The Time Attack series (cscs.ca) I use to perform in changed their rules for 2014 !!
for the worst.

For years they were allowing full aero mods (splitter/underbody/diffuser) with no restriction.
Now that diffuser/underbody is illegal as well as the splitter I had before because it goes pass the middle of the front tire.

This would put in me in Unlimited !!!
Not cool !!!

I'm lucky I didn't plan to finish first at the end because I will have no chance against those 500whp++ setup !

Damn that looks sweet dude! Let's just hope it helps out with all the effort put into it. What angle did you use for the diffuser?

thanks !

I doubt it will really show anything for the relatively slow track where CSCS goes. I'm mostly building the Z for 2015 on the fast track but yeah it should look badass and intimidating !!

As for the angle on the diffuser ?
- The diffuser box is 51''wide 40'' long at 20deg with the stock suspension the diffuser is set at 3 3/4'' to the ground.
- The muffler section has a curved bottom plate that start at about 5deg for like 10inch due to the exhaust then start curving up and
- The 2 middle section lower plate is set at 10deg

then

the side diffuser/winglet are mostly slowly progressive.

the black material is Alupanel in 3mm, a 4'x8' sheet weight 24 lbs

depending on how everything goes. those panel will be used to make a lighter version panel in Carbon Fiber/ Fiberglass later on.

the diffuser setup picture on the #287 post weight at 26 lbs 12oz which include all bracket / rivnut / screw / rivets.

Well at least you know you've added 26.75 lbs. of downforce

FuTuRe is Z

I don't know how viable all those aero equipment is, the diffuser in theory should add downforce, however they may be overkill. Additionally we don't know how adverse the drag is to performance.

Megan370z

I would agree with you IF I was just making a diffuser alone, yeah it could be overkill and not provide much but drag wize , it would be less than stock.

I beg to differ .
Do you own research on this.
Lookup on those Time Attack forum and especially on the F1 forum that guys modify their street car like ours with those aero improvement.

on every occasion where guys were doing their testing with equipment to know the pressure difference with the underbody, the diffuser/flat bottom ALWAYS worked and provided hundreds pounds of downforce.

remember just a splitter alone can provide a ton of downforce by just having a very small pressure difference between the bottom and the top....

this is not a guess but calculated.

no I wont do any pressure test
why ?
because I know the drag will much lower than the crap underbody we have, also it will have the added downforce. this wont really give much of an advantage in the slow track but it will on the fast track, fast corner.

Its gonna be wide !!

Some more details on the kit Im making for future reference.
OEM Base wheel
Front = 8'' +43
Rear = 9'' +15

Project being build for the RPF1 10.5 +15 square in mind.

Front = 60mm wider each side (120mm total)
Rear = 19mm wider each side ( 38mm total and spacer of 20mm)

Width Front Outside wheel = 75'' 9/16 (+/- 1/8)
Width Rear Outside wheel = 75'' 7/16 (+/- 1/8)




I should be able to start making the first part mold of the rear right quarter panel tonight ! (about time !!!!)
I cant do anything else which the list is soo freaking long... because I cant remove that damn bumper skin/diffuser until the mold is made !

That wing is so ugly. Take it off and ship it to me. It would look so good on my car instead.
