benchmark when getting a KDS set-up at a BMW
 

"Front Axle

Castor (left/right) = +7 deg 13 mins /+7 deg 12 mins
Toe out on turns (left/right) = -1 deg 48mins / -1 deg 58mins
Camber (left/right) = -1 deg 57mins / -1 deg 53mins
Toe (left/right/total) = +0 deg 01mins / +0 deg 01mins / +0 deg 02mins

Rear Axle

Camber (left/right) = -0 deg 52mins / -0 deg 49mins
Toe (left/right/total) = +0 deg 02mins / +0 deg 04mins / +0 deg 06mins
Geometric Driving Axis = +0 deg 01mins

Remember, -1 deg 60 min is the same as -2 degrees"

"BMW dealers will only be able to achieve up to -2 degrees, more likely -1.75 degrees since they will not (for obvious warranty reasons) rotate the strut or remove the locating pin. With the locating pin removed you can get nearer -2.5 degrees with the OEM strut. Also rear toe will make quite a difference to agility into corners.

But remember the greater the camber the less directionally stable the car will be. Not a problem on track or on smoother roads, but more effort on bumpy cambered b-roads. -2 degrees is perfectly comfortable if you like to feel the road through the steering wheel"

:thumbs:

Are these the OEM settings?

They look like the settings SteveD posted on Mtorque...

While on the subject of 4 Wheel alignment and KDS, will have to do it again after changing the rear top mounts? Certainly hope not as the parts are cheap enough and I'd be replacing them myself!

Would've thought so.

If you're just changing the REAR top mounts then you will NOT need to realign your car, they have no bearing on your suspension geometry.

Thank you BM sport, thats the news I was wanting to hear. Get them done next weekend, mine seem to squeaking alot going over Speed Bumps. :bigcry:

fair enough, useful to know, cheers.

Factory target spec is below:

Front Axle:

Castor +7deg 40 (+/- 30mins)
Toe out on turns -1deg 32 (+/- 30mins)
Camber - 1deg (+/- 20mins)
Toe +0deg 08 (+/- 04mins) total toe +0deg 16

Rear Axle:

Camber -1deg 45 (+/- 15mins)
Toe +0deg 11 (+/- 03mins) Total +0deg 22
Geometric driving axis +0deg 00 (+/- 04mins)
