IND | Rogue Engineering E46 M3 Aluminum Lifting Block Set

This appears to be only for the Rear. No front use.

The front jack pads are fine to use with a jack, so no need.

Is the rear jackpoint issue primarily when you try to jack the car up from one of them (meaning ~half the car's weight is on it)? I almost always jack from the rear subframe so both rears come up off the ground equally then use the factory rear jackpoints for my jack stands (so only a ~quarter of the car's weight is on each point).

I never lift the car by the jack blocks. Rear subframe and front "hockey puck" on the reinforcement plate.

do you drive up boards or ramps to get enough height for a jack to get to the hockey puck? what's the difference between lifting the car by the jack blocks and resting the car on the jack blocks+jack stands?

[LeeForst]

I thought it was ok to quickly lift from one rear point in a pinch for a flat

Yes I put the front up slightly on ramps to get to the hockey puck when I want to put the front on stands.

I use a race jack on the front right or left jack pad to get the tire 1-2” off the ground, then I’ll use a low profile jack to lift from the center puck. Boards or ramps work too.

It is. The other E46s come with a factory jack that actually is made just for using any of the four factory jack pad locations.
The BMW accessory “Emergency Spacesaver Spare & Jack” kit come with similar jack and same use instructions.

even if you're using ramps, in the end you're still setting the car down on the pucks, so what would be so bad about lifting the car from the same spot?

The rear jacking points in the E46 Coupe cannot support the weight of the car when lifted with a jack, the entire metal structure fails and tips inwards. It’s a design flaw, convertibles and sedans in my experience are not affected by this.

[tnord]

I don't use the rear jack point other than to put the car on stands, but I don't think when using it you're really applying force equivalent to the weight of the car since at least two other wheels are on the ground. More like half the weight.

we could use something like this for the Z4/Z4M cars. Glad I saw this thread, will have to look around.

I have never seen this design change. Do you happen to have info/documentation of this being a flawed different design between Coupes and Sedans/Convertibles? The only thing ever seen was it getting rusted out on some extreme cases. And the rears tend to be more prone to extreme rust.
And BMW never posted a TSB about this afaik, and jacking flaw knowledge would be a severe safety issue. If it were a rust issue that’s another story. But a major design flaw at jacking points would need a safety bulletin no?

Both of my rear jack pads are bent lol.

BMW TIS only shows jacking up from the front center jack pad and raising the car on a four post lift. I could not find any info on jacking up from one of the side jacking pads.
