What is scuttle shake ?

Sorry for asking such a dumb question but can one define this to me what it means by giving a little more explaination ?

( having never driven a cabriolet )

it is where the car flexes under heavy breaking. it happens because the car has less rigidity than normal cars as the roof is not joined to the car.
i think ...

Anyone worried about braking in the CC ?

I've had a couple of close shaves and am concerned at the cars stopping ability (ESPECIALLY at speed). Driving back from Robbies yesterday was an interesting experience ! It wasn't only the car that was 'scuttle-shaking'

I have no concerns with braking. I had my CC out on the racetrack a few months back doing an advanced course. We were told to accelerate to 100 kph (about 60 mph) and stop as quickly as possible. The road surface was covered in water. On one pass I was told by the instructor that my stop was one of the best he'd ever seen at that speed.

Braking is very much about technique. Technique with ABS is very different to vehicles without ABS.

Furthermore, in the cornerisng exercises we did a tight slalem and I have to say the CC performed beautifully.

All in all I think the car handles very well. If you aren't happy with the way it drives you should perhaps take a look at your driving techniques, or invest a little cash to get some professional driving coaching. Some of the best money I've ever spent.

Indeed Frostly, everyone should check this site out: http://www.roada.org.uk .

Please feel free to correct me if Iâ€™m wrong but I was under the impression that Scuttle shake in the 206cc was actually less than the normal 206 when the roof is up !. I know that there is the join at the front but the reinforced A pillars actually compensate adequately for this. Admittedly there is scuttle shake with the roof down but Iâ€™ve never found it excessive. With the low profiles of the tyres any imperfections in the road (basically any road in the UK then !) will give you less than a perfectly smooth ride.

Hi there

The best explanation I have seen of scuttle was on Top gear.

They compared a car to a shoe box. A shoe box with a lid on makes shoe box very solid, it does not flex at all or very much, but if you remove the lid, the box will flex in many directions.

A soft top looses it rigidity because it has no roof, like the shoe box without the top on. When you drive a convertable as the car hits bumps in the road the car flex's and this can be usually seen and felt through the movement in the windscreen/pillars. Look at the vibritions in the rear view mirror.

I agree Rich...i've never noticed much 'scuttle-shake' at all. In fact i was extremely pleasantly surprised with the CC, when compared to my only previous convertible driving experiance (an Escort XR3i Cabriolet) which had more shake than Elvis' hips! :razz:

can one feel this in the steering wheel when breaking hard or driving on a bad road ? I remember the Â´driven Â´review with the pudding. Was that caused by scuttle shake ?

Think it was caused more by the cobbled street if my memory serves me correct!. Best bet is to go for a test drive. Think you will discover that scuttle shake isnt that big a problem.

Yeh Driven ugggh!

Who in their right mind would test for scuttle shake using a badly setting Jelly on cobbled streets.

I mean, how objective a test can that really be?

Well I think it's a very relevant test because I carry a jelly in my car over a cobbled street at least once or twice a day and it's not pretty...

Now where is that sarcasm smiley...

i think the CC handles very well and ABS makes it far better than my old LX.
