Default Re: 911 Platform, Is It Forgiving?

Hello All. My first post on this great website.

I am also a change over driver from the 987 platform to the 997.

My car is a 2008 911S with pretty much a completely adjustable suspension: Bilstein coilovers (PASM compatible), two piece LCA's, TPC sways (5/4 adjustments). Tarrett links and toe kit, dog bones.

I had a very nice setup on my 987 RS60 Boxster and was very confident in the car. During the period where I way getting the suspension setup (this done over many DEs) I had a temporary period that gave me snap oversteer, which was very unnerving to say the least!

It was at that time that I realized that a mid engine car is not only very neutral to inputs, but that it will also rotate quite freely once the limit is reached.

Now my track days are in the 997 platform: I initially felt that the tail end was way to influential, especially at higher speeds. I had the corner weighting changed to get the back end down a little and now even with crappy street tires (PS2s) the car is just a second or so slower than the boxster was, even though the Boxster had DOT comp tires and race seat and restraints. (these two items: tires, restraints are good for about 4 plus seconds a lap by my estimation). I can throttle steer the car at both low and high speed. The car settles in just fine powering through apexes.

I have quickly forgotten that the engine is "way back there".

The Boxster was lighter and the 911 has more power but I think that is pretty close to an equal trade off.

Engine HP on the Boxster was 325, and the 911 is about 375. Boxster wieghed 3000, 911 weights just under 3200.
