Jul 15, 2015 When you take your vehicle to an alignment place you must make sure of the following: - You have a full tank of fuel. Your tyres are at the correct pressures (33FR/36RR for E46 M3 with standard 19's) - Your bushes (FCAB, RTAB, rear ball joints) are in good order, and your track rods are not seized up.

E46 M3 Wheel Alignment

Aspects of E36/E46 rear suspension design is that by adjusting the camber (which is easy to adjust) also creates slight changes in the static toe setting (which is very difficult to adjust). So by setting the camber and toe to a preset value, it is only necessary to adjust the camber bolts at the track to make significant. In this guide, you will learn how to calibrate the BMW steering angle sensor. BMW steering angle sensor must be calibrated every time you work on the steering system, front suspension, repair steering column, replace the battery, or replace the dynamic drive control unit. Quick Way to Reset BMW Steering Angle Sensor One quick way to calibrate the BMW steering angle sensor is to follow these steps. The BMW E46 was the best selling generation of the 3-Series. The rear-wheel drive sports sedan is one of the more complicated cars to align, but it has many service and repair opportunities. BMW 3-Series 1998-2006 E46 Alignment Specs.

I actually didn’t take a single photo of this entire process, but about a week ago I set aside the whole weekend to do the rear arch rolling. I knew this was going to be a little changeling, not because of the arch rolling itself, but because BMW decided to pack the inner lip of the rear arches with some kind of sealant to help prevent rust. That’s a good thing – I like their idea behind it – but it’s a nightmare if you want to roll the arches!

I did a lot of reading about the procedure, and the majority of what I said was take it slow, use some heat, and swear a lot! That’s pretty much exactly what I did. A combination of a couple of various chisels, a blowtorch, and a LOT of patience, and finally they were done. After over 1 whole day, I may add!

Finally though, my new wheels are now fitted – all around. The fronts just fitted straight away, no issues at all, it was the rears that caused all the headache

I’m really pleased with it though, looks fantastic. Completely transformed the car

And then fast-forward to yesterday, after about a week since the new wheels have been on, I went for alignment. I spaced out fitting the new wheels & alignment by a week or so to make absolutely sure that I was happy with how the car was sitting.

I knew the alignment would be a quite badly off, but -9 rear toe on one side! That’s impressive!

Final results

E46 Wheel Fitment

Not exactly what I was hoping for on the rear. We had a look into it and it seems there must be something bent causing so much negative camber (drivers rear). I’m yet to investigate that further, or if I will, but the excess camber is causing toe-in problems too.

I’m hoping it might be a bent upper rear wishbone (as that’ll be the easiest to change). A bent trailing arm is fairly unlikely as they are solid cast, so I think I’ll try a replacement upper wishbone first — but this is fairly low on my todo list, it’s not causing any untoward characteristics
