i'm not sure, so far, into this set of door panels, i have about 30 hours of labor and about 200 in CF/epoxy/sandpaper. (i have gone through a TON, i started w/ 150 grit, then 200, 400,1000,1800,and lastly 2400 grit. i've still easily easily got another 10 hours between reassembly and finishing the rest of the door parts and drilling holes for the speaker setup. so for a group buy (if i get 5 for a group buy, it saves me alot as i can buy in bulk) i'm thinking 580 for both doors or 1100 for front and rear doors. (one real CF panel is about 800 bucks for an evo. 1500 for the set.) so i think its a very very fair price. and the ones that i've found online are ONE layer of CF, and aren't very structural. since this is over ur stock panels, its very sturdy and guarenteed fitment. i have to price it out after everything is said and done, but basically, it comes out to me making about minimum wage on these! i plan to charge 750 for the fronts after the group buy.
