IVA Fail advice please
SJC - 6/6/11 at 12:41 PM

Hi

Took car (Luego Velocity XT) to Gillingham for it first test, failed so now have a list.

I have tried using search facility but does not appear to be working like it used to???

Couple point i would like some advice on.

The adjustment of the top mushrooms to improve the self centering, i think i have the washers in the correct place on the wishbones but can not find where people put the top ball joint. Any advice would be great.

Also failed on handbrake compensation and efficicency, i am using powerlight handbrake calipers with the smart pads, i have read all different things about what pads to use to improve efficiency of the HB.

The copmpensation part, i used the rally design cable that goes throu the bottom of the handbrake and he faid it on 'Compensation device not of a suitable nature' Any pictures or advice on what other people have done would be great.

Finally on the manufacturers plate, just to check they require the chassis manufacture and model (Luego Velocity XT) then the chassis number, and then the total weight and axle weight. Are these the figures that went on the IVA form I.E 500kg 500kg then 1000kg?? Any advice of example would be great.

Many thanks for any advice pictures etc.

Regards
Stuart

Mushrooms should be @ 12 oclock looking fwd. Best of luck with the retest. Sorry but can't help with anything else, sounds like you did ok though.

not too bad

who was the tester Andy or Neil?

if it was me i would ditch the rear setup in favor of sierra or golf items willwood and highspec have always seem to have issues passing handbrake efficiency without faffing about, its a shame really as they are spot on for normal driving conditions.

if you have a problem with self - centering, you need to adjust the castor angle - as you say, the mushroom is the only way you can adjust this without altering the welding of the suspension brackets is to turn the mushroom. the mounting hole is off - centre, so as you rotate it, it will tilt the castor angle, to improve the self - centreing, you need to have the pivitol axis (around which the wheel turns when you steer) to tilt further back. One other cause - the upper wishbones have one arm very slightly longer than the other, and if you have fitted them incorrectly, this will also affect the self - centering

[color=Blue]In the velocity build manual, there is an instruction about how to provide compensation -

This is exactly how I did mine though I did snap one cable off when I arrived at the test centre! (1 of 12 fail points)

We could do with a photo of your set up to see if we can help you with your layout.[/color]

Finally on the manufacturers plate, just to check they require the chassis manufacture and model (Luego Velocity XT) then the chassis number, and then the total weight and axle weight. Are these the figures that went on the IVA form I.E 500kg 500kg then 1000kg?? Any advice of example would be great.

your plate needs the manufacturer (Luego) name and the VIN stamped on it. You do not need to put the design weights on the car at all. (Design weights for mine were 550Front 500 rear 1050 total - they are only needed on the application form. Have you stamped the VIN under the bonnet on the RHS? - I failed because I stamped mine under the nosecone.

There are a couple of other tricks to try as well, pump front tyres up to 30psi, dial in a bit of toe out, not how you want to drive the car in anger but will give the desired effect for IVA.

heres a pic of my chassis plate (its a sticker)



edit: Of course I also have a plate welded on the chassis with the number stamped on.

Yeah but to be fair they only supplied the chassis and body. Got through IVA with it.

Thans for your replies,

I had Andy testing the car.

Going to swap back to the original hanbrake lever and fit the compensator that is on that.

Re test booked for the 24th so fingers crossed....

Cheers
Stuart
