New to forum so 1st post of my own checked for this. Wondering if anyone has tried a diy corrugated plastic belly pan on their Altima. I have a 98 has cai and vortex generators on roof, 5spd and tuned up with plugs gapped .010 over manufactures suggestion. 32mpg before tuneup trying some aerodynamic for better mpg. Planning on doing bellypan from front stock one to back bumper. Any thoughts appreciated. TIA.

I highly doubt anyone has tried making that for an Altima lol but you should definitely do it! It would be a custom job for sure, would you use plastic or sheet metal?

I actually have a sheet of corrugated plastic sheet. Its durable and light just since ive been back to work since its summer seasonal work, i havent had time to get it fabbed up. Pics and data week after i do.
