who, exactly?

 

'06 with F55 now at 13,000+ miles - no probs and noticable difference between Tour and Sport on any kind of road. The Sport really hunkers down for all aspects of performance, but is still not invasive for comfort. I will never have anything else!

 

The difference between tour and sport modes is not in the firmness of the ride per se. Sport mode emphasizes certain algorithms or calibration sets to 'tighten-up' the steering or handling of the car more than anything. Differences between the two modes can often be subtle.

Problems with the F55 seem to be extremely rare but problems can happen with anything mechanical. If you truly feel there's a problem with your F55 suspension, have the dealership check it out.

If you like, PM me you email address and I can send you a great article about the F55 system in the Corvette.

 

I can't believe how all you Z-51 option people feel the need to preach about it non stop. Why do you feel that saying "you should have ordered the same options as me" is usefull or constructive information. Go start a Z-51 mutual admiration society elsewhere on the forum please, and leave those of us choosing the next generation suspension system alone.

 

welcome to the vette world man....

 

Z51 = old school boy racer suspension on a street car. bouncing up and over the bumps. F55 is the future of suspension.
On our race cars, we needed triple adjustable shocks and several sets of springs to test with for each track we raced at. We tested all the combinations to find the "setup". All race teams do this constantly. Nascar teams carry a shock dyno in the transporter to tune many shock setups each weekend. A Z51 suspension is at best, a one track setup, that can't be tuned for the various tracks the car may be driven on. Most all racers know about mechanical grip, and how to stiff a spring and or shock will cause the car to nervious over bumps and lose grip. The true stiff suspensions in racing today are used to control ride height changes caused by the areo, ground effects, and the downforce the car produces.
F55 does adjust the damping rate 1000 time per second of each event (bump) that each wheel experiences. If it is doing what is is programmed to do, the mass of the sprung weight will be used to control the wheel reaction to a bump with the F55 decreasing and or increasing the bump and rebound of the damper in real time. It is trying to control the tire loading.The factory described it as a car on a skyhook, with constant load on the tires. As the engineers tune the algorithms that control the F55 it will only get better. If the F55 is doing its job, you will not have to notice the difference between tour and sport, but find a bumpy track or road, and it will perform.

 

Try the same exit ramp with it in both modes. Try one with a defined expansion joint. The car will hop less in sport, but you'll feel the bump more.
