I love this first picture... the stance to me is amazing. I guess its more so when you built it, but its just damn sexy. As a side note its a 3/4 roller with steering lol. All i have to do is mount the rear tires on the wheels and get someone to push me around!

still a ton of work left, but i felt i should post these pictures as i finally have a full roller plus steering. I still have a bunch of work to do with the rear diff, but more picture of the rear will come as i wrap it up..

The car really can fly... for those who were asking how i get it off the table...


bottom view of the header


flat bottom = good air flow. the rear will have a diffuser.


another shot from the bottom as i was praying the straps holding it up wouldnt snap


Underside of the front suspension box. Needs a few more welds. already have a carbon fiber section of flooring for it that will be installed after paint.


Measured from the ground up


again measured from the floor to top of roll bar. I made it higher then needed for the extra protection in the event of a rollover. Further below is a pic of me sitting in it for reference. The pictures just dont do justice as to how low this thing is.


This is why i went with a 16ga steel floor instead of aluminum..


front and rear suspension boxes have higher ground clearance.


completed front end suspension. once i get corner weights the R6 shocks will get new springs.


Just a side shot as a full roller


Here is a suspension shot to see how it works. First picture is at right height and second is the suspension when it is in compression. Note the movement of the shock, triangle, and entire suspension



This is at ride height to show how tall the car is... the tires are 24.5in tall and they stand higher then the frame!




Standing next to my art work...so proud. im 6ft for reference


Me sitting and loving it

Congrats Jerry, you must be pumped. looks awesome aswell.

I remember when I sat my car on its wheels, I was excited and had not clue how much work was around the corner. I found that making a checklist was the only way to track progress and know what was left.

keep on givin er

Thanks Andrew. I just started a checklist and I do have a ton left to finish and unfortunately its the more expensive part of the build for me. I'm just glad that is a more complete roller with with the engine all mounted/plumbed, steering is done, seats are close to complete, paddle shifters are fabed, ect...

Although there is a lot left, I'm glad that they are all smaller projects. With smaller projects you see constant progress and these are what keep me going.

That is so very cool! I envy you.

Good work. I like the look and the roll bars.

I'm one of those that think a roll bar or cage is there for a purpose and not just a look. I simply can't understand people that cut them down in height because they think it looks out of proportion. Upside or rolling around, god forbid, I want it to keep things as far from me as possible and of course not collapse.

Now a question about your front suspension. You basically have the top and bottom suspension pieces parallel. I've gotten used to seeing the top piece be at a little more of an angle than the bottom so that you get more into the camber curve quicker because let's face it, you have no more than about 3" of suspension compression at that ride height. So the question I have is how did you decide upon that particular configuration? Was it a previous car or did Wishbone sprinkle it with Holy Water and swear on a stack of bibles that was the optimum configuration?

As for the roll bars if you read back i decided on the height with safety in mind. I simply sat in the seat with my dad holding a piece of wood that sat on the front of the car and stretched over my head. I then had him raise it to clear 3" above my head with a helmet on. Simply measured at that height and calculated for the angle bend i needed in the roll bars. To be safe and avoid a wrinkle and for extra strength i used 0.120 wall. Although its not SCCA and other organization legal (because its two roll hoops) i still feel its stronger then most i have seen around. Im more then confident with it.

as for the front suspension, well the picture is a bit deceving because i dont have it at true ride height with the springs in. The front suspension is based largly off the miata setup. The arms are shorter so you dont see the angle as much as you see with longer arms. Off memory, when the lower is at 0* in ride height the upper is sitting at a -9* angle. At ride height i have -0.5* camber and at 3" bump i have 3-3.5* camber. This is actually measured values with an angle finder to verify... although its almost right on with my wishbone numbers. Look at the second picture of showing the suspension move and you will see it better.Most pictures are at full droop which show the UCA nearly 0* but the lower is not parallel as it is at a greater angle. The rear has the same camber curves.

Blue Devil. -Just looked over your build log for the first time, Nice Work! I love the set-up.
I can't see remotely hosted pics from work which is where I usually surf the forum during my lunch break but the pics show up at home. Congrats on a clever execution.

Let me know how the paint comes out!

The car looks GREAT, BD!

Keep it up,

Jerry, that's what I call sex on wheels!
Way to go, man.

Moti "sometimes Monti"...

Just a bit of an update as it has been a while. The past couple months have been crazy as i have been taking 16 credit hours (plus three 3 hour labs that count for nothing) as a Senior ME student as well as working 35 hours/week as a Research & Innovation Engineer for a Tier 1 supplier which has required me to travel way too much for a student.

I finally made a passenger seat, but i decided to mostly use fiberglass over carbon as the weight save in that area that will be covered by leather was not the best. Id rather save the carbon for areas that will be seen.

Next, i made the active spoiler that turned out amazing... pictures speak for themselves below. I made it from complete scratch.

And a few more. Ill post some pics of the actuator and computer board when i get some pics of them

(low whistle)

Very impressive! It came out great!

The wing looks great. Please post as much information as possible. I am getting ready to build a rear wing (and maybe front) for my car. I would really like to know how you decided on the airfoil shape and some more detail about the construction.

Thanks
Ken

Honestly i did a ton of searching and found a lot of debates on different SCCA and autocross sites. My profile originates from the predator unmanned aircraft and has been slightly modified to adapt to my build techniques. While a correct profile will create downforce through pressure changes from the flow over the top and bottom of the wing, most of the downforce will be generated by air redirected (or drag) over the top of the wing. I can load more pictures when i get to my home computer with all the pictures.

I still need to make it up your way to look at your project. I need some motivation to heat up my garage and get back to work! Once my wrist heals its back to the work/last year of college/car grind.

It's pretty cold right now to be working in a un-heated garage. This is a good time of year for planning. That's what I am doing. I have plans for the wings and possibly some power upgrades.

My car is actually at my buddy's place for tear down and paint right now. After a year of driving it in bare steel I need to get it cleaned up. It will be ready for the first track day of the year though in April.

Good luck, and please post whatever you have on the wing.
