Moving the steering rack forward? Subframe mod...

[DesertBMW]

M50/S50/S52/M52 Oil pan extends to the left making it imposible to fit to e30 even if the subframe is modded for clearance, this is because of the left ball joint that bolts to the subframe.

But M54 oil pan does not extend to the left, instead it extends straight down, this make it possible to fit into E30 with subframe mod and moving the rack two inches forward.

I've been dry fitting M54 oil pan and it is totally possible to fit the M54 oil pan in there without doing any mods to the oil pan, and good news is that M54 oil pan will work fine on older M50 engines.

I just wonder if the steering geometry would be greatly effected by moving the rack forward 2 inches?

Wow that would be awesome not to have to change my pan and pick up.

Will be watching this.

Just read a bunch of stuff on Ackerman steering angle.

What I can tell is it will make more bumpsteer and sluggish/ number steering. Both can be countered with more caster (m3,treehouse cabs) and a faster rack.

I'll keep a eye for a front sub frame. To see if I could mod it and move the rack forward and mock it up on my m54. This is awesome.

Pictures of what you are trying to do? Are you planning on moving the whole subframe forward, or just the rack?

Paging Japandrew... oh wait

Lulz.

I'd much rather swap to another stock oil pan than modify my subframe and relocate my steering rack.
