The Reverie also use rivnuts.

ReDRuM That's a great idea my current side skirts don't impinge on the jack points. I'll see if it's necessary to bury them deeper like yours.

oldmansan I cut holes in my Reverie side sills to allow jacking up the car without having to pull the sills. I put Velcro on the jacking points and cut-down (smaller diameter) hockey pucks. The pucks stay in place which makes jacking the car easier. I use the rearward jacking point to jack up one side until I get the jack stands in place.

ReDRuM Thanks for that info. These will be similar but using foam core. Little thicker carbon fiber sandwiching the foam core. These will need to be sturdy since their going to be quite wide.

The Reverie side skirts use a honeycomb core with a veneer of carbon on the top and bottom.

jdawson I'm curious what you have in store for the front splitter. Are you integrating diffusers that channel air into the now-vented wheel wells? Are you going to vent the top of the fender arches?

Making the diffuser outer fins extend forward more is also of benefit... getting the leading edge in front of or even with the forward surface of the tire likely helps prevent turbulent air coming off the tire from corrupting airflow in the outermost channels of the diffuser.

I did some crude wool tuft testing using a stock Difflow diffuser and some cardboard modifications:

Question for you. Did you consider buying a more turnkey GT3 wide body kit, saving yourself the effort, and using a tested aero body style?



BTW: The last wind tunnel analysis I read on the Exige proved the rear diffusor outter most fins need to be at most 40mm off the ground for maximum effectiveness. Your's look too height, assuming that's your final ride height.
Yup. That would be too easy and boring. Without experimentation, there's no innovation. Personal preference on the lines.

We can also make copies and repair a quarter panel if need be .

The diffuser fins are within 40mm from the ground and will be lower still . Ride height is yet to be properly dropped.

I have the Reverie ones. They're a veneer of carbon top and bottom and then a honeycomb middle. Stupid light.

ReDRuM Yes , could match the deck , but that might create unnecessary drag. Aiming for a tad more function than form really. I reckon this will look the biz once it's in carbon fiber.
We've looked at multiple race oriented cars and we're mimicking the same lines.

That's some serious 935ish fender extension.

I know I'm being a backseat designer, but if you can bring the height of the extension aft of the wheel well to the same height and contour as the OEM rear deck - IMHO will give a more cohesive and less add-on look.

Nice work.

Rizzydee Do you have any front profile pictures...get an idea of the "flow"
09-10-2019 09:33 PM
ReDRuM The wheels are ReDRuM Race wheels. Zen 1.0 design. For my next set I might adjust the offset since I wanted to go a little wider and so here I'm using a 12 mm spacer. Here's a picture with the center caps

Yes, go big or go home philosophy.

No access to wind tunnel. If nothing else the sills look cool I think.

Gonna make some funky looking louvres over the front wheels...

Check out some videos on Youtube with exiges and elises in wind tunnels. Side sills don't appear to do anything besides get in the way of your feet.

TedR Make sure you have enough clearance from the top of the tire to the inside top of the fender/flare extension to accommodate full compression. It looks tight.
