Geo session - 2.1degree neg camber?!

bryce · 17-12-2008, 08:10 PM

Cars just been in for geometry.

Camber
On the front I wanted:

1.5 – 2.0 Degrees Negative

What I got:

Left: 2degree 10' Neg
Right: 1degree 42' Neg

They said they couldnt adjust it cos I dont have something. Might have been top mounts maybe. Ive got KW v3s.

Is this within acceptable limits? KDS printout says -/+ 0.45', but I think that's for a standard CSL.

Is handling gonna be to pot for the road and chew hell outta the tyres?

Hi

i am -2.18 on the Left and -2.20 on the right.

No problem for road use, a little more directive after 250 km/h.

id say half a degree diference is too much, but dont know how to sort!

Something's not right ... I think the left hand side top shock mount may have been rotated incorrectly to give that sort of difference - check the arrows and see if it's pointing in the right direction (i.e. when they were fitting the KWs they rotated the top mount incorrectly - you can get 3 different type of camber readings by rotating the top mount, largest is circa -3 degrees and the other around the -2 degree mark - stock standard it should be around -1.5)

Or they forgot to install the locator pin back ... see here: http://m3.madrussian.net/diy_camber.shtml

The only other possibility is you have a bent top shock mount (common) given they are alloy.

I'd check all of the above.

I fitted them myself, and as far as i could see there's only one way to put the top mount back on as there is a locating pin.

How is there different ways to put the top mount back in?

Thank you.

Possibly a bent top mount then or a worn top mount bush ...

over half a degree difference is too much ... the factory spec tolerance is +/- 0.2

You could always take the locator pin out and push the top mount outwards on the left hand side to give it more positive camber and more in line with the specs.

bryce · 18-12-2008, 12:04 AM

Factory tolerance I have is +/-0.45

Just checking them links just now.

Not according to the print out I have in front of me ...

I've got mine set up at -1.5 and -1.48 and that's considered pretty good.

Just read up on the madrussian link, and I see the pin is removeable so you can change camber. Ive not done this btw.

BUT

I managed to mishape the locating hole where the factory pin comes through. Circled in this pic.

Is this probably the cause?

Whats the solution?
