SOrry guys, its solved in meantime. It should work the same as on F3s.. so lets see..

Hi Guys,
as i am not an owner of F3T, i would like to ask you if it is possible to change the rear shock?
My friend is bit heavy and we need to go for new front but also back would be great.. I just dont know how it is with that pillow back there....

thanx for tips
Martin
