Yes, I did. I apologize.

I had previously listed my suspension setting backwards. I always screw that up and want to make the higher settings stiffer.

They are set to 2 rear and 3 front.

My car was slightly out of alignment, and my rear sway was set to full stiff.

The rear sway was moved to full soft and the car was aligned The car has some understeer now, but is more predictable and the wallowing has been pretty much eliminated.


I think my weak link is still the tires. No one else runs these Dunlops and it's probably for a good reason. I just can't seem to wear out those damn fronts and I'm too cheap to throw away perfectly good tires I will give it one more set of rears and then they go in the garbage and all four will be replaced with real tires.

I was autox'ing today and the car felt great. Very stable and predictable with a bit of oversteer. I ran the tires at 33F and 40R (cold). They do start to howl when at the limits. I'm not sure if that is the compound or I should lower the pressure.

I have a DE at Sebring in two weeks so I'll be curious to see how it works out there.

I like the stiffness of the suspension setting. I don't drive it daily and it's fine for short trips. I still need to get these sway bars figured out. Is there a general rule for what happens when you makes these adjustments (ie soften front and stiffen back, etc..)?

Also, what speed rating are the Dunlops? What you describe can also come from using a lower speed rated tire than what is needed.
It's a Z rated tire.

Here's a link to the specs.
