I am not going to say that I am an expert on BMWs or an experienced mechanic. But, I worked on cars that I owned for over 8 years (4 BMWs 2 are M3) and this is the first time that people around me cannot even get me an answer. I have been doing research and trying to find out what is going on for a while now. However, I still not able to find out what is the problem or just due to after market parts. Before I go for KW or most likely Ohlines with front and rear sway bar up grade, I would love to know if this is the problem from the parts, installation, or something else.
Car drives and handles well before 65MPH. It will have the shake appears by going with higher speed. Some time it shakes more, some time it not as bad and more like a vibration. Also, car seems like having alignment issue too, it will pull to right or left, but right side is more often.
Parts used:
Megan Racing coilover with the stabilizer end links come with the kit.
Stock sway bar.
Lowered and car sets about 26 inches above the ground, so it is not slammed at all.
OEM e46 competition package 19' wheels with 275/35/19 and 295/30/19 and in the fronts have 20mm H&R spacer.
Things I have tried:
1.Alignment done twice by two different shops and they are the shops you need to go in Twincities area, both are 5 star shops. Came back with the same spec sheets and been asking at least 5 expert on this and no one said I have alignment problem.
2. Thought was a tire pull or balance. Since I just have new tires put on, so tire ship get me another new set to try which is the same, also balanced the tire three times already. Nothing has changed. Maybe I should find a place to do a higher speed balance?
3. There are no problem or issues on the wheel, also check twice at the tire shop.
Things I have questions with:
1. When install the coilover set I found that e92 front sway bar is different than e46 sway bar. After release both sides end-links, it stay still and will not move with any angles to fit with the new/shorter end-links. Good thing is the gap/overlap is not much, so, I still able to put them in with a jack, but don't know if that will be the right way to do it. Is this a installation mistake that I made or that is how the sway bar designed?
2. I did torque everything with the recommended specs. I assume that the car do not have too much tension while turning, but it clunks (sounds like the sway bar is turning hard on the rubber bushing then clunk when the bushing cannot hold the position) if I turn all the way right or left. Is this related to the last question, or something else might have problem?
3. Jack up the car and try to find out what is wrong or if anything that I have done was not right. Then, I try to turn the steering wheel around while both front wheels lifted, I found out that the steering wheel will not turn freely, Max I can turn is about 1/3 of a lap on each side with a lot of force applied to it. Also, it will counter back itself, but not back to centered position. Is this the same as other e92 m3s? (Ignition is on position two but car not running)
Here is one post that I found a lot people can get help with. However, I did not see anything from 1-10 applies to my car. Warranty still with the car and the breaks been checked as well. I think all these problems can give you an idea that there must be some funny sh!t going on with my car.
