::.. Wheel hop. Hipity hop...
Under dry conditions, I'll get rear wheelspin signalled by very minor chirping. In wet, any launch above mild will induce wonderful chassis-shuddering wheel hop.
My question then is: I take it this is not normal? That is, no matter dry and wet, the power should stay down and wheelspin instead of hop?
By the way, I'm riding 235-45/17 with Vogtland Sports on Bilstein HDs. I'll switch over to the Koni adjustables once the Bilsteins die.
On a side note, I'd guess that hop is better than losing the rear in a spin. Of course, your drivetrain starts to hate you then...
---------------------------------
Wheel Hop:
Definition: An undesirable suspension characteristic in which a wheel (or several) moves up and down so violently that it actually leaves the ground. Wheel hop can be caused by many problems, including excessive unsprung weight, insufficient shock damping, or poor torsional axle control.

- Subframe bushes? CV? Guibo?
- ... centre drive shaft bearing. If the rubber around the centre bearing housing has failed, the driveshaft will distort under acceleration and the shaft bangs on the support surround.

- thicker sidewall tire with less pressure such as the stock 15's
- stiffer rear swaybar in a traditional type car
- different compound tires
- shocks may be too stiff along with stiffer springs all contribute to the hop

- Wow. Apparently the Cadillac CTS-V has major problems with wheelhop

- entire suspension (control arm or solid axle) starts oscillating
- RWD, wheel hop is strictly related to tire & suspension design and the surface you are running on
