the CV axles don't really work. also, with the shorter axles the effects of lowering the car on them will be worse, since the angles will be so much steeper. and it's still over 2" too far forward to fit easily.

[Nisse Järnet]

Oh yeah i missed that, its 1" more forward than the E34? :S

[Nisse Järnet]

BTW, does the E30ix axles line up straight out of the pan to the hub or do they tilt a little forward/rear? If you know what i mean :)
I just put in M3 offset CAB and is a little worried of the angle...axles is pointing forward :P

[nando]

they are pretty straight

a few mm forward isn't going to affect anything, just look how steep they are when lowered. I've run M3 offset CABs for over 10 years.

yeah. :(

And the E34/E53 pans already require the rack to come forward 1 1/4"... I don't think one position of the rack can accommodate both pans.

I got this E30 ix pan. ended up paying $34 out of pocket, not too bad. :)

Here's my thought.. Cut off the flange and the front of the pan (warning; MAD paint skillz):


cut out the sump and leave the flange on the N52 pan:


bolt the N52 pan to my transmission with the transfercase attached. I'll need a front diff for lining it up. basically, file and trim until I get the front diff in just the right location to properly line up the front driveshaft. tack it together somehow, then take it somewhere to be fully welded.

I may even be able to live with the 4.10s for a while, saving some cost on newly built diffs. It might even be just fine, with the mods I want to do I think a 7500rpm redline is pretty realistic, that might work OK with the shorter gearing. the M20 just sort of ran out of breath even though I could rev it to ~7200.

In u will measure more accurate but it's more than a few mm. They already sit at a slight forward angle without the offset bushing :S

yeah. :(

Not good :P

[nando]

it's a pretty small change really. I think it's about 1 degree of caster, the ix only has 1.5 degrees or so to start with (RWD cars are like 10-13 degrees).

Sounds like a good plan! I want to do something similar with the X5 stuff..

I got the camber plates so I'll gain some caster there.
I'm just afraid the forward angle will be bad for the axles as the car already is lowered :P
But before replacing the new bushings I'll measure the angle of the axles and take it from there.

[nando]

like I said, I've run them for 10 years without issue. the CV shafts currently in the car have ~500,000kms on them!

[Nisse Järnet]

Yeah but I think mine is probably twice the angle compared to yours :S

[nando]

why do you think that? My housings are like 4" shorter than stock. :p

[Nisse Järnet]

No I meant the forward angle :)
