That doesn't sound that much different from the factory setup in
a Series 2 Europa. I guess things haven't changed very much in 35
years.

That sounds awfully familiar. The breakaway occurs about equally
on inside and outside tires. If it's the same thing that was
happening on my car, an LSD wouldn't be much help. The fix is in
roll rate balance and alignment.

I think having more than 60% of the weight on the rear wheels
might also be a contributing factor.

I think more front bar and possibly some rear toe-in (is that
adjustable on the Elise?) could be helpful. If you soften the
breakaway characteristics, the recovery may be more gentle as
well.

More front bar stands to help out there as well. Less body roll
=> tire stays flatter on pavement, more even treadwear.

I have to admit that I've never seen an oversteering car cord the
outsides of the front tires first. This is getting interesting.
Please keep us posted.
