Richard JamesI recently got a full 4×100 syncro setup from Canada. I need 5 lug in the rear and desperately need help in trying to figure out if I can Just fit 5×100 hubs onto the 4×100 control arms? Will this work?
Any help is greatly appreciated I have no resources for this over here.
Thank you!
Houseychris S will probably correct me, but i i recall, the Front VR6 5×100 hubs can be used on the rear on the syncro to make it 5×100 
Chris SYes they can, I swapped 5 stud rear hubs out of my VR6 Wide Track axle conversion & pushed in the rear 4 stud MK 2 hubs, you will need new wheel bearings as you destroy them when removing the original hubs.
or this may be an alternative idea

Richard JamesOkay great thank you guys! Thanks for not getting mad at the newbie here. So will American front hubs work? Also is the rear track different widths with 4×100 and 5×100 control arms? Its made 577whp so I am afraid to run adapters with that much power, but I may be conservative. Thanks again you guys are saving me.
Chris SWhen you say you bought a Syncro set up from Canada, I take it that it is a Passat 35i Syncro drive train?
The Golf & Passat rear track is the same width, apart from the Golf 3 VR6 Syncro which is 20mm wider.
With 577 WHP I would strongly suggest that you convert your Syncro system 4 Motion Haldex & with a suitable gearbox & haldex adapted rear axle,
These links will be of help, especially the last one!

Richard JamesCorrect it is out of a passat. I almost bought a wrecked R before I bought this setup but thought and researched to find this is clearly easier to install.
As for the power capibilities it has peloquins installed front and bacl and this gear set:http://aptuning.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=396&category_id=630&option=com_virtuemart&Itemid=14 With any luck it will hold for a few years. Does the transfer case share fluid with the trans? and if so how much?
Great thank for the links, I am going to wait till I blow something just cause there is thousands alone in the trans with gears and LSD!
Chris SYes 2.4 liters
Here is everything you might want to know about the drive train
