Are the R&L aftermarket ones?

The reason I started the thread is I have a set of S3 hubs and am considering fitting them with the tt bottom arms.

I have heard the TT hubs widen the Track even further???

I'm fairly sure it'll be machined alloy, rather than cast - so I can't see any strength issues. Certainly better than cast pig iron we have.

They are cast alloy but much chunkier than the iron items.

The hub carriers are double chunky, its been causing me problems as the lugs that the brakes attach to are probably twice as thick as the standard ones. So depending on the application some of the bigger caliper upgrades bolt on from the other direction and therfore need a different offset.

Thanks to Stokey for the loan of one

TBH talk of these things failing is unfounded its a substantial casting which is obviously reinforced in certain areas with the actual bearing carrier being iron, theres a small gasket to prevent dissimilar metal corrosion but the whole thing just looks right and weighs substantially less than the GTi ones

Sorry, R&L means Right&Left!!!

I also heard that TT arms one's widen the track, but I'm not sure about it.

I can't imagine either if these castings failing either !!

A guy on here (VenetianS3) has stated that a hub failure ended the life of his ED30. Maybe he meant the bearing failed ??

Should be about half the weight give or take.. I would expect about 5 - 7kg for the pair..

S3 hubs are enormous :jumping:

ETKA:

S3 parts number : 3C0 407 253 F
                              3C0 407 254 F

TT parts number : 8J0 407 253 D
                             8J0 407 254 D

Does commun numbers (407 253/254) means that parts are the same?

Any influence on the roll center as compared to the GTI ones ?

S3 ??

No.

They're the same as Passat, Superb, Sharan 2011.
So not for true sports applications only.

The TT hubs do rise the center of roll.



BTW,
the aluminium arms are all forged for the highest strengh,
the aluminum hubs are made in special combined cast/forge
procedure called ''Cobapress'':

Yeah but the TT hubs don't work on our cars without touching other components either wich would prove quite expensive. I suppose TT lower arms + S3 hubs will keep a similar roll center as with GTI hubs but the weight should be nice. JonnyC said something about 5-7kg but I didn't understand if he meant the weight of a pair of S3 hubs or the difference in weight between GTI and S3 hubs. If it's the difference then I find it huge !
