You will never notice any brake bias in typical street driving conditions, so if you are not worried about running under track conditions, I wouldn't worry about it. I have 3000 miles on SPF 2378 at this time and I have no rattles and the cowel does not shake. Under hard conditions I have never noticed any frame flex with the car. Since I am a novice on the tracking of the car, some of the more experienced road racer types might be able to add some insight as to any experiences that they have had. I changed out the original suspension on the car (springs and shocks) and I have lowered the car all the way around, it is a little dropped in the back, but not much. I do not know if you can lower the car with the stock suspension. I actually went with softer springs and adustable shocks. Contrary to the Porsche 911 I own I do get more body roll, may sound a little ridiculous but I think some body role and weight transfer on acceleration/deceleration makes the car more manageable. By changing the stiffness on the shocks I can effect body roll. The body panels (doors and trunk) fit better than any new car I have bought off the show room floor, fit and finish on my SPF was excellent. The only incident I had in the SPF was running at Fernley on the long straight away, I was doing about 135 and passed a car on the left, hit somewhat of a pavement transition and the car skewed a little to the left with the rear end, quite manageable but unexpected. Overall with the changes I have done the car is great. In stock condition it still was a lot of fun but it was tough to make the car handle like I wanted it with the 15" wheels and stock suspension. As far as the other manufactures I have no experience to comment, (as far as the comparison with my 911, which has extensive drive train (409 HP, dyno'd), and extensive suspension modifications my Porsche would beat the SPF in the corners but would be eaten alive in the straights).
