528i Gettin Fishy

[tacroteau]

Hey guys/girls. I was cruzing on the highway in light rain the other day doing about 75 for an hour or so. Out of no where the rear end started to wobble from side to side. It was so bad I pulled over, I thought the frigin thing was gonna spin out on me. No traction control lights or anything. It did it for a few more miles (at 55 mph) and then it was fine. Any ideas?

Also I am running very low profile tires on a set of 19x8" rims. The camber and toe of the wheels from BMW seem to set the rears inward and the front outward, is there a reason for this, because I know it dosnt give much contact area, and severly increases tire wear.

Any thoughts would be appreciated...

I guess this smaller surface area of contact could be an issue. There are probably a few things affectign it. One being the surface area. Another might just be the simple fact of a RWD in the rain. Small little curves/bumps in the roads with light rain can be dangerous. Did you notice it was sliding out under acceleration or anything like that? Also your tires may be more just dry tires and not well suited for rain. Also, did you get your tires/suspension alignment?

Good Luck & Drive Safe!

It's also possible that the lugs on your hubs are working a little loose. How bald are you?

well, the size of your rims might not be what the BMW ASC system is designed to handle, if thats the case, then you're kinda screwed unless you can find a way to get the traction control system to work with your new wheels/tires

ASC is not intelligent to know what kind of rim is on there... 19s or 16s... same thing if the overall diameter is same.

It's probably some ultra-high dry performance tire and is not getting much traction in the wet. Check tirerack.com for ratings on your tires.

My dad is losing his hair, but so far mine is holding up very well, thanks for asking. (i dont know how this will affect traction)

P.S. that was my first thought, lugs are great.

That's what was weird I was set on cruise control, smooth highway, and I havn't noticed it since. Just weird.

Umm. I meant the tires.

Your rear ball joints are shot. Replace them & you'll be fine
