I have an SL55 with RennTech mods and I have noticed more and more that under WOT the rear end wants to keep wiggling (can't think of another word) to the point where I have to almost fight the steering wheel to keep the car straight. This is not even from a full stop but any time you kick down to a lower gear, as an example today at about 30 mph to up to 100 the rear end felt like it was on ice. Has anyone else had this happen to them and what could it be?
Thanks,
Lou K

It's worth taking a flashlight and poking around back there.
We have lots of wiggle reports over here. (E55 forum)
Most of the time it is a tire issue, but we have had some rear parts fail and give the wiggle.
Look at some of the pics.

Lou , first noticed that exact thing with a friend's K4+ E55; was actually a little scary. He has replaced the rear links also and the problem is now solved

SL65
I took my SL65 to Infineon last weekend when air temps in the morning hovered around freezing. They cut the runs down to 1/8 mile because of the cold track. My tires didn't hook until the 330 mark. I have no doubt it was due to the ice cold track temps (and maybe a little too much torque)...
