Stupid?

Since I have 318ti trailing arms I'm going to try doing that to those. I have a tig welder and need to practice on something to put it to use, so this will be a good little project.

Wouldnt it be ten times easier to use a upper strutmount that goes farther into the trunk like i've seen vw guys do? And i saw a picture of a GC part somewhere, although i think it was just a prototype

318ti axles with an S52? Have fun breaking them if you're hard on it. ;)

[jahnaboi]

You didn't break yours. So I don't see what the big deal is. Using 318ti trailing arms doesn't require to use the 318ti axles.

Hey man, if it works more power to you.

Post pics! :)

Actually I broke my left axle 3 times if I remember right. :)

And yes, you do have to sue the 318ti axles.

Actually you can't use 318ti axles...the inside where it bolts to diff is smaller diameter. Maybe you can use output shafts from ti diff too, or maybe small case e30 diffs match, I dunno.

Anyways about this idea...yeah bad idea. If you brought it to a good welder they could make it work but I wouldn't trust a booger welder, shits thick.

You are also going to be changing the angle that the shock sees but I think it would be alright as long as it's not moved so far that it interferes with the body.

And finally of course you can buy just koni rears where did you get that info?

P.P.S I ran e36 m3 konis on e30 m3 springs (not too low, tire about flush or 1 finger over late arch) and never bottomed out once. THey were bottom not top adjust too...they make top adjust e36 konis now? If so I'll figure out a custom shock mount and run those suckas.

[MR 325]

Yes, I believe I also has the 318ti diff flanges.

Yes, they make custom top adjustable rear konis (from gc kits). So I'm scrapping the whole rear bolt bracket idea. Its totally do-able but, it would just look straight up ugly as they would stick out like a sore thumb when looking at the rear.

I lined up my e30 bilstein sport shock with the e36 m3 koni's and measured the difference. The difference is 2.37 inches +/- some. I really want to run these e36 m3 koni top adjustables, so I'm going to think of some kind of custom shock mounts.

Do you think mounting the rear shock mounts on top of the strut tower rather than bottom but with a spacer that seals between the top of the strut tower in between the raised rsm would suffice?

[jahnaboi]

Here's a quick mock up. It shows the rear shock mount on top of the shock tower rather than under, with the spacer being bolted in between. What do you guys think? Think it'll work? I do think a reinforcement plate would be necessary at the bottom of the shock tower.

I currently have e30 GC RSMs where the bottom is perfectly flat. This would allow the spacer to seal with a gasket maker material. It would be necessary to drill the holes of the urethane larger for the e36 shock shaft.

[bimmer630]

I was asking somebody about this same setup recently, a guy who races an E36, and he said hes seen a kit from GC that raises the shock mount just like you wanna do. I couldnt find it on their site though

[jahnaboi]

Man, I wonder if anyone sells these?

Wrong. You don't have to use them. You can but it would cause complications as its literally longer.

True but using the axle would be about an inch too long which would cause the bearings to bind to the housing under load. Which is probably why Matt snapped 3.

Yes, I believe I also has the 318ti diff flanges.

If you do it the wrong way.

Here's what I found out playing with my 318ti stuff.

I used the stock e30 axles on the 318ti trailing arms.

Removed the old TAB and replaced them with my IE street urethane TAB without a fuss.

I also was able to retain the stock e30 abs sensor on the 318ti trailing arms using a spacer about 5 - 6mm. The spacer required can very. You have to make sure that there is about the thickness of 2 sheets of paper (0.2mm) clearance between the toothed ring and the tip of the sensor itself if you want it to work correctly.

Still using the same large case 2.93 lsd I've had in there. Everything works.

As for the brake pad sensor, I'm retaining the 318ti's wires + plugs as it would be cleaner and running the wire in a parellel sequence with the abs wire + gromet. Wiring the brake sensor (lining) from under the seat and removing the big nasty line. Makes for a cleaner install and allows the 318ti plug not to interfere with the trailing arm or anything when trying to splice the existing wiring.

I found a solution to run my e36 m3 top adjustable rear konis in my e30.


not mine but bought the same exact ones brand new. Should be in by tomorrow morning.

Yay. =)
