Nice find. You could always buy one spindle from a crashed passat and test out that theory. I have found some one Car-parts.com for $40 per spindle.

Grand Am APR cars have Passat OE Aluminum Upright?

So the B6/B7 Passat suspension geometry is the same as the Mk5/6 Golf? It would make sense that the brake rotors are the same diameter and width on the B7 as the MK6 GTI/TDI. That would open up VR6 and 4motion brake swaps. The VR6 has 12.5" fronts, and the 4motion has 13.1" R32 brakes.

Some years ago when I suggested to use the S3/Passat swivels and control
arms some guys said they possibly wouldn't be strong enough. :bonk:
Today we know they are even stronger. The heavier S3, Passat R36 and
Sharan come with these from factory and even race cars use them. :smoking:
Aluminium weaker than steel? Yes, if both are same size. But these aluminium
parts are bulkier and they are forged > at least as strong as cast steel.

Pressed forged keep in mind, Hot forging would not be consistent with the material because of Aluminum's melting point being low. More mass, reduced weight, all benefits in racing circuit. The cast up-rights have more air pockets because of the "casting" process, thus creating small gaps in metal, when exposed to extreme stress i.e. road racing more opportunity for failure. All metal has a breaking point, just like bending a paper clip back and forth, soon it will become 2 pcs. :thumbup:

These get rave reviews from MKV guys. kashak has them I believe.

Aluminum it's actually stronger than many steels in certain alloys and is heavily used in vehicle structure and suspension. Aluminum versus cast steel? I'll take aluminum.......lighter, as strong or stronger.......just more costly.

So this is to be used with the stock LCA ... 560 $ for one or for a pair... Hard to tell how much camber gain... Interesting though.
Also, I think, please don't quote me on this, that these would not help with the clearance of the fender, since it would only push the bottom of the wheel out wards.

Well, I have done it boys and girls.
I have gone the aluminium way for both Spindles and LCA.
They are not fitted to the car, but I will give a full report when done.
Can't wait. Also, this will be working together with the Boxter caliper setup.

Hot damn, I'm going down this route after my xenon headlight retrofit. I already bought the brackets from Apikol after discussing with him my concerns of possible fitment issues (other than different length bolts for the carrier to spindle attachment). Keep us informed!:thumbup:
Did you go the junkyard route? Looking on car-part.com I think I can get all four components for ~$250, but I haven't seen anything definitive over whether the Passat ball joint is the same as the Golf.

Is it possible that during the install you could compare the weights of the stamped steel vs. aluminum LCA? I wonder if there is much weight savings there.

Tyrol Mike already did all the work :
The weigh-in:
Stock Lower
Passat Lower
TT Lower (.25lbs heavier than Passat)
Stock Spindle
Passat Spindle
Face off:
The total weight savings is almost seven pounds per corner, with no tradeoffs. Win.eace: :heart:

The only thing different is the fact that the mk6 gti has stamped LCAs which are still heavier than the aluminum ones, but lighter than the cast iron ones... but these stamped things are also bendable...not confidence inspiring...

Yeah, I had seen the cast iron vs aluminum weights from Mike. I was just curious about the stamped vs. aluminum weights.
Thanks for the reminder though.

TyrolMike only measured the Cast Iron LCAs not the stamped steal ones. I believe the MK6 Golf R's still come with the iron ones.
I replaced my LCAs with TT ones. I'll try to pull the stock ones out of the garage tonight and measure how much they weigh with the Ball joint on it. Also the Passat balljoint is the same as the golf. Its the TT ones that are different but the TT ones will press just fine into the golf housing if retrofitting the TT arms onto our platform like I did.
