Rear diffuser installed - very easy, just a bit tricky getting the nuts on the backside of bolts in tight spots as my fingers don't fing as well as they used to.
Mix match intake also 'complete' as I installed the Whoosh Crossover Pipe and the Mountune High Flow Induction Hose - perhaps they'll help out, at least they don't add any bling to the engine bay.
I need to get the front skid plate back on and perhaps mount it a bit better with some rod supports to the front bumper crash beam - I'd like to have a removable splitter for use in summer and remove it for winter. It has to be functional though so that means I have to be able to stand on it, hence some sturdy mounting locations.
I received pricing for the CMComposite hood vents and it's reasonable so I'll probably order them up... I've got a stack of parts for winter install - can't wait to run an LSD in this car.
