want pic of under diffuser

Looking at ways to attach my DIY diffuser. The rear bit is not a problem, but there seem to be many ways of attaching the forward part. What do people do?

Thank you as usual!

Here's how I did mine after inspiration from adithorp

There's rivnuts in the diffuser that I can bolt to through the plates.

Surely it should line through with the rear edge of the floor to ensure a smooth flow of air under the whole car?

I would assume you would either bolt to the rear edge of the floor or add some rivuts to the rear chassis/floor rail.

Mine's like cerbera's (it would be 'cos he copied me). Tabs on the back of the floor attached with rivets (same ones that attach the floor will do). The diffuser then slots on top of the tabs (flush with the floor) and secured via rivnuts in the diffuser. It's pretty secure at the front even without the screws. In the middle there's a couple of rivnuts in the corners of the diff cage and then pylons through the rear skirt at the back.

Erm.. Don't forget the underbelly tray for the engine compartment AND the full with ground effects front air dam /spoiler.
Aero attempt on a 7 type Kar are iffy to horrific.
Many owners, over the last few decades have tried and tested various add ons..with surprisingly poor results.. as in it messed the handling.

Yeah, I know it's not really for go, but for show. I do know that without my flat front, the front wanders at speed. There is already a central ally panel, so air is not disrupted all the way down; the extra diffuser bit is just to direct it a bit better.

I know we are dealing with bricks here, but you have to do something other than wiring sometimes. Wiring has taken up approximately 90% of all my build/maintenance, and I'm pretty sick of it at this point.

BTW that pic is exactly what I wanted. Thank you!
