Sump Clearence

[skov]

I've gone for 40mm below the chassis rails, as per Spud's advice.
I am terrified about grinding the sump off, but if you position the engine any higher you'll struggle to get it under the bonnet!

I don't know if he's tried it or not yet, but Johno has done a load of research on chopping the MX5 sump and was planning to give it a go.
