V MAX coilovers and s line springs vag compatibility

Hi all
Just got some used v-max coilovers from fleebay
So will be getting these fitted soon to my a3 as the front has still not bedded in after a month of s line springs
thinking of a 45mm drop...or should i still wait for the springs to bed in???
Does anybody know if the s line springs are compatible with the seat leon mk II?or the v max
It is a sport reference which I believe has a 15mm factory drop...please correct if i am wrong i have forgotten most of the info on seats since the mrs has started to use the car

I guess I was better off posting this on seat-cupra.net

thought maybe members on here here had good vag knowledge
