What size wheels and tires are you running....looks awesome..

great car and awesome work. i am a body shop/restoration/welding instructor in new jersey. i would love to relocate to Florida. do you know of any names of state trade/ vocational schools i may be able to send a resume to? sick of the winter up here.

1st, this is my favorite mopar body style. However improving high speed aero and keeping the proper lines is got to be very tough. Your mock up maybe beneficial but as I suspect you already know, doesn't IMo enhance the visuals, which is probably not your #1 priority, but the car does look so nice. I don't disagree with your thinking, however, unless you plan on wind tunnel testing, it is all just an educated guess, that being said, I might give more difference to cosmetics, since it may not detract from your intents. I was on my ebody tossing around the idea of an at speed deploy able/foldable and/or air extended side skirts. Keeping it simple and reliable and non breakaway is my big hurdle, but would give streetable ground clearance, have little downside to appearance, but hopefully be effective when needed.

Short of recontouring your already gorgeous nearly finished cars sides into slabs, or adding FG covers, you have a tough hurdle here.

This you may not want to hear, but if this much concern is invested in aero on your car, I would ditch the OEM style spoiler and jump right to a swan mounted real multi element rear wing.

And the NC low speed wind tunnel runs about $450/hr.

JC,

Luckily I have a good racecar aero guy that is helping me concept and design. I will fine tune at A2, i.e. Diffuser plate sizes and shapes, wicker bills, etc. I consider it cheap insurance as apposed to flipping the car at Bonneville.

The stock rear spoiler has already been tested on this body style by someone else and the numbers are good for what I'm after. A long, flat deck spoiler would create equal down force with less drag, but not the look I'm after. I'll sacrifice drag for cosmetics, but not cosmetics for stability.

And on the same subject of cosmetics, I set the ride hieght higher than the current PT cars so the belly pan would be flat and sit right against the sub frame connectors and the bottom of the K frame. I set this to be a flat plane when i was building the car. So while it looks like the rockers are too low, if I were to scrape the rockers, I would have scraped the bottom of the car anyway without them.

I lowered the front K's lower control arm mounts and made the Watt's adjusted to pull the roll center down without having to slam the car to the ground.

I don't like them but if you make the bolt on and leave them a black color it would look okay.I know this car will be fast so it prolly needs them.Awesome build and I am glad to see more pics.

Bump to the top...
Any progress?

I mean this hidden jab in the most friendly and complimentary way, IMO the OP is a sharp, and talented perfectionist and craftsman, and will likely always be tweaking and pushing the envelope with his project, while many of us just watch in wonder.

on the diffusers, the rear of the rocker panel, would you want to have the tail end angle outwards to the tire sidewall, instead of ending the way you have it mocked.. Also, the rear of the 1/4 drop, would you want to taper that towards the center of the car? I'm not totally sure of the top speed concept, just throwing that out there. Would doing this make the car more apt to be "squirrely" at top speeds? And, what do you plan to do for cooling those ginormous brakes?

spoiler and bumper plugs are done and shipped to have molds made. Both will be available in fiberglass or carbon fiber. Bumper will have aluminum blocks on the back for attachment, and spoiler has an aluminum inner structure for attachment and strength. The spoiler will be available with a channel in the top to allow sliding in a 1/8" wide extension piece to make as much or as little downforce as you need.








The blue tape represents the channel that will be molded in the spoiler. You can slide in any height 1/8" plexi to make an extension. Through bolts from the back into the inner structure will secure it. You can make a contoured piece that looks stock and then slide it out for a taller one for track days. Once in awhile I actually have a good idea. I'm really liking this!




And the bumper... The valance is not bolted in the center which is why it looks pushed out. The bumper is laser straight!!

both parts...

Awesome

Nice

Thanks guys. I'll post up the production pieces as soon as I get them back.
