Stupid?

Lol might as well tub out the rear and do a vette rear end.

hehe jasper

do this man.



This is the next project for the silver car.

so this gives rear shock about 3.5" of extra travel? Why didn't you get a pair of Mustang Fox-Body shocks?

Trust me I wish it were that easy because it would be done in 2.5 seconds. Lol. But, they won't support my 700lb spring rates. My shocks are from a ground control coil-over kit. The mustang koni's (off the shelf) are not the same as the modified/re-valved ones that ground control sells for their kits.

And its about 2.25" (+ or -) travel to compensate for the length of the shaft of the e36 m3 shocks.

wait wait wait wait wait so those GC's didn't shorten it by enough so you used a spacer and a long bolt too? Is that spacer thing hollow inside? Rear shock towers fail with regular shock mounts, if that's hollow and thin it will probably crush it or it will cut into the shock tower over time. The GC thing looks at least 2" taller than stock was that alone really not good enough?

The GC tall rsms are only an inch taller than the originals. The total length of the spacer that I added was another 1.25" (+ or - .15") for a total of 2.25 inches which is need to match the stock e30 shocks.

Yes the spacer is hollow inside and no it will not cut into the shock tower and again, the stock rsm plate acts like a reinforcement from the bottom.

I opted to go through with my original plan for safety issues. I didn't want to take the chance of my shocks bottoming out, ever.

Here's another picture.



I'll snap a picture of the bottom side when I have a chance.

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.

i made some from surplus pipe from a welding shop.. $ = free, and about an hour of time

[jahnaboi]

Nope. Two day ground shipping from GC, pretty hefty bill for these I should add. Total was 171 shipped.

Overnight from Japan?

[jahnaboi]

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. =)

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

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

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

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.

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.

Man, I wonder if anyone sells these?

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
