Actually I ran the same size splitter as you have made and ran it at Pukekohe with the usual wing for a lower downforce setup and had a scary lose of the front at turn 1 which is near flat in 6th! (Hankook Z214's notorious for no feedback letting go)
I honestly thought the suspension had broken it was so sudden.
Dasting, what improvement did you see using the high mounted front wing? Gotta say it's not the prettiest, so hoping it worked well for you in lap time gains haha!
Any of you guys who have built your own floor, I'm currently making some test composite sandwich panels and wondering what you see in terms of load deflection? With my first off sample, an 11mm (7/16”) thick 300mm (12") wide strip, I clamped it to the bench hanging off 500mm (20") and put 2.3kg (5lb ish) on the end and saw 17mm (11/16") of deflection. This was very lightweight as I will continue to build the skin thickness, but just wondering if anyone else had made similar measurements?In case anyone's interested this was 600g/m² (18oz) fiberglass skins either side of 10mm blue modeling foam (polystyrene), weight is about 2.7kg/m² (5lb/yrd²). Comparisons are being made with carbon skins and different core materials, will see how I get on.
Just curious if anything ever came of this. Didn't see anything in the other old composites thread. Am contemplating attempting a fiberglass/foam core sandwich for flat floor/diffuser. I do not have the time/money/patience for vacuum bagged CF, and am looking for cheap experimental alternatives to the dibond I have now, which is heavy and requires a lot of additional bracing for rigidity (I have to mount below the "frame rails" in my RX7 due to exhaust, trans, diff, and bellhousing clearance issues.) There are some shapes in the back I'd like to play with that rule out other flat/plate materials like alumalite.

I build CF panels for Military OEM C-17 Air Craft. I would go CF because the cost is lower than ever.
Remember that with a core, what ever side the load is on is the side you make sure its stronger. If you put weight on your laminate from the top, the top will most likely fail withe carbon skin buckling and over lapping itself and not the other side ripping the CF.
What I've figured after years of working with composites is that what ever the thickness of your composite CF/Core/CF is going to be as stiff (not as strong) at the same thickness of T6 Aluminum.

I just question whether its worth the price difference since I won't be vacuum bagging. Seems impossible to tell if you've got voids/unsaturated areas like you can with glass, which negates the whole purpose.

If you were vacuum bagging I'd say CF because you're already putting so much cost and time in that you might as well. If it's just a wet layup there's no chance of pulling enough resin out to make a massive difference in strength and weight, so might as well be FG. Do spring for epoxy resin, that will make more of a difference in strength in your case over polyester than the extra cost for CF material vs FG.
It turned black, and a lot more duct-ey, and fiberglass-ey, and lighter, but a failed roller lifter took out my motor a few weekends ago at Carolina Motorsports Park. It's been decommissioned again for a new motor and a diff rebuild
Rear Wing on my '91 car for the German Solo Championship
View from behind, You can see the two wing-profiles, mounted on aluminium recks. With aluminium endplates, the upper wing is adjustable.
Price approx 600Euro, made from Aluminium and Carbonfibre. The size is in compliance to the rules in the German Championship, that means that all aeroparts should not to be seem in the front projection plane.
After one year of driving with this wing I'll found that I will need (only a little bit!) more downforce on the front axle. I started the work on a splitter splitter these days and give fotos to this platform.
