I think mine sits further back, as I indented my firewall by about 20mm, but is probably slightly higher, as i haven't touched my swaybar. (It does have what I assume to be a 120y sway bar in it) I might have a few issues though, as the engine sits fairly close to it. How do you go about spacing out the swaybar?? just put some 10mm spacers in made out of aluminium plate or something?? (that shouldn't be hard... uncle works for a boat builder... )

Mine has a modified sump which helped with x member clearance. someone cut out the back half of it, and raised the back 2/3's of it by 10 - 20 mm. I can't see any problems with that, as long as i change the oil a bit more frequently.
