Front Suspension 1980SC

[Eomak]

Hi, i had this car a few years and its lowered pretty low. I've always had this problem with the front right tire would wear down quit a bit on the inner tire like a flat spot and start to give the steering wheel a real shake effect at 65mph after few months from a new tire. Other side and rear tires stay ok.I would just buy new one every time thinking car maybe to low.1 year i took it to porsche mech. with new tires where he noticed and felt a small bump lump feeling when when car is rolling.I still drove it again couple years after that like this.This year i put on new turbo tie-rods and bump steer kit new tires and four wheel aliment at same ride lowered level.Feels pretty smooth and don't notice anything rong for the first few weeks but then i start to notice a bump lumpy feeling like a rim is bent but its not when rolling. Maybe car been hit in front end bye another car and they fixed it as much can cause too expensive to fix? I notice the car has new front right fender too.I would like to keep the car put alot money into engine and the car is in show room condition owned bye high class auto shop before me.Do u think this is fixable? like maybe it just needs new A-Arm or something? i just don't want to buy parts it maybe doesn't need. Could it be the body front end thats out and needs like high tech body guys to correct it meaning more then car is worth? Dont know to much about how suspension works.Or simply the car is just to low but looks sweet that low. thx

Another case of looks over performance.
What is the height? Fender lip to floor front? Rear?
If you are less than 25" front and 24.5 rear, you'll have problems even with a bump steer kit.
What alignment do you have?
Camber front? Rear?
Toe front? Rear?
In Vancouver: What shop are you going to?
Who did the alignment? Post the specs.
If the tub is twisted, it would have shown up during alignment.
I would check the bolts holding up the crossmember subframe.
Worn ball joints can also act up funny but a competent shop would check all components like shocks, bushings, ball joints etc. and replace/adjust before an alignment.

Hi , not sure how low it is ,but even so just because its lowered would it cause just the 1 tire to wear that much? Weissach did it for me .He told me was to low to get into spec but i told him just try to get the front as straight as possiblyand make sure everything safe for driving.I guess the only way is to bring the height into spec and go from there which means big$$ again.

[911quest]

possibly a bad strut housing the spindle could be tweaked causing the excessive wear on the inner edge

So, just get a tape, put the car on level ground, measure the fender lips to the floor and post what you find front and rear.
Weissach must have given you a printed spec sheet for the alignment; post it.
Camber front and rear?
Toe front and rear?
Stuart deals a lot with "Looks over performance" and has his own opinion on the matter.
You cannot imagine how well a 911 handles with Euro height, mild-sporty 4-wheel alignment and corner balance.
Post the numbers so I can get a better feel for your car.

Can having the car to low cause one front right tire to wear extremely? Thats what my Porsche mech. said. He looked at everything and found no evidence of bent parts.And told me rising the car ride height well take the problem away. Just wanted to C if this could be true before i spend more money again for something i should have done from the first alignment job. The other tires are fine. Everything's stock 205/16 tires fuchs in front.

It looks to me like Gunter is trying to help by asking specific questions that need specific answers. If you want help and possibly save some money, answer the questions and lets see where the discussion goes. You have to eliminate all possibilities and narrow things down.
Lowering the car can and WILL change your corner balance which WILL affect tire wear. Toe and camber will also have an effect on tire wear.
So, if you want some help, get out your tape and go measure and if you have other alignment data, lets see what you've got to work with.

Hi, the measurements are in M / passenger side rear 60.2m front 62m. / Drivers side 61m rear / front 62.5m . The lvl is uneven not sure it it was profesly lowered. Sry no # they just tried to get the aligment as close and straight to spec.

[Mysterytrain]

62m in the front is a bit high..approx 2440 inches. I would lower it some.

[Mysterytrain]

.62 meters is something like 24.4 inches which is about an inch low. I think the 'euro height' is typically 25.5 front and 25 rear which would be .64 meters and .635 meters.

Man, let's get it straight.
We converted to Metric 20 years ago.
60m????62m?????
You mean cm, not meters.
As for the specs on your alignment, Weissach would still have the data in their computer. All you have to do is call and get them.
I am pretty sure that Stuart would have asked you to sign a waiver if you insisted on some crazy settings.
It's laughable to ask the mechanic to just whack it down without understanding the principle behind a 4wheel alignment.

If you expect help here, get the numbers and specs without dragging it out much further.
Without specifics, what assistance do you expect here?

Wild guessing is a waste of time.
