How thick are your engine spacers?

[Mike B.]

Mike, with those spacers did you have to any other mods to fit the euro headers?

Thanks

Brian

Just the spacers, and you have to knock in the passenger side firewall a bit.

So you took the plunge with the euro... Nice! (what did you use for a brake booster? PM me.)

I didn't notch my subframe and had to use 3/8th inch spacers to clear the headers. I have a spare subframe that I may notch depending on how it handles at the track.

big D did you put the mounts in the same hole the factory ones sit in?on AKG they use the slotted hole for the mount locations, maybe that lowered yours a tad from that...

No that's what I did too - the other way requires elongating the primary hole. That would actually put the engine higher, since they're closer together so the rake wouldn't be so great. I'll see, maybe I didn't even need the driver's side spacer. Perhaps if I take it out it'll fix things, if all I really needed was some elevation on the exhaust side.

Well, I detailed this before, but in an 89 325i with 320i booster, I used no shims.

On a 91 318is with 944 booster, I used 3/8" shims on both sides, to clear the manifold on the DS and for the stock M50 downpipe to clear a stock swaybar on the PS. Spacer city! I should have slotted the PS mount a hair, but I decided to scrap the project.

I've got the cylinder mounts with a 1/16 washer to clear my relocated steering rack and to help with the header-subframe clearance. I also had to knotch the subframe to clear the euro headers.

1/4 inch spacer on one side and shaved intake manifold fins to clear stock booster =D

[dougsic]

Just one

Only one spacer on the passenger side. Headers, green e28 mounts, THR cabs. The header actually cleared without a spacer at all but it was close so I used this washer.

how's 1/16th inch aluminum plated fabbed to the shape of the mount. There absolutely NO reason to go with 1/8 or over 1/8 with the 5er mounts

[golde30]

i used 1/8" on the passenger side to make the ebay headers clear the subframe.

3/4", holy crap... in which areas was this primarily? Other than that, I just find it strange that BMW would change such little things year to year, or that it would accept manufacturing standards to such varying tolerances.

mounting of the strut bar usually is the first place you will notice it. heck, even ireland sells 2 different lengths. cheers, jason

[BigD]

not all of these cars / parts came from the exact same factories / parts manufacturers. even the strut towers have different overall dimensions between years. you can find a 3/4" difference between two non-wrecked / non-tracked cars. also, i know of (3) different m50 intake molds. personally, ive used everything from 0 spacers up to 1/8" spacers. all depends on how it fit. cheers, jason.

No, I'm implying your car has been hit at some point. I've seen mulitple cars with no clearance problems whatsoever, going on your posts, you seem to have a multitude of problems, indicating that the car is probably bent.

-Charlie

No history of it, on record anyway. Which of my posts indicate that my car is bent?

For what it's worth, the ORCA CD specifies 1/4" spacers for the motor mounts.
