|November 8, 2008 - After some rough sketches and much thinking, I'm leaning away from narrowing the Miata suspension.|
The roll centers won't be as well controlled as I thought - thanks to Jensenman on the GRM forums for making me take another look at this.
Luckily, there's an alternative. The fender flares from a Dodge Omni can be grafted on to the MG bodyshell, adding a bit over 2" per side. That should be almost perfect. Time to start hunting Omnis, or see if I can find another car that would make a good donor.
