Getting the WIM treatment
« on: 22 September 2008, 10:48:56 »

The mig's up on the ramp getting the treatment as I post this! These boys know what they're talking about! Had to get a bit of heat on the rear adjusters but it's getting there! Well worth the trip IMHO!

Incidentally... Who else is coming today? Got 4 booked in today!

Now that was well worth the visit... The car is transformed! Needed a bit of heat used to free things off but it really has made a difference! The turn in is noticeably improved!

Just got to get 2 new tyres to replace the barely legal crap on the back wheels... Move them to the front to try and even the wear on the current ones and it'll be finished!

A big thanks to Tony for taking the time to explain the machine and what he was doing for me too :y :y :y

Well, its done. Feels alot better,new tires "but"... something else is a bit vague i think. I will compare
on the journey to work on roads i know but i have a feeling it now pulls a bit to the right even on a slight camber, i was expecting it to be set to run straight on a flat road, they may have set it to run straight  on the a slight camber as thats what your likely to be on mostly. Ill see how it feels in the morning.
By the way, they mentioned something about the caster not being quite right and the left front camber being more than (out of) spec. to compensate. Seemed logical as the left front
was worn on the outside, roundabout, edge. But i would have prefered the front subframe positioned to give the correct caster angle to start with and then set the rest from there.

A trip to and from work will confirm how it feels. Ttfn.

Chris... I'd imagine they reset everything for you... They did with mine! Tony's very good though... If you're still not completely happy I'm sure he'll have another look for you :y :y

I'm sure I remember him saying at the open day that caster was not adjustable, although in hindsight I thought the front subframe was..   :-/

Not directly adjustable, but other adjustments have an effect on it...

Yes so do i, and officially it is not( oh listen to me im doing it again, taking other peoples second or third hand info and making it sound factual) i should say i was told by another set up firm, and i did witness him do it and note the readings, "that the subframe holes have such play in them that the caster can be miles out as vx just windy gun the bolts up any old how at the factory". He then asked me if the stearing was slow to return to centre when pulling out of a junction, it was, he adjusted the subframe and it was much better. He also said, even vx dont know about that one! The car was transformed, but considering the right front was rubbing on the shock, it would be.

I wonder why, in wims own words iirc, the caster is not quite correct, given that it is not(officially) adjustable? Anyone? Could it be that the subframe is not quite in the correct place?

Now before we all go casting doubt on all other set up firms i have used this company several times and  various cars with v good results but they have become too big and impersonal.

@chrisgixer
Unfortunetly i was in a meeting while your car was being calibrated.... If you can pm me the registration number i will check the report for workmanship.

Historically if the OSF castor is below spec we ignore this within reason because the low castor belays the push effect of the road crown a reduces the cars tendency to drift left.

Castor stagger is quite common, in fact most German calibration positions have this set into the target area.

Displacing the sub-frame is also used on some cars to "optimize" calibration positions, this may be where you garage got the idea?

This method is only used for camber optimization "not castor".... The reason for this is the position of the inner wheels accentuated lock is controlled by the transverse symmetry of the cross-member and the steering arms... Displace this then on one lock the steer position will not return fluidly and the other lock is rapid.

I would like to look at the report but fundamentally if your not happy please return to us and i will measure the chassis.

I hope this helps
Regards

Hey Tony,

I was down WIM last week, your guys did a great job  :y

I forgot to ask your guys to balance the wheels (i did not get new tyres btw)

I get vibration through my seat at 80+, i think the rears are not balanced right.

Can i pop down at the weekend just for wheel balancing?


Sorry to hi-jack this thread btw!

Hmmm, not sure about it tbh, the set up i mean. Having been to work and back, its a whole lot better dont get of wrong, but it drifts to the right, it difficult because the camber pulls the stearing wheel, as it does. On some occassions ridding up a slight  right to left camber.
  But i am sure somethings not right at the back, unrulated to the set up, it was there before that and the new rear shocks and set of tires. I had hoped any of those changes would have got rid of the symptoms but its still there, wim spotted a broken spring at the back drivers side but only an inch at the base. They dont think
It will affect anything and i dont think that would cause the loose back end feel off the throttle, like its got a puncture/2 low pressure rear tires. Or a cut and shut with a dodgy welding job. Anyone know about rear suspension bushes? Ill give Tony a ring in the morning and i suppose i should change the rear springs. Can i just fit mv6 springs(all round) to stock dampers ? No, didnt think so. Cheers all.
