BTW, I just completed the following setup changes in about 25 minutes:
* Widened the front and rear track widths
* Added more front in-board toe-out
* Shortened the wheelbase
* Changed the spur gear
* Changed the rear shock angles and # of piston holes open
I could have changed the lower arm roll center/dive/squat positions at the same time without adding more time if I had needed to.
And no de-tweaking of the chassis was required, seeing as the middle brace and bulkheads did not need to be loosened at all.
