Diff <-> Engine alignment/height

[mark]

In my opinion 15mm difference in height wouldn't be a problem, apparently having them dead straight causes brinelling (not sure on spelling!) which causes joints on the prop to wear out faster

If you picture a heavy goods vehicle prop they are always on an angle

As to how much of an angle you can run with a short prop on a roadster i'm unsure, but a phone call to dunning and fairbank will give you a good idea

Your sump is a touch lower than i would personally like but your choice of 18" wheels will help with this a little

As with most things its a balancing act, engine height, prop angle and ground clearance will all end up being a slight compromise by the looks of it, nothing that should cause any major probs though

A sump mod may cost you and cause you hassle, but do it right now or it will bug you until you do! then you wont have to make any compromises!
