helps. The tires definitely need replacing.

Any help is appreciated!

I'd be looking at your suspension bushings, first.

If it's only in the rain, new tires might be all you need. I had bad floating on wet roads once, turned out the rear tire tread was much lower than I expected.

This sounds like a tire and possibly alignment issue. Nothing more.
