Do the blistein coilovers work on the non-brabus forfours (do they have the extra mounting point for the anti roll bar links?)
YES and
YES.
Why not combine having them fitted whilst your car is in for a service
as it could possibly save you money rather than 2 separate visits.
Or..you could try doing yourself...but you would need decent spring
compressors and maybe a garage airgun etc to undo the strut top
mounts and the top shock absorber nuts !
Shame in a way that you're round the other side of the world in Oz,
or I could've recommended a good place to have it all done over here.
For wheels...as a suggestion...see if anyone has Colt (2004-2008) alloys
for sale around your area. 16" or 17" diameter. CZT one's are not bad.
