Is it possible to give the LS430 negative camber with the stock suspension setup? I only wanna give it about -1 degree of camber. If this is possible how do you change it?

 

Negative camber?

On a road car??

Too much is not really recommended......

.....stability issues.....increased tire wear.

Here is a thread that provides wheel alignment settings:

Possibly some on the rear.

Very little on the front.

The figures given are using stock arms/components.

The amounts would be almost imperceptible to the eye.

There is not much commentary about negative camber here at CL/ LS430, probably because of the reasons mentioned.

It depends, of course, on how worn your original suspension is.

I would leave it up to your wheel alignment technician.

 

The specs already has -1° camber.

 

How do you read that? im confused on what its saying

 

Ive watch a lot of videos about camber and what i got from it was with street cars you dont want to go to much about 1 degree, they suggest .5 degrees negative or slightly more and said once you go about 1 degree thats when youll notice un even tire wear but if youre at at -1 or below its very minimal. I was thinking around -.5 - 1 degrees in the front and -.75-1 in the rear. I dont drive my car like its a sports car because its not, if anything its closer to a boat, but I dont drive like an old person, I'd say I drive spirited safely, so it seemed like a little negative camber wouldnt have an effect of the tire wear. Thats just what I was thinking

 

Were any of those videos LS430 specific?

If so, please share.

What size wheels/tires are you on?

 

These werent specific for the 430, or any car for that matter. I watched a lot of videos and they were all about multiple different cars not just one specifif so you can get a general idea, I know some cars, especially sports cars can have a bit more. And im on the stock chrome 18x8 rims with 245mm tires from the Euro tuned sport suspension. And I have 5mm spacers in the rear just to make the tucked stance a little more even to the front.

 

Sounds nice, any pics?

 

Just because someone has done a video doesn't mean it is correct or relevant for the LS430.

The LS430 already has -ve camber on the rear with each side between -0.75° and -1.75° (-1.25° +/-0.5°)
However the difference between the 2 sides should be less than 0.5°.

The fronts can be between +0.7° and -0.8°.

 

I mean yeah if you just drive your car in town under the speed limit and move like a turtle around turns I get it, but going around turns with speed negative camber will always help because you have more contact area on the outside tires. Not saying you need a lot but you always want at least a little. I mean thats part of the reason BMW's handle so well, they have quite a bit of camber from the factory. And if you drive it like an old person your tires wear out really unevenly

 

When theyre doing the alignment could you ask for the rear to have -1 and the front -.5? Or do they just get it aligned the best they can due to how your suspension wears out over time?

 

On the Ls430 rear camber can be adjusted with different length control arms which would not be part of the alignment. You can ask to have the front set to your specs, see what the overall results are and take it from there. Rear control arm changes would generally be for a lowered car to get the camber values in spec.

 

Maybe in their 5-Series and smaller, but BMW never made an M7 because the 7 series is a limo, just like the LS430.
The LS is a 2 ton car so will never need the kinds of camber that lightweight sports cars or race cars need.
Yes, you can do it (need to replace the control arms at the rear), but I can't see the point on a road-going LS as you would ruin it for normal road use.

I mostly drive my LS smoothly but I don't hang about and I occasionally like to throw it through some twisties and she hangs in there.
I like the air suspension because it helps with hard cornering, especially in Sport & Power mode.

 

Instead of fantasizing about negative camber I would, and do, concentrate on things like tire pressures.

From my earliest days being involved with car club level motorsport the importance of correct tire pressures was emphasized.

To help reduce understeer, I normally run about 38" front/34" rear in most situations.

For the track, pressures could be up to the mid 40's for sprints.

Spending some time experimenting with tire pressure in everyday situations will provide more advantages than minor wheel alignment variations.

I have a wheel alignment rarely, but I check tire pressures regularly.

Image is me in my first car the white car Holden(GM) Torana 173c.i. in 1981 at Sydney's Oran Park Raceway. - it was the start of a long association with motorsport and cars that continues today.

A direct involvement with motorsport(less now that I am older) has been a great benefit in getting more out of my motoring, which includes practical things rather than just mere theories.

P.S. It would be difficult for anyone to make the suggestion that I drive like an "old man".

 

I mean the m3 only weighs 200 lbs less and m4 is less than 300. But I see your point. Still any bmw no matter the size always has a good amount of camber, I don’t get how you guys are arguing camber doesn’t help with handling, it literally gives you more contact
