Believe it or not, this morning was my first experience in the S driving in wet conditions. While I was at rest behind red lights, I decided to check the traction on wet roads. I revved to 4K rpm and smoothly depressed the clutch. As soon as the rear wheels lost traction the car vigorously vibrated vertically and the gear lever horizontally. I tried this again on another set of lights and the same. The vibration feeling was like having the wheels deformed in an oval shape.

Is this normal ???

 

That's wheel hop. It happens when the drive tires are getting traction and losing traction at a certain frequency. It causes the suspensino to "hop". It happens a lot more with FWD cars since the drive wheels get unloaded on acceleration. Still happens to RWD cars too.

Either speed up to cleanly spin the tires or slow down to allow the tires to get full traction, or just ride it out until you get going.

 

lol when I saw the topic and description I thought this was about something else...

 

So i know that this isn't any fault concerning the suspensions or mybe wheel goemetry. I will try to push it harder next time and see the results.

thanks

 

a perversion to be listened. (marketing)

 

I hope by "push it harder" you don't mean you're gonna rev it higher and do the same thing. No offense but it sounds like you're experimenting with RWD in the rain and using your S as your test subject. It's been proven time and time again that that is a recipe for disaster. If you want to learn how to drive the car in the rain do it in a big empty parking lot so you don't end up connected to a tree or lightpost.

 

I will "play safe" with the car. my concern is to get my mind at rest. I have other tiny faults i want to get sorted(if they are actually faults) before my warranty expires. All my past driving skills are coming from 200+Bhp FWD car, I had the same problem and resulted to be just as desc above. RWD cars tend to sink down the driving wheels unlike FWD which lacks traction on accelerating.

Thanks for the advice.

 

 

Thought the same thing! lol
