Help im confused !!!!

[reckord]

Was about to by ball joints for my hdi 3 door on a 1999 v reg from euro carparts .expecting 16mm they are sayin the system says my registration is coming up as 18mm
Do i go ahead and expect these to fit ?
Obviously im thinking 18mm is for gti6 after seeing so many people sell hub knuckles as upgrades when breaking a gti6 .

[cully]

my Gti6 has 16mm
measure them to be sure

By phase 3 they should all be 18mm, but people change hubs etc so as cully says, best to measure them. Or if possible buy both and take back the ones you don't need.

I changed mine on my XS the part come up with 16mm but I new that wasn't the same looking at it, so I took the 18mm and it fitted They don't always get it rite . Best thing to do is take the old one off and take it in the shop with you.

I think im gonna buy em both then and take one bk
Thanks for the info
