View Full Version : Changing wheels at the track

How are you guy's changing wheels at the track? I have a small hydraulic jack and have been using the jack mounts under the sides of the car, but I'm chewing them up pretty bad ('02 330Ci). Not to mention it's not the most stable of jack points.
Is it possible to buy or make something to fit into the side jack points (like ont the stock jack) that would allow using this jack point less damaging and maybe more stable? Or should I be using different jack points all together?

Any other suggestions would be appreciated.

I use the diff to jack up the rear of the car:

Up front, I use the center of the front subframe. BMW AG kindly provided a metal puck welded to this spot:

As a result of my car being lowered with H&R coilovers, the fronti is too low for anything that I have except for the stock jack. On rare occassions, I'll prep my car at home and drive to the track with my Rs (i.e. A032Rs) if I'm running at PR/SIR. Most of the time though, I change my wheels with the stock jack at the track and do the other prep work like swapping out pads at home.

Try the Ultimate Garage jackplate Ultimate Garage Jackplate (http://www.ultimategarage.com/jackplat.html)



And never, never, lift the rear by the diff. Diff carrier yes, diff no :thumbdwn:

This is for an e36, I don't believe it will work for an e46. Is there one designed for an e46?

I haven't looked at the e46 jackpoint, if you're not sure, call the Ultimate Garage and ask.

Isn't there a jackpad under the car similar to the e36? I've used the jack pads and a low-profile floor jack with no problems at all on my e36.

yeah, mine are chewed up pretty badly too (i have an E46 coupe). i got myself a nice aluminum floor jack which already has a rubber padding on the jack, so no more chewing up the plastic.

if your car is too low to be jacked up, drive your car up a block/blocks of wood. i see many people at the track do this.

I love an unsupported dogmatism. Why shouldn't a car be jacked up by the diff?

That is a simple but excellent suggestion. I will do that.
My track jack has a small jack plate and is not padded. I may take it back and get another or fabricate some kind of rubber covered plate.
