When you drop the clutch and move off at a fast pace do you ever get a banging noise and the who car feels like it's going to hammer it's way into the ground?

EDIT: It happens when the wheels break traction with the road.

Is it different to wheelspin then?

Definition:

The suspension and engine are connected to the rest of the car with flexible, rubber bushings and mounts. This flex kills vibrations, but it also produces a secondary, unwanted, oscillatory mechanical system. Normally, this system isn't acted on in such a way that it oscillates. When launching, the weight transfers to the rear of the car, reducing traction in the front. As the front tires break traction, the forces on the suspension and engine also change, setting them into motion. When the tires grab again, the forces change back the other way, now applied to a system already in motion. Now we have an oscillating force applied to an oscillating system, much like a hitting a paddleball. If you apply force to the paddle to match the natural frequency of the ball attached to the elastic string, you can keep that system going all day. With wheel hop, the motion of the system feeds back to the wheels, causing the oscillating force to sync up with it. This will also go on all day

This is a defintion I found via the web, as it say, wheel hop is an effect of wheel spin.

We used to call it tramping in my old rally days [;)]

Its wheelspin but with the wheel hopping up and down...

Memories of Mk2s with cheap shockers.......

Doesn't happen these days with 50mm Ohlins[:D]

Yes i know what it is. I'm always flipping getting it in my 180!

I even try and not to accelerate too much in 1st now but sem to get it too easy in the wet!

TOO MUCH POWER!

Shouldn't VW have tested this out before upping the power to 180hp if its so damaging?

hmmm, I get this a lot, am I right in thinking better shocks and springs (more accurately FK coilovers) will aleviante this problem?

When did we start calling it "wheelhop" ?? Surely "Axle Tramp" is the correct term

Risking the chance of being ridiculed against all you guys with turbos and V6 engines, but i get this as well in my 2.0. The roundabout close to the house is slightly on an upward slope on approach. So setting off gets the wheels going (if i don't accelerate really slowly and i mean slow - like a wheelspin but going up and down as well (for want of a better description) - happens fairly frequently now i think about it.

I've obviosuly got no ASR or anything like that and I had assumed this was the reason.

WSL_WIL, forgot to say, yeah, this is what's it's like on my car - when i starts, your going nowhere until i take my foot off the accelerator until it grips - it's a lot more exaggerated than a wheelspin. I mean a wheelspin eventually grips but this doesn't.

Funnily enough ive noticed this in mine on an uphill slope roundabout. Seems to happen everytime but nowhere else apart from the roundabout.

Gets me a lot when i coming into work at the same roundabout. Setting off, going left, it does the jumping around if i'm not careful.

If that's enough, coming home, at the same roundabout, going right around to the right now, the car slides, like it's losing grip and sort of 'jumps' a little - i think they need to resurface it. Pain in the ass it is.

Everytime i go round this place with someone in the car they keep saying stuff like 'where's the fire' and 'who you racing'.....

I mean, I know the 2.0 isn't as fast as you guy's but it does feel suprisingly 'torquey' when it's setting off (up to about 20[:I]).

I dunno if the 1.8t has the same suspension as the 2.0 (probably better on the yours I would think) - maybe it's just the weight distribution of the MKiv car as whole rather than model specific?
