8P sportback.

B4 aren't compatible with lowering springs. Get the B8 instead or wait till you can get them. The B4 won't last what they're supposed to with those springs.

Cheers

as in they won't fit ? or they are a good match ?

They'll fit but they'll wear out much sooner than normal. B8 will last as expected.

[nicsabers]

They'll fit but they'll wear out much sooner than normal. B8 will have the normal lifetime.

I have a non s-line so i was thinking this could be a slight upgrade, even if they last 1.5-2 years I will be happy, then for for b8's when they die.

[Shoduchi]

B4 are the same as stock. B6 are the same as sport suspension and B8 are for lowering springs.

I don't know how long they will last, it depends on the roads and miles you'll drive.

[Jeffchiz]

as above b4s are same as standard, i would use them with a 20mm drop but any lower then the b8's are the ones to use

[nicsabers]

On their web site they quite they are fine to use with a lowering spring of up to 40mm. I only drive from Nottingham to Hampshire on motorways so its not going to take a battering.

[Shoduchi]

Yeap, motorways should be fine for what you're after.
