Just got my SB Spice 8'2" and I can't get any of my FCS2 fins sets to completely go in? This is a first for me? I have a huge quiver of FCS2 fins. Funny as I didn't have this problem w my buddies 8'8" Spice and we were able to demo a lot of fins to dial it in.
They are tight. I used Wd40 lithium grease spray for first insertion and a towel to push down on the fin.
I have had a real problem with my Starboard pro. The Fin boxes not in properly and cracking.
New boxes under warranty: same problem as you FCS 2 fins won't properly go in. I had another shop look at the repair job which had been done under warranty and they were not impressed, the boxes look used. On this board the deck pad started to disintegrate almost immediately as well.
No problems on my previous starboard with deck pad or fin boxes - the thing was bomb proof.
I now have an infinity New Deal - absolutely amazing. I really like it and the Futers Fin boxes appear to be a big upgrade from the FCS 2.
Have the same problem with a new Kalama sup,the fcs 2 rear quads would not go past 3/4 of the way in,no matter how hard I pushed,and was worried I might damage the board,but finally used a protective cloth and a mallet,they went in!.also I had to reverse the action to get them out! As there was no way they will come out by hand ! The same with the fin box !
There is aftermarketd FCS2 lever tool for installation and removal

This was a major reason I have stayed away from FCS2 .
Just seem like a lot of stress on everything if you had to lever or hammer Fins in n out. I'll stick to older style Starboard and Gearbox slot boxes
Update. I've lubed and lightly sanded a fin set. 2 out of 4 seated properly, 2 won't go any further without damaging board between the tabs in the fin box. Fin bottom is hitting board deck. I've contacted SB to see what they say.
