What is best for Neg Camber?
the bruce:
Folks, I'm still confused. :laugh:
I have the S3 arms on my car and S3 swivels/hubs ready to fit.
Whiteline ALK is coming soon.
But I need some additional camber as well, - 2°20' should match
coming semi slicks. So what to do now?
- fitting S3 hubs and replacing the S3 arms with TT ones?
- fitting complete TT arms and hubs?
- fitting S3 hubs and forget all the camber issues?

:smiley: As you may have seen, everybody is confused. :surprised:
I had the TT arms on my agenda and today I saw that they do not fit the same for everybody :smiley:.
For fuscobal, with GTI hubs, the TT arms are working fine (as intended). Camber is -2.3'.
For danishmkvgti, this S3 hubs, the TT arms can not be installed correctly but they are ok the way they are.
I would definitely get the TT arms (and I will very soon). Since you bought the S3 hubs, I would use those. If I were you I would also sell the S3 arms.
Camber is crucial on the circuit and all cars have negative camber (more or less aggressive). Please look at WTCC pictures, Formula 1 pictures, Formula 3 pictures tc.
the bruce:
No doubt the proper camber is crucial on track. :wink:
My Federal 595 RS-R will benefit from at least 2° and I will go for Direzza 03G
later this year, so camber gets even more important.
I would gladly change some other parts if necessary, but replacing the steering
rack will be a bit too expensive.

If you want more négative camber, TT arms are definitely the way to go.
According to my measurement they should (I have to check it on the car when fitted) add from -1° to -1°45' (-1,75°) to your actual négative camber value, dépanding on how you set the ball joint up (thanks to the oblong fixing holes)
So, if you had 1° of negative camber you will end up from 2° to 2°45' of negative camber.
Then, or you can stick with OEM GTI swivel or go for S3 one (a bit lighter and may be stronger) (TT one don't seems to fit)
If you keep GTI swivel, you will be able to fit the ball joint under the TT arm as it has been designed and fitted on TT.
If you use S3 swivel, as it is more bulky than GTI one, you will have to fit the ball joint over the TT arm giving enough clearance to the swivel to turn around his vertical axle.
Note:
Ball joint fitted under or over the arm doesn't alter the geometry. What matter is not the postion of the arm itself but rather the position of the axle determinate by the fixing point of the arm to the subframe and the swivel ball joint.
TT swivel have a different fixing point which allow this clearance.

I would go for the TT hubs and the TT arms. This will give you the best camber and also the best wishbone angle.
