New tires usually come with mold release agent that makes them feel slippery. Give them a few miles and also check your tire pressures. They may have set them too high if the car feels loose at highway speeds.
I'll agree with you that most people wont notice on everyday driving but when it matters most is when tire choice becomes important. Like having to perform an evasive maneuver because a vehicle lost control in front of you or wildlife crossed the road and your tires are not in sync with each...
Most of the the tire wear occurs when you're breaking the coefficient of friction of the tire against the road, during coasting you have rolling resistance and the forces acting on the tire are lower than the forces needed to accelerate a car or stop it.
The weight of the car and alignment...
On AWD, depending on the bias of the car, the fronts have three jobs, pull the car in acceleration, steer the car and do most of the braking so they tend to wear quicker or at a similar rate as the rear. On RWD cars tires usually work harder as it has to push the car at all times.
This I would advise against to most people unless youre specifically trying to induce a certain type of behavior from your car that you couldn't achieve via suspension settings, aero or weight balance changes.
When tires are mismatched they can cause that axle to behave differently the other...
Depends on how you look at it but if you have the 21" PZero, the front already have larger rolling diameter than the rear.
I really doubt Porsche took this into account on their tire selections between available 19" 20" and 21" so there's already variable difference in rolling diameters...
Same here, I used to think my tuned 750i drove 'sporty' for such a big heavy car with a long wheelbase. Now it feels like an 80's Cadillac in comparison and I dont even have PAR.
From the pics it doesnt look deep at all only cosmetic, these calipers have a lot of material to help with heat dissipation. Looks like some road debris got flung inside the wheel while driving since it follows the direction of rotation.
As someone else noted check the wheel as well and see how...
He didnt use lowering springs. He either used lowering links to trick the ECU into thinking the air suspension is higher than it actually is or recoded to the ECU to do the same.
There was an extra allocation.
Everything has been ordered, we are now at the mercy of the machinist and the shop doing the anodizing.
They should be shipping out in 3-4 weeks. thank you all for your patience.
I will agree on Rear wheel steering as it makes the car feel smaller and more responsive. I have driven an active drive but it also had RWS and I didnt get much (usable) seat time on one to appreciate it. But if i had to choose between both of them I would opt for RWS over AR.
The Kuat can bolt up to the bars but new additional hardware will be required. The hardware provided by Kuat is not compatible with the hardware I provide since Kuat uses metric hardware and I provide SAE to work in conjunction with the 1up Rack.
