From my trans to my wheels, my axles go uphill at a 10 degree slope. Is that too much?

They angle forward a bit also, but it don't appear to be that much.

That rear end must be sitting very low. Badly gagged springs?
914Sixer
Looks like aftermarket springs with spacer blocks.
partwerks
So maybe need new springs?

Hard to say. How does the car sit ? Cant see that much. What kind of shocks? They might be Bilstein with adjustable perches. If so adjust them upward. I dont see spacer blocks. Can you take a good picture with the flash on to show the spring?

Check to see if there's another notch to push the perch up another inch....
Andyrew
Can we see some pics of your trans mount and the spacer block on the trans side?

The v8 conversions move the trans back 1.5" and your forward to back looks good. The angle from the squat could be because the bolts arent tight enough and therefore the transmission is hanging down or the back is simply too low. which judging from the angle of the trailing arm is not the case.


Lets see a profile of the car as it sits.
SirAndy
Actually looks like the transmission is much lower with that conversion.
The problem is that with an angle like that at rest, it's only going to get worse under load.

I'd be worried about the CVs falling apart if you put some serious power through them.

Ya I think the trans is falling off the hangers. Pretty common on the V8 conversions.

Most conversions put the trans in the stock location just moved back.
partwerks
Maintenace guy at work, and I made a new trans mount on the back to replace the one the mechanic made that was too weak, and one side broke.
I think he reused the old Subie WRX engine bar. The adapter plate I had made at kitcarchassis.com.

Hopefully pictures will help.

Your transmission should be a good 2" higher in the chassis, there's plenty of room above.

Also, why are your adjustable shocks all the way up?

How short are those springs? They better be tiny ...

Probably cuz when ya pay someone to work on it, I would expect them to know more about it than me, but from lots of things I seen. That wasn't always the case.

Are they suppose to be in a different position.

Those springs look waaaay too short, which is why the threaded collar is located on top of the highest groove and then the spring perch is on top of the collar.

I wouldn't be surprised if the part of the collar where the perch sits right now is actually above the shock body and thus has limited support.

Hopefully that's just the angle of the picture though ...

Its going to be real low when those rear mounts pull thru. They need the factory washer on the top side of the bolt.

I just have smaller flat washers on the upper trans mounts, and so are you saying that I need washers with a bigger outside diameter so that it doesn't sag?
BIGKAT_83
This is what you need on the top of mount.

This won't do any thing for your "sag" the way it is now if the rubber broke your whole engine and transaxle would fall out.

Fix this before you drive the car

Do I need the round one also, or just the rectangular one on top?

Would there be some kind of adjustment to allow the trans to be moved up higher, or how does that work with it being attached to the adapter plate. I had it made at kitcarchassis.com

Not sure how to do that with it being tied into the adapter plate?
euro911
I just noticed you're not running a 901 trans ... I see your dilemma now
partwerks
I wonder if the adapter plate could be made with an offset, so it could come up higher?

Input shaft on the trans can't move in relation to the position of the engine, so no.

The steel plate mounting the trans to the trans mounts could be bent to raise the back of the trans...

How low is your car? Raising up the rear would be the easiest option.

Something else just came to mind idea.gif ... I'm wondering if you'll need to shorten the axles once you raise the trans upward confused24.gif

What happens when you lift the car? ... is there any binding on the axles when the trailing arms move downward?

I haven't checked, but custom axles were made for it.
I have a Craig Davies remote WP, and wonder if the engine could still be moved ahead a tweek, then maybe could raise it up some? Right now the back is about a thumb's width at the back of the engine bay, towards the top from hitting. I would imagine if I was able to move the trans up, to some degree, I would have to take some off the length of the axles.

Possibly.

Hard to tell how much 'wiggle room' you've got from the pic angles we're seeing. How much room is there between the sides of the trans in relation to the mounting points?

Also, measure the clearance above the trans to determine how much it can move up.

See if something like this will work for you. Modify the existing bracket to lower the mounting points on each side of the trans while leaving enough clearance that the top of the trans doesn't hit the trunk floor.

Looks like at the top of that adapter plate, there would be at least 1 1/2"-1 3/4" it could go up yet. Just eyeballing it.

Got my top plates in for the mounts, but no difference than before, other than won't pull through.

These shocks and springs are at least 13 years old. I don't know how long before that, the previous owner had them, and so maybe it is time to change them out?

Can we get a pic of the side of the car to see how low you are?

I will make a note of that for Saturday.
Andyrew
It's low but I've seen lower. I say modify transmission mount.

I love that color!

You can pick up another 2" if you delete the Porsche factory donut hanger at the trans and use the Subaru OEM trans support.
