One other point on these tires, I am thrilled with my choice and the handling for me is great, my recent ticket (first in 17 years) has clipped my wings a bit. They are softer and smoother than stock (a very good thing) and handling is as good as stock? (may be a little less crisp, IMO steering response is better) but if you need track-like performance or very sharp reflexes you will be better served with NRs BFG choice. Remember the Contis are not aggressive either. It all depends on your needs, I needed to get the unruly suspension under control not Z rated cornering or speeds (they are H rated btw, 4mph above the limiter). For me, in this car, I would not have any other tire than the ComforTread, this illustrates how vexing the problem was. As I mentioned, the steering kick is now tolerable but unfortunately not banished like the awful rear end problem.
I want to reiterate the difference in the rear end jutting and kicking out. It is 100% GONE on all sorts of bumps and irregular pavement with new tires only!!! Seems HEMEEE has similar results with tweaking the suspension and stock tires. HEMEEE, do you havs self seals? This confirms my suspicion that more than tires are at play here, shocks, springs, tires etc. Changing one or more of these components may result in dramatic improvement in the rear kick out on bumpy curves and rear flick in straight bumps. Something back there is underdeveloped and I think the Contis exposed the problem, GY and others mask it. Leave it to Chryco engineers to select probably the only tire on the planet to bring out the worst in their suspension design. Yes the 98-03 E class, modified, carrying an extra 500 lbs, and all that excessive unsprung weight. Seems the SRT8 boys got it right as we don't hear the same complaints from them.
Meister, a few weeks after I bought my C (6/26/04), I contacted a supplier for steering stabilizers, no luck. My 87 300E had a steering shock absorber like some heavy trucks. This was a recirculating ball system, TMK I don't know of any stabilizer systems for R&P steering. NE1 else know about this? I think a steering shock would eliminate any remaining kick, maybe it's time for a little research.
