Check out the PARTS FOR SALE, 2ND GENERATION SECTION.

 

Did you ever do any more conclusive testing with it on the street (i.e. vs. speed bumps and the like), and what suspension mods do you have if any, the way it sits on your S4 is nice and it looks like there is plenty of clearance! Also... are you planning on making more?

 

Clearance hasn't been an issue. My front lip and underneath muffler brackets are 5 1/2". So far so good. I have to creep on an angle to clear the front lip sometimes on big angle approach ramps.

I'm sure the ramp of scraped ground effects is lurking out there somewhere.


I have done several velocity air flow models in CAD. It looks like this thing really sucks.




Version 2.0 could have some small elements to improve this.

I would need to have 5 committed buyers to do this again.

 

This is neat! I'm in AZ and have a rear diffuser in my to-buy list. My only question if is you have any plans to add a diffuser to the sides past the exhaust tips? I looks a bit odd to me without the side of the diffusers.

 

Go back to post #4 to see what muffler covers extending to the sides might look like.

 

Not sure how I missed that. Yeah that would be more my style. I'll keep this in mind when I'm ready to purchase this. Still have a few other mods that hold priority over this at the moment. Excited to see you're in Arizona as well!
