Wouldn’t it make sense that the ramp angle in the diff controls the slope of the transient conditions on the graph above?

Good tires hide many things....

Post by funwithmonkeys » 05 May 2019 20:31

I have been working to get my suspension sorted out again after changing most of it last year. Shortened struts, moved the sway bar and it has not had a proper alignment since the front got mashed in. Well this weekend I finally did it all. I got the tools and did a proper alignment. It took about 3 hours to get it exactly where I wanted it then I had to go through the corner weighting process again. All told I spent about 7 hours on it but man was it worth it.
My car has always handled well...I can keep it glued to Kieth's bumper through the twistiest roads, but lately I have felt like it should be better. After the accident it didn't feel as stable at higher speeds and it has been down right eating tires. I guess having R compound tires can hide a lot of issues. I don't think I would have been able to drive it that well if my tires weren't that good.

I started out taking readings of the toe, camber and caster. Toe I had corrected a few weeks ago and it was at dead on 0. Camber was at -3.5 on the drivers side and 4 on the passenger. The caster was where it was really messed up. I am guessing the pull that Tyson did to straighten the front out changed a few things. Drivers side was at 4.5 and passenger was at 0.25. I find it hard to believe that it didn't handle worse but it does explain why that tire was getting eaten up. I corrected the cambers to 3.5 on the passenger side and set the caster to 5.25 on both sides. I took it for a drive right away and the difference was astounding. I had forgotten how good it could handle. No more sketchiness at high speed.175 on a road that is bumpy and undulating and she was dead straight and stable as can be. It actually felt better than it normally did at 120.

You can see that two of the tires are almost new looking and 2 are pretty worn.

Of all our suspension setups.....UNEQUAL castor is the worse...and yours was HUGE! Good you checked and found that.

Good job getting that sorted. I think we are all guilty of putting off things like proper alignment or engine tuning in lieu of bolting on a fancy new part, but its the things like this that turn a decent handling or running car into an amazing car! There are so many things that I have put off over the years that once I did them I wondered what took me so long.

Wait what happened to the front of your car? I don't remember reading about that.

A moron backed into it in the ferry line up.

I still have nightmares envisioning being strapped in as the truck backs up towards you with no were to go.
