I have a MK3 MX5, and have had the geo set up by WIM and Eibachs fitted at the same time. Subsequently I have had the Eibach uprated anti roll bars fitted, and on the road the car is a delight, but you have to be going too fast to really push it beyond it limits, which is fare enough on the public road.
I did a trackday last weekend, and hoped to enjoy some neutral to oversteering action, only to find the cars pretty well set up to understeer, slightly progressing to neutral...all very safe etc, but hardly exiting, and not how I thought MX5`s behaved? When asked by WIM about how I would like the car to feel etc, I specifically asked for neutral to oversteer if poss.
Is this just a trait of MK3`s, given their extra level of sophisitcation, or am I going to have to go further with the geo set up to alter the characterisitcs? The car is fitted with Michelin Pilots, aswell which I am sure could be better.

Its possible that you've shifted the handling balance with the anti roll bars. Remember: stiffer ARBs aim to improve handling by reducing the grip on the axle they are fitted to and subsequently balancing the tractive effort each axle can produce. If you have made the front end too stiff, the front end will wash out.
