If you going to change the hubs fit LCR/S3/TT/Octavia/MK4 R32 ones. This will give you a better suspension set up.
You will have to change the ball joints, wish bones, strutts and ARB but you will have better handling
But to answer your question, yes MK4 Golf GTI ones will fit your car
Cheers for the reply willie, i only need a passenger side one as ive got a problem with the passenger side hub, its a long story but for some reason the garage who did my wheel bearing (got the wheel bearing replaced cause of slight movement of play in wheel when i shook it) said they had so many problems with fitting the new bearing and they said the hub might need replacing (they had to do a alot of work to get the new one to fit, there is still like a mm of play when i rock the wheel at 12 and 6oclock position on the wheel), so i can get a whole hub for £25 off a mk4 golf gti turbo.
