> front wheel drive...the anti-roll bar lifts the left rear wheel off the ground
I lost two friends in separate crashes in a Honda S2000. Yes, it is normal for the inside rear tire to lift off of the ground, but the problem is that Honda decided to create a rear-wheel drive car. Despite having no experience with making good cars, they still decided against hiring competent people that had experience with designing suspensions for rear-wheel drive cars. They produced a death trap. Since they were too cheap to put in a limited-slip differential, the rear inside tire is given 100% of the torque when it lifts from the ground. When it returns to the ground, the force tries to push the car straight. Lifting the rear wheel, as you noted, is completely normal. It was their incompetence designing the rest of the car that kills.
I worked IT for a chain of car dealers that included a couple of Honda dealers. One of my coworkers had done hundreds of test drives in Vipers in our Dodge dealership because he was a former NASCAR driver so he was our go to guy to sell that model. He died in his second test drive in an S2000. The passenger's description and the small amount of rubber left on the inside curve just before the car veered toward the outside of the curve proves Honda's incompetence killed him.
