Getting ready for the first track day in the M2 next Friday. Had the Vorschalg camber plates installed, however I'm not sure about the alignment.

After reading / searching quite a few posts here it seems the consensus is that best for track is -2.75 and zero toe. I may have made a mistake when I left instructions for the alignment to be Stock Toe (0*:06sec) when the plates are at street camber setting.

That now means that when I slide the plates out to max neg camber (about -3 degrees) the toe is out / neg 0*:20sec or about 0.33 degrees.

Just curious / opinions about how bad that will be in terms of front tire wear and drivability for one track day. I'll likely get another alignment done and shoot for less toe-out (or zero toe) for track camber setting and just keep it there.

Street setting:


Track Setting:


Kind of surprising to see that much change in toe when swinging the camber plates from stop to stop.

Camber and Toe are connected. I wouldn't be changing your camber once it's been aligned or your toe will always be off. I set mine to -2.75, toe to a hair toe out and left it.

Wear will be shortened to about 2/3 from what you would expect from a normal less than 0.5 -1.0 setting.

They are basically due to uneven weight and load at corner distribution at certain surface of the tire where normally tire should give all around surface contact to the road.

If you track yours, would not be a big deal as it would wear out very easily anyways unless you have separated wheel+tire set for track only use.

Changing camber setting will alter toe setting as well as they are related. Meaning that you will have to get alignment every time you change your camber/toe setting. This cost will basically will cover way more than simply getting tires more often especially when you are having many track sessions in good weather season.

Stay at 2.5-2.7 and all it a day. Change the tires when its needed.
Get good track wheel+tire if you are keeping your car long and want to track at least more than 5-6 full track days per a year. Just my 2 cents

If you have a good alignment rack operator/shop, you can work with them to come up with the sweet spot for street setting vs track. On my E46 a long time back, it was possible to set the camber at -1.5 for the street and put the toe setting at midpoint in the factory range. Then when moving the plate to -2.8, the toe would move to a toe out setting that worked perfectly (don't recall the toe data as it's been so long).

I used a punch to lightly ding the camber plate at each camber setting to allow repeatability. We then moved them from track to street setting, back to track setting, and back to street setting and had excellent repeatability.

Being able to run a reasonable camber and factory middle toe setting on the street really helped on that car with uneven pavement and such -- tramlining was much less than when at the track setting, and high speed straight line tracking was much better also.

Thanks! I have a separate set of track wheels/tires. Brought the toe back in a little (one full turn on each tie rod) before the track day today and it handled GREAT.

I'll take it down to an alignment shop and dial in zero toe and just keep the -3 camber I think.

I'll monitor the inside wear on the street tires and adjust my plan from there. (then upgrade the street tires to PS4S)

Do the corner balance if u r taking it to a shop. Make sure to do it at reputable one

That's significant variation in camber from L to R
