Sweet, will have to hit Subaru up for the sleeves I guess, bet theres no STIs at pick a part .
Im not a big fan of floppy suspension!, it just makes me laugh that one car manufacturer can make 2 control arms and 1 ball joint and they need a sleeve to fit one and not the other, were you not thinking the day you designed the alloy one????
Ninja edit: I cant see how the Z shaped end links are likely to shear off bolts any less than the dogbone ones (whiteline actually quotes them both excluding sti alloy arms) they will still sit at the same ghastly angle with only one side of the bolt supported!!!! I think Ill get the ones with spherical bearings in at least they are designed to angle and adjust.
