Building a complete under aero tray and diffuser :)

Planning on building a complete under tray from the front bumper to the rear. Then trying for a diffuser. First thing I need to know is what do you guys think a good thickness on aluminium should be? Does anyone know the thickness of a Z1 under tray would be? I have plate that's 0.10-0.11 thick but its really stiff and seems to be over kill. Was thinking about 0.05 thick. Any ideas?

Read my mind...subscribed.

I'm planning to change my oil this weekend. If no one else gets you the measurement before them ill get it for you.

Only suggestion I have is maybe to consider a material called Dibond instead of the aluminum sheet. I know a lot of AutoX guys use dibond for there front splitters.

Thought about it but since it won't carry load like a splitter would I think regular should be ok.

I did find this though...build full under tray and diffuser - MY350Z.COM Forums

I have some reading to do with angles and all that.

Just for clarification...that is NOT a Z1 product (I know bc I worked there). It is actually a part from ZSPEED Performance (Joe Allison). Just want to make sure credit is given where credit is due.

Check out TimeAttackForums.com. These guys are hard core track guys who build a fair amount of their own aero parts. Dybond, thin SS or aluminum, plywood....they use it all. There was a guy who built an entire aluminum undertray setup like this for his Evo. Front to back it was 5~6 pieces with an integrated diffuser.

Dybond is an awesome product. But be careful around the exhaust sections. Dybond would be OK for the sides, but I would not use it to cover the trans tunnel or close to the diff/exhaust.

You will need to cool the transmission and diff. In for pics!
