Intrax suspension failure

[Thorney]

AH, missed that. Heard of the US ones but was told that was primarily earlier cars and a US issue only (or certainly not as common in Europe for some reason?). Not seen a failure of that kind here yet and we get a few ring, track cars here.

Read my reply again - I am refering to the rear diff subframe mount not the rear shock mount - 2 different weaknesses in the E46 chassis.

Apologies - I'll get my coat...........

Whilst its not right to say I told you so it does validate an opinion we have mentioned (and been criticised for) over an over again. Glad to hear he was OK. The chassis was not designed for a rear coil over, period.

We have designed this to address the issue should people not want to go for a full cage (the only alernative if you want to run rear coil overs)



You cant see from this picture but the brace/harness bar has a top plate that fits over the suspension tower and the suspension bolts to it directly. The lower portion bots directly to the chassis floor.

John, how much and does it need the boot carpet cut about?

Also, roughly how much labour (cost) to take the Intrax off and refit the std stuff?

Cheers...

[Thorney]

We can cut the bootlining so its in flaps so one removed they flap back into place.

About an hour to remove, 2 hours to fit new and 2 hours geo, so all up around £400 or so?

Does the KW Clubsport need the same thing?

John,
I'm sure you've looked into this, but bolting the suspension onto the brace/harness bar then assumes the harness bar top plate was designed to be fully load bearing with the car's weight+ in mind? Excuse me if I'm asking the bleeding obvious!

ps, any chance of those bolts you asked Adam to send over? :beer:

I'd be interested to know too.

[Thorney]

No, KW run seperate spring and strut on the back. Even the race suspension runs separate spring and strut.

Bleeding obvious.......but bleeding sensible.

Yes, the issue is that the chassis is not contructed to take the kind of stress that struts generate, so the bar is designed to strengthen both the supporting area (the top mount itself) via a 5mm thick steel plate that fits around the top of the mount. The suspension then bolts to this plate. However as well as this we use the same system as with cage design, ie you make sure that all areas of the chassis are supported along a minimum of two axixs. With the rear bar we tie in the boot floor to the suspesnion tower to ensure the tower 'shares' its stress along a wider area.

From the picture it looks like you can use this to connect harnesses to also

[Nords]

Cheers John, roger on the £400 to swap back to std. How much for the rear suspension 'strut brace' and how much to fit?

[Thorney]

Yep, that was the point. Create something with multi purpose.

We've got 5 in stock. Fitting is about 2 hours (plus harness, another hour say). The bars themselves are £670 complete kit.

Lordy, was planning to swap the Intrax off and get it serviced, see what std suspension is like and then decide whether to stay std and sell the Intrax or refit with that rear bar. I'm wary of the Intrax and the pressure put on the top mounts; that rear bar seems ideal.

Time to start saving I suppose! I have some Shroth (sp?) harnesses already but std CSL seats soooooo a bit arse really!

[Thorney]

We can put a deal together if you like. Issue is that stock CSL seats cant be used with harness's (no cut outs). But we've done a couple of deals:

rear harness/suspension support bar
Schroth harness
Recaro Profi SPG seat (single or pair)

£2k for one seat, £2800 for pair.

You'll get at least £2500 for the standard seats on ebay, we did.

This issue with the rear suspension failing the chassis is that whilst its repairable (and easy to hide, if you're that way inclined) it does mean the chassis warranty has gone.
