Scuttle shake - can it be reduced?

[PeteE30Tourer]

I never really understood what scuttle shake was until I drove the cab home after buying it on Saturday. I was quite alarmed at how much the screen shakes from side to side. Could also explain why the dash is split in several places across the top. With the hood down, it's even worse.

Would a strut brace help this? Any other ways to calm it down, or is it just life with a cab?

[DaveD]

The first thing to do is to check the rear bushes ..then the rest of the suspension...a well set up cab should not shake that much

[mrLEE30]

with dave on this one, even with spirited driving my cab window does not shake from side to side. having the roof up will make no difference structurally.

3rd that, mine never shook, never felt it tbh even with doing 140 on a private road . Check and replace worn out bushes, will help the drive a lot

It was 'chipped' innit

Oh and also, the fitting of a front strut brace will help

[PeteE30Tourer]

Thanks for the replies folks. The ride is a bit trashy at the moment i have to admit, so the bushes seem a good place to start. I can see the £££ rising on this car already!!

[toby]

Convertibles never felt as rigid, even when they were brand new so don't expect to eliminate it altogether. I'd agree on the bushes and start with the big ones first - engine mounts, rear beam etc.

Do you still have your touring? I thought you had it up for sale a few years ago.

Thanks Toby. The Tourer was sold about 5 years ago. Must change my sig pic!

Those leather fairies look nice - might have to take one of those of you!

So cynical.....

I'd go for OEM bushes as well

he had big rimz so da speedo read incorrectly innit, was actually 95mph

[PeteE30Tourer]

So how much for an OEM set of bushes all round roughly?

depends if your fitting them yourself and what bushes need replacing. get it in the air and have a look it possible

cost me £250 for two front wisbone bushes fitted and both rear subframe bushes replaced by a bmw specialist i supplied m3 offset bushes for the front.

[ImysE30]

Bush renovation list below, prices will most likely be out of date:

I'd try and get it up in the air first and then see what actually needs replacing.

Oh and Alex, that was when i had 16"'s on

No.

How is that cynical? I think most sane people on here would agree that you have never achieved 140mph in a 'chipped' 320i.....

I'm going to give you an out here and say you meant 140km/h, right?

[ImysE30]

I would do it again just to prove you wrong but the i have a m30 now

Never happened.

Maybe it had an M42.

[mrLEE30]

i can only just see 140 mph in an X6M down the main straight of our GP circuit before tuirn one looms close, and its almost 2 miles long, the X6M is only one of two cars i have ever seen that speed in, the other being a GT3. the 400hp Holdens only manage 130.

I would challenge any standard E30 to reach 140mph, in fact i would wager a large amount that ANY E30 could not reach 140mph without a 5 mile straight and a following wind

i would like to know how long and where this private road is, as i suspect many people will be interested such as top gear, and a million car magazines.

[Ian_M]

You won't be reaching 140 with that either.

[e30topless]

I would challenge any standard E30 to reach 140mph,

it's been done in a 325i many times, a B20 tops out at aroud 125

i would like to know how long and where this private road is,

I would assume it had 3 lanes and spans the country !

[b17]

I would challenge any standard E30 to reach 140mph,

Mine's powered by crystolafusion imploders and will do this in reverse

Genuine l0l

[ImysE30]

I assume you mean standard E30's Mr Lee? I've driven a 2.5 and reached 140 easily

I'm sure M30/M50/M52/S50 etc powered E30 can reach 140

140 on a speedo is alot different to an actual 140 and i thought your B20 was easly up to 140

[ImysE30]

Who said anything about it being easy

[Dezzy]

Who said anything about it being easy

Easy or not it NEVER happened and you know it

[Ian_M]

A stardard 2.5 will really struggle to reach 140mph, any guru out there have the figures? 140 on the speedo, as Dezzy said, is not actually 140.

Also, convertible top speeds are lower so you'd have an ever tougher time getting to that point.

Not true.

Depends on what engine you have in the bay.

Steve (E30Topless) will back this up, we both were travelling in excess of 140mph a few months back.

I'm no expert but a quick bit of research to look at standard 325 stats, the convertibles top speed is lower.

All of this 'but I've seen it and so has he' is hardly proof, especially using a speedo.

Me and a mate watched me recently get 170 out of my bog standard CTR... You can't dispute that.. because I said so.

Finally, a quick look puts the 325 standard (non convertible) top speed at 136 mph?

Was this on the same magical road that Imy was on with his B20?
