How much do you want for the strut brace, and will it fit my Foreser?

Many thanks to Iain & Tim @ Litchfields

How much for all above

[Robocop]

Make me a sensible offer. I've got a figure in mind, but let's see how far you're off.

Where are you based btw?

Me sensible, come on.

I haven't a clue for second hand value, you give me an idea of cost and i will decide if i think it's worth it.

i'd be interested to know how much difference the strut brace makes ?
was thinking the other day that the car was leaning quite a lots through corners...

[danr55]

p.s congrats on the sale, that was quick.
now what's next ?

It won't stop the car learning, but it did firm up my steering. I def noticed a difference going round a roundabout.

Here's a cut and paste Q&A with Damian Harty, Prodrive suspension guru.

Strutbrace Q: There is an awful lot of mythology around this stuff that goes back to body-on-chassis beam-axled racers in the 20s - I'm not kidding. There are two effects that are important. Basically, the body structure is like a "fifth spring" between the front and rear suspension. If that spring is not stiff enough then the body relaxes out any redictribution of roll moment that the anti-roll bars were trying to make and so the car is unresponsive to handling balance tuning with springs and bars. However, once the body is "stiff enough" then making it stiffer offers no benefits. A good rule of thumb is that the torsional stiffness of the body (between suspension mount points) needs to be about ten times the roll stiffness of the stiffest suspension end (usually the front). If you chase the numbers through you end up with about 5-7 kNn/degree as the requirement for a body structure. Most modern monocoques comfortably exceed that and the Subaru with its bonded screens both ends does too. Somewhere I have a figure but can't recall it right now. Anything over 10 is good, 15-17 is current "state-of-the-art". So in that case, a strut brace does very little. The second effect is a bit more complicated. The body moves on the suspension but the wheel also moves on the tyre - the tyre is in many ways a "secondary" suspension system. That movement is partially controlled by the tyre and partially by the suspension damper and happens 10 to 15 times a second. The body is a flexible thing that has its own resonances and because of the shape of most cars at the front - they need a hole to put the engine in - it can get quite flexible in just about this frequency region. If the body goes flexible - goes into resonance - then the damper just moves with the body and can't contribute to the control of the tyre and in fact can do something bad called "mass loading" where the tyre is carrying not only itself but also part of the body _while it resonates_ (it's important to separate the static 'weight carrying' from dynamic things in your mind). In those cases, the strut brace can help because if it is a good design then it stiffens the front end usefully.

What all of the above means is that the effectiveness of a strut brace is strongly connected to the stiffness of your suspension. So for a Scoob that is fairly standard, the strut brace probably doesn't do a great deal, but as they get modified and stiffened the brace will contribute more to a well controlled feel over less-than-perfect surfaces.

This

spec ?

[Robocop]

Spec C with a Milltek exhaust K&N filter and 3 port boost solenoid. Half way to a T20.

2l or 2.5 ? what sort of figures does it kick out ?

interesting...
I'd love to know what effect it would have on the wr1, will post a separate thread....

[Robocop]

2.0l engine. It should be around 350ish bhp

[WR1 Bro]

I went for a blat in Ian Litchfields black Spec C. It was awesome. I think that was 360bhp.

[danr55]

i'll be down your neck of the woods for a go once it's run in then!

[Robocop]

Yup, I test drove the same car. Spec C Type 20. He sold it for about

[chris]

This

spec ?

You should reject that.

Some b*stard's drawn all over the windscreen and stolen the number plates.

Hi
Hopefully have it all sorted within a week.
Can you let me know about the Prodrive bits, as there is another interested party in some of the bits. No problem with ANC etc.

If I have no sale come the end of today, I'll be placing them on ebay along with a XDA2s PDA mobile.
Obviously I need to free up as much cash as possible now.
Regards
Kevin

I will take the lot

[Robocop]

No, it's a bit to far from me.
Let me know how you wish to go about it.

Kevin send me PM with your address and i will get a cheque in the post tomorrow.

Will you have a business address for collection once the cheque has cleared, let me know Kev.
