yea, i'm guessing bbs too, have you seen the prices on them? its near 900 each OR you can get rota formula mesh's for less then 900 for 4 lol
yeah they are absolutely ridiculously expensive here are the s203's just to give you a point of reference. http://www.gruppe-s.com/Sti/sti_sub.htm and yeah, I'm pretty sure they are bbs
Rotas look just like them... http://www.subydude.com/osc/product_info.php/cPath/220_21_158/products_id/262
I probably would have gotten the formula mesh if they were offered in 17" sizes. I think they look soo sick in dark grey
+10000000000 on that. i was debating this issue at the install day today! but because i love them so much, i might just get the 18"..
