Roll Center design theory

[Salt Racer]

...what are some simple tests that the basic guy can perform in order to tune and get a good definition of how well your car handles?....Are there any others that would help?

Like others have said, go to the track. You'll never find the limit on street, and only at the limit you can really tell how your car really handles.

Looking at pics would help as well. There is a current issue of PHR floating around in office, and I think it's the pic of your car on the page of bumpsteer article. Look at the front tire - lots of positive camber and fair amount of sidewall deflection. Deflection could be either due to insufficient pressure and/or the construction of the tire itself, or the rims are too narrow for your tires. Excessive positive camber suggests you need more static neg. camber and/or revised geometry. Increased caster will help as well.


Marcus,
Please post the numbers you're getting. You can also get Dennis' pickup point numbers somewhere in his website, so try them on your software (Dennis uses freebie Perf Trend, and I use WinGeo3). I should also note that Dennis has SCP UCAs. Length may be different from OE arms, and UBJ offset is different for sure. He initially had like +14* caster.
