FWIW, on turbocharged engines, one might see a significant difference in performance by changing to a well engineered free flowing exhaust alone. This is because these engines do not require as much backpressure as normally aspirated engines. Save your money and spend it on something more useful.
-
Not much different results than I stated before. Unless you are looking to alter the sounds of the car, I wouldn't waste my money on that stuff.
-
On a normally aspirated car, you'd normally loose a fair bit of bottom end torque and gain up to 5% at the top end. In order to benefit from a free-er flowing exhaust, you'd have to modify the intake and re-map the ECU at the very least. This will only give you some positive results if such a *package* is properly engineered and it is very difficult to beat the factory with one.

I am not sure I understand this, Jim. But, the stock toe out spec is + 8' which is roughly 1 mm which is a hair under 1/16". This is somewhat aggressive but gives you very precise and quick steering with a little dartiness in straight line. Going to 1/16" toe in will increase straight line stability but reduce steering response. Can you please describe the before and after behavior of the car? Thanks!

Hi Jim, Where did you have the toe set at?
-
Porsche factory.

Ciao Andrea, I would be interested to hear more about the P-Zero Rosso tires on your car. Enjoy in good health, VB

What do you mean by different versions? There is one set of PCCB and another set of steel rotors. PCCB rotors: Front Left: 996.351.031.92 Front Right: 996.351.032.92 Rear Left: 996.352.031.02 Rear Right: 996.352.032.02

The front rotors are the same size at 350 mm but the rears are 20 mm smaller. From what I understand, the calipers are the same except for color. And, as you know, the yellow pads work on both PCCB and steel rotors. The only other thing that's different is the fluid feeding tube. I don't know what's different about it other than the fact that it has a different part number.

As you say, Craig. The tires have nothing to do with this. It is a typical function of a sports car and ldw gave you the best explanation as to what contributes to the feel. BTW, I was under the impression that the Rosso was going to be supplied as of 9/03 production. But, now I hear the factory has installed many of these on early production GT3's. However, they are all outside North America. My car is still on the ship to dock today or tomorrow. I am very curious to see what the tires are.
-
No, the GT3 wheels will not fit the Boxster. I am not sure about the front wheel but the rear one will surely not fit.

>> Welcome Viken...your knowledge and expertise is always appreciated! << Thanks for the welcome. But, what knowledge are you referring to? Compared to Loren, I know nothing. ;)

This is a cool site, guys. I didn't know it existed until now. :clapping:

It is my understanding that the new Michelin Pilot Sport 2 was under development when the 2003/2004 GT3 was conceived. This tire will be made in a variety of sizes and will eventually replace the existing Pilot Sport. At this time, however, it is only being installed on the GT3 and the Carrera GT. Will likely make its way on other Porsche models in the near future. As to the Pirelli, I don't know about a new Rosso but Porsche has tested the Corsa and the Corsa Asimmetrico on the GT3RS. I am not sure if it will be available as an OEM tire, however.
