they take years to deliver k11 stuff, most probably cos they don't have any in stock and have to request em from the manufacturer.
first ordered a janspeed manifold, took bout a month.
then a bilstein streetline suspension kit with whiteline panhard rod, well over a month wait
finally ordered a janspeed system, after waiting a month i had enough and phoned matt humphris. he delivered it next day!
i highly recommend him first
