m3 strut hats?

Hey guys I was reading this thread:

http://www.bimmerforums.com/forum/sh...or-your-E36-M3

Specifically this part:


"Option #2: BETTER
Swapped 96+ M3 upper strut mounts
- (free if you have a 96-99 M3, or about $75 used on bf.c)
- relatively easy to install
- gain about -2 deg. camber (about -2.75 deg total per side 95 M3s, 96+ M3s will gain more ~3.3 deg per side)
- camber not adjustable (what you get is what you get)"

Would this work for my 98 e36 bmw 328i? Or do I need m3 struts? Is there a place to order these or do I need to find used one? I'm not sure I fully understand what he is doing here.

Thanks for your help,
Kevin

It would work on your car. Why are you seeking to add negative camber?

For performance. I am trying to make a more track type setup on my car. Somewhere around 2.5-3 Neg Camber front, 2.5 Rear, 0toe front, and maybe 0.1 toe in rear or 0.05

If you need to replace the struts and were going to pull the strut assembly anyway, the M3 upper strut mount is a good way to get some additional negative camber. Instead of being in the center of the mount, the M3 bearing is offset toward the center of the car so it moves the top of the strut inboard which increases camber. For the amount of negative camber you're looking for, shimming the lower strut attachment point can achieve the same amount of camber change at much less cost and labor.
Both Turner Motorsports and Bimmerworld offer a shim kit. The Turner kit is a bit easier to install since they give you individual shim washers, but either can be installed in less than an hour.

Thats good to know, i was planning on attempting to shim it. Not sure if ill run into tire clearance issues I have 17" 225 -45 tires. What size bolt is that? I can grind some nice flat washers Just need a longer bolt. I have it all apart right now changing control arms.

Thanks

The bolts for the lower strut mounting are M12 x 20. You want to lengthen the bolt by about the same amount as the thickness of your shims. (Item 3 in this diagram). I had the same size tires on my E36 but I had ET20 Style 5 wheels so I had some built in clearance. Whether you'll have any issues will depend on what offset your wheels are. So long as you're got a bit of clearance between the shoulder of the tire and the lower spring mount you should be OK.

Yeah sounds good I'll have to check it. Im not totally positive of the wheel offset as I bought the cars with the wheels on it. If i buy some bolts from a local hardware store do you think I would be okay? I may also add a locknut.

Just ensure you buy same or better grade bolts. Lock nuts won't work for the two bolts in question, they go into blind holes in the hub casting. You do want to ensure you clean the threads in the hub and clean the bolt and use Red Loctite.
