As you know the rear engined 911 style engine placement is actively trying to kill us all. I tried to find a book or a website about driving this configuration of car but came up empty handed, perhaps I did not look hard enough.
What I found in real life ( where you have no UNDO ) about driving the IM was the the weight of the engine is high enough that it feels like the car is going to roll rather than skid. I was eventually able to get the back end to skid out, but it does not feel solid enough to really push it. We are going to look into front and rear anti-sway bars to see what effect they will have.
I have found though experiene that when I'm in a tight fast corner if the car feels a bit wobbly you just have to tap the throttle and it bites into the road, which is counter to all of my normal driving exprience, even with my mid engined MR2. It takes some getting used to, since with front engine rear drive cars that would be a good way depart from controlled flight.
The tires have really good grip and the brakes are good, you just have to really stand on them. I have not been able to lock them up so I always wonder how much more there is. The rack and pinion I have is not standard, and I find the steering is very good. It feels a bit heavy at slow speeds like all manual set ups but feels very good right at speed. At speeds about 90 mph the car starts to feel a bit light and is too affected by road surface, not exactly bump steer, but not as sure footed. Above 110 mph it is happiest going in straight lines or very gradual turns, if the road is turning in but banked out you feel like you really have to bleed off some speed before going in. You need good control of your sphinkter muscels for this manouver. IM are tightening up the front end and we'll see how that feels;... for the car, not my butt.
I went for the leather Nardi wheel rather than the wood one. I like to drive rather than look at the car, so I find the leather wheel gives me better grip and feedback. I also went for the Nardi anatomical shift knob, which I really really recommend. It has some flex in it so you can really drive it into the gate and it gives once it hits the stop. Henry and I are still bending the shift arm around to find the perfect place. I'm 6'4 so we moved my seat all the way back and down, and the shifter originally was so close to the wheel that I could not get my knee though. We moved it over 2" but then I could not get it into 5th gear with the baby seat in place or get it into first because my elbow was against the back of the seat. I was getting car-pool tunnel syndome from my car. We have a plan for the final position, but the shift knob made a huge difference.
So there, the car is good and will be great soon, all freshly repainted and good to go.
