I got a quote for four custom spacers for about 300 dollars! Gonna go with the summit racing aluminum ones. How are those working out btw?

Not a thing. After over 10k miles, several track days, and a few pothole hits I put it in for a post-season inspection. The same foreman who raised those concerns said the front end was solid.

Anyone find a good place to procure these washers? Any luck with a nearby Home Depot, Lowes, or Ace Hardware?

Summit racing aluminum ones are inexpensive

Would you happen to have a link or item number to the exact one you used?

Not many places have a washer that's 1mm in thickness.

I have the f80 lcas installed and the turn in is awesome and understeer basically gone.

I am stuck between f80 TSs and pressing Turner monoballs into my stock TSs. conflicting opinions on if the F80 TS does push the wheel back to center of the wheel well or not.

anyone have a recommendation on which option to take?

This is the closest I've been able to find. It's a hair thicker than 1mm.

Hello BMW Experts!

My only problem with putting in the M3/4 LCA is the small amount of screw left on the tie rod adjusters. Various people & venders (Bird, Turner, ECS) say 'no worries!', but I don't really like lots of toe-in for my front tires, just a little.

Do any of you muggs who have done this LCA change know your front toe-in, or if your alignment guy put you in the 'more toe' part of the allowed range in order to get the tie rod screw further in? Or, are any of you running in the 'less toe than median' of the allowed range?
Clear as mud?

So would someone need shorter tie rod adjuster or longer tie rod adjusters as a result of this modification?

A little more would be nice!

My guy aligned me right down the middle of specs: 0.11
Toe spec is 0.08 to 0.15 for my '17 330i.

Hello BMW Experts!

I now have the M3/4 LCAs in. Previously, I had them in, but took them out.
I was not getting proper self centering the first time I put the M3 LCAs in. The steering would not fully center after some turns, and I had to complete the centering myself. This did not inspire confidence.
But that was last time. This time I went to an expert alignment shop, and the car feels great (this after getting an alignment characterized as, "looking like Ray Charles did it", by a Forum member, at the other shop). The centering is improved (from more caster?), & the turn-in is sharper. I bet that when I take it to the mountains, the front won't scrub as much either!

"My name is LittleBear (or Murf or Tom or...), and I now approve of this mod!"

My tension strut bushings started giving up on me so I installed the F80 TS with the aluminum spacers from Summit Racing. It did push the wheel back roughly half of the way. When you're ready to touch the tension struts I'd go for the F80 arms. If you still wanted a monoball kit you could press in the F30 spec ones and forget about spacers.

More info in this thread.

Part #31216856535 / 31216856536 are compatible with X Drive

I have no idea what the complexity of installation is though.

Is this the whole hub? RealOem talks about the pivot bearing and camber correction kit. Eccentric bearing? Shims to correct camber?
I would be willing to try but if it's the whole hub, I'm afraid it will be too expensive. Pre-owned part might be an option but how can you tell if a vehicle has an -30, +30 or 0?

Can you send the link for the specific Summit Racing spacers/washers you used?

Each of those correction part numbers is actually a different whole new hub. I bought used ones from DVC .

Hrm. That's a bit confusing. The picture of the item on Summit Racing makes it seem like it's a set of spacers that you are getting but the description seems to indicate that it's just one spacer.

So they need to be .25 inches (or ~6.36mm) and .50 inches (~12.7mm) thick. Are you sure that's the correct thickness?

I recall reading that people were using spacers around 1mm thick on the 2 Series forums.

These are the exact spacers used by many in the thread I linked earlier for TS installation. I suggest reading through that one.

Each item is just one spacer, the product picture is the entire KYS-100-377 lineup. 1 and 3 are the ones you are purchasing.

Some people have used 1mm spacers on the LCA, I haven't and haven't had issue.

So the spacers you are using are, indeed, significantly thicker than the 1mm spacers used on the LCA.
