lots of questions tonight

what do you guys think about an under-body pan made out of FRP?... home depot sells 0.090 inch panels for $30 or so... 20 pounds for 32 square feet

.090 FRP Wall Board 4FTx8FT White-MFTF12IXA480009600 at The Home Depot

I'm not sure that it would be ridged enough to do any good, it is normally intended to be bonded to a backing panel. I would think that aluminum would have a better flex characteristic and not be much heavier.

may be right... check out the second link i posted... laminated frp on plastic core structure... should have more rigidity and weighs the same

ChrisSlicks · 09-06-2011, 09:12 PM

Okay that's more like it, seems like it would be pretty rigid.

travisjb · 09-06-2011, 09:21 PM

Just found out that we can get the same stuff but with alum skin instead of frp... same weight but even stiffer and will have better heat / flame properties... you never know!... ordered three sheets from R&J sign supplies... we'll see what I can do with it

Cool!

travisjb · 09-06-2011, 09:25 PM

Yet another question then done for tonight haha

What fasteners do you guys recommend for the bottom of the car? I'm tearing through bolt heads on my splitter, as they contact the tarmac at 100mph, and imagine same will happen on undertray depending upon how aggressive I get with it

XwChriswX · 09-06-2011, 09:34 PM

Travis, how are you liking the Stillen front end? The more of it I see, (especially on Mike the Powdercoaters black Z) the more I like it... Just kinda unsure about the fitment issues and the 3 pieces...

It's great for me... better aero, more room for cooling, etc.

For a street car, I would hesitate to use it because of the three piece design... and I'm not very picky... having the extra seam was a mistake on Stillen's part, I'm afraid to say... I think they did it for shipping purposes, but would have been better to leave it as one piece

Even if blended, likely to show cracks there eventually

Hopefully you won't be contact the undertray bolts-- maybe just countersink them?

Even the aluminum stuff looks like it has a relatively low ignition temp. It would make me kinda nervous.

Hmm, I'm just thinking for eventually one day a fun track car, and with the intercooler in the front, it will definitely look better.

And yeah I think it was for shipping? But if a good body shop does it, you think it's worth it?

Drywall screws

<jk>

I would think about adding a thin sacrificial plastic/nylon strip, not as perfect aero wise but good at absorbing scrapes.

My body guy told me that he could try to hide / blend but it would eventually start to crack and that I ought to just go with it... that's what I did... for a track car, looks fine... overall, I think it looks better than stock

Hmmm... Damn. I really like it, and I'm wondering if with black, would it be harder to notice??

Maybe if Mike ever sells his, I can just pick it up cheap...
