Had the new springs and shocks fitted and all tracked and cambered up nice for now. But just getting a knock when turnning right at speed say going round a roundabout. Seems fine on left turns. The knock does seem speed related any tips as here to look.
Car feels a LOT better with them now ...almost like a go cart... that,s 2 tons ;D ;D
Thanks
Steve.

should also add that the knock seems to be coming from the drivers side wheel :y

If no knock before the work, wondering if everything is done up properly?
What parts did you go for? genuine? just out of interest...
-
Hi Chris good point will have a good check of that, seemed fine but you never know. Have the irmy springs and shock from Vader only fitted to Vader in Jan so like new.
it,s lowed the car by about 30mm which i like and the ride is just fine. The handling is much much better.Looking forward to taking it for a good run soon
-
Droplink?

Droplink?
possibly, if the car was not in a bend then yes definately. But usually if the car is cranked over all the play is taken up with tortion bar being pushed up by the opposite wheel. Only when the car is level do they rattle. But worth a check.
-
Rear shock absorber mounting bolts have been known to work loose after a few miles following installation as everything settles...
At the front, drop link might be a possibility?
Worth a general bolt check front and back in case something is loose.

Thanks for help everyone , had a good look over things and turned out to be a wheel weight that was on the inside of the rim insted of the center of it. As the wheel was in a right turn it was just knocking against the shock tower. Removed and all is fine :y :y.
Have a few pics of the car with the new shocks and springs fitted will post up later today.
-
you did say speed related, didnt pick up enough on that,
strange though, shouldnt be that close with stock wheels, or are the shock bodys a wider diameter? or there is too much camber set.
Gap between stock 235 45 17 wheel rim and stock shock on mine is about 15mill with camber set to 1.10, more than enough for a wheel weight, assuming the wheel weight is fitted correctly of course?
-
Good point still have to run it to WIM or Fleetfit to get it done spot on ;) ;). The Wheelweight was not fitted very well half on half off....but then again it was done by some place that had no clue what they where doing. New place used the stick on one on the inside of the rims. Not sure about the diamater of these ones..will have to check them to the old ones and see.
Had a run over to Cov and back... the new set up made the trip fun ;D ;D ;).Far better handling now :y
-
I think we have got to the bottom of this.
The person who fitted the shocks had made a few errors
1) Having effectively lowered the car, they had not reset the front wishbone bush......this is now done. (let this be a note to all who lower thier car...!)
2) The spring retaining nuts on both shocks were loose with the NSF one being very loose
3) The person who fitted the shocks in a moment of desperation had placed some rubber between the top plate and the strutt.....this had resulted in the NSF becoming very loose
Sadly, nylocs had been used and the one on the NSF had been tightened to a stupid level as part of the rubber bodge.....so it had to be cut with a 1mm cutting disc to remove it.
All sorted we hope and Steve I am sure will update once he returns home.
-
;) ;) Now driving like a dream :y :y. So Good took the very long way home from Marks :y :y

I still rate the Bilstein B4's plus irmscher springs as the best all purpose setup for the Omega

It Is just the best. You can have a very good ride with about the same feel as the MV6 set up on a normal road ...but take aroundabount on the inside at **mph and just power out with very little roll or fuss. And with just a 30mm drop looks just right.
-
Steve has just visited again due to a rubbing noise.....all sorted and a different piece of incompitence to the last piece of incompitence from a paid 'professional'
Anybody wish to guess as to what the fault was.....heres some background:
1) Springs and shocks changed by a 'professional' for Bilstein B4's with Irmscher springs
2) Full geometry done
3) Top mounts on strutts found to be loose and the wrong nuts fitted....fixed and knock cured
Still a rubbing noice though....so come on guesses please
-
.....
Still a rubbing noice though....so come on guesses please
Tyre rubbing on the inner wheel arch lining ... or ist that too obvious?
Top mount/bearing/bush at the top of the spring incorrectly fitted ...... or missing? :-/ ::)

Neither, good effort though.
The strutts were originaly assembled by myself and LooKnee so we know all the mounts etc are in place and fine
-
The clue is in:
'incompitence from a paid professional'
and the jobs done
-
If car now sits lower would the camber now be more advanced? I know it's supposed to have had a Geo but bearing in mind that they didn't release the tension on wishbone bush and reset it........

Geo was done after the spirngs were fitted.....but your on the right track
-
Tracking outwards either side?
-
Tracking outwards either side?
No, the camber is the right track....
The camber was so negative that as the tyre warmed it expanded just enough to touch the strutt!
The gap was very small when cold between the the tyre and strutt.
Note, this camber setup was 'in the green'
-
Excessive wheel bearing play?

'green', we know, isn't good enough.
Mind you, must have been right on the limit of green to heat tyre that much :o
-
They where very close to the struts...with the psi at about 32 and 15 minutes of driving it was all it tock
The set up was done at Tyres Galore in Leicester....will not be going back there >:( >:(.....Will be booking it into Fleetfit as of Monday :y
-
Must admit, that the tyres do seem very close to the strut on my Elite but didn't know if it was because of the angle when looking at them on full lock.
Also wondered if the Dunlops which have rim protection made the construction slightly more 'bulbous'?

rim protection only on outside, not inside?
-
Thought the Dunlops (9090 / Sport Max) were directional so can only be fitted one way regardless of side?

Directional and sided iirc.

Ah! I only ever buy tyres in pairs so I guess that makes it easy for whoever I buy them from.

Easy way to tell is if they have 'outer' written on the wall.

:-[ Yes they do....... LOL

you did say speed related, didnt pick up enough on that,
strange though, shouldnt be that close with stock wheels, or are the shock bodys a wider diameter? or there is too much camber set.
Gap between stock 235 45 17 wheel rim and stock shock on mine is about 15mill with camber set to 1.10, more than enough for a wheel weight, assuming the wheel weight is fitted correctly of course?

Hob nobs for me then? :y

Yes will be sent recored delivery 1st thing :y ;D ;D

Had a look today when in the car and found the data from the place that did the the set up and found they had the camber at -1.50 if that makes sence...would that get the big lean in a the top making it rub the struts.

Its too much, but surprised it caused that much heat on tyre.
When we did my shocks at Newent, handling aside, I had no issues doing 70 miles home in a semi spirited fashion ::), and they were wrong side of 2 degrees :o

no, doesn't sound enough to me, either measured wrong, wrong sheet for that set up, or do you have non standard wheels or tyre sizes?
i'm under my car now so if you need anything measured....

It was WAY more than that!

Were the bolts lose?

It did seem the kind of camber you would see on a lowered Saxo. Very bad.

No, F tight!
