Steve,

I think LCI addresses some of the pre-LCI foibles however have you driven any 'fettled' M135i's ?

If not, then you aren't best to make your generalisations about tuning being a liability.

Stock brakes are fine, springs need firming up [a la M235i] ie H&R/Eibachs or Birds B1s and JB4 adds some more gumption to make the best of the simple chassis upgrade. All in <£1000.
