Default camber/caster adjustments

hello everybody,

If you change the caster on a 964 does tis change the camber as well(I think it does, as far as I can see)? Is it possible when you change your caster to use the excentric bolt to put your wheels further inside the wheel arch?

thanks

Maarten

Nope

Well all the alignment adjustments are relitive.

Caster is how forward or back the wheel is.
Camber is the vertical angle of the wheel 0 is standing straight up.

So if you are asking, if I put wider tires on the car and need to adjust the camber to stuff them under the wheel arch then yes, but it's a camber adjustment not a caster adjustment. However, excessive camber just wears out the insides of the tires.

My caster is like situation 1 in the picture at the moment, If its possible to adjust it like in situation 2 the wheel will be further in the wheel arch and the caster would stay the same. Then you would need to adjust the camber to put the wheel straight again?



What is the max camber jou can adjust in the front on a 964?

Caster is not going to move the wheel in or out. Caster is how foward the wheel is in relation to the top of the strut.

What are you doing and what are your specs?

Max caster is 4.25-15 degrees without a plate on a standard car, and you want caster on a 911

I think you are looking at the camber ecentric.

I think I see what you are trying to do now. Yes that is caster ecentric but it's not moving the wheel really out or in its moving the bottom point of the caster angle. But you want some caster. Yes you would also need to redo toe and camber if you adjust caster.

It is just turning the lower ball joint forward or backward, and I think your proposed idea will increase caster. I don't know what direction you are looking at it and don't remember off the top of my head which way that ecentric works.

I'm going to put KW V3's on my car soon and my wheels are to far out of the wheel arch so I'm looking for a solution.

Yes, you're definitely looking for some camber!

What tyres are you running? With road tyres and spirited driving, don't go over 1,5° all round. On track, especially with track tyres, you can go more.

Get wheels with the correct offset and width.

Camber is really setup and drivin style specific. I know a guy who ran nearly 3° negative on the front of his fully coilovered/swayed street-driven e36 M3 and still managed somewhat even tire wear, however, his street driving style was super aggressive, so the whole tire width was being utilized and maximized w/ the extra camber.

That could be if you drive hard enough. That is the idea behind camber is hard into a corner the tire will lay flatter with the road surface with some camber vs none, but most people don't drive like a maniac 90-100% of the time on the streets.

when i watched the alignment guy adjust my caster, the wheel moved longitudinally towards the rear of the car by about 5-10mm .... perfect to move the front wheel away from that annoyingly tight clearance from the front bumper/front fender joint.

when talking about fitting your wheels, we dont really care about KW V3's too much.

what width & offset are the wheels? and please dont tell us the diameter as it is irrelevant.

205s stretched over a 8.5" wheel?

Are you trying to pull off some type of stretch/stance fitment?
