Hi,

Your plan regarding the camber settings is sound. My advice is to make 
small changes and measure and make sure to "settle" the car between 
reading to make sure you don't over-shoot the target numbers.

The rear toe, on the other hand needs to be addressed. With those numbers, 
your "thrust angle" has to be wrong. Even though the total toe-in is 
small, the +.24 on the driver side seems excessive. So, you might want to 
address that. Keep in mind that the TR6 IRS toe in increases as the 
suspension compresses, so don't go crazy here. But a quarter-inch toe out 
on one side is going to translate to EVIL handling.

The other part of your plan concerns me. If you try to get the car flat 
and level with no driver, the handling is going to suck. That's because 
you're going to throw out cross weights for "curb appeal". The TR6 with 
LHD has a considerable weight bias to the left side of the car, so you 
want to accomodate that in your eventual ride-height and camber / toe 
settings.

But if you don't "drive" the car, ignore the weight bias thing even though 
you can make the car a dog to drive.

I'm just sayin.

Regards,
rml
