(**UPDATED**) This is not a complete hardware kit. You need four 3x10mm grub screws to do both front and back anti-away bars, but the kit only comes with 2. You also need 8 ball cups. Your Car kit comes with 8 of these but 2 are used for the steering link so you have to buy more of these also, and AE only sells them with a complete set of ball cups for $10 Part# ASC91820.(**UPDATED**)
If you are using the jconcepts aluminum front camber link bulkhead (JCO2568-1) the included 2.5x6mm Button head screws will be too long. You will need to buy 2.5x4mm screws.
The hardware kit also comes with two retention collars one is black and one is blue. They seem to have the same dimensions with the exception of the black one having a slightly smaller inner diameter. Since the front uses smaller diameter bars it makes sense to put this one in the front, but I've seen youtube videos of people doing the opposite citing that it allows for less side to side play. I did not find this to be the case. No instructions to clarify this, and instructions provided in B6.1 manual does not specify.
(**Update**) You do only need 2 grub screws, because the front anti-sway bar attaches to the arms using the anti-roll bar link that is included in your car kit. This looks like a servo spacer. I adjusted my rating up 2 stars for this but still not 5 stars due to lack of instructions. I'm putting these on a T6.1 which has no instructions in the manual, and no instructions are included with the sway bars or hardware kit. I had to look in a b6.1 manual to find out about the bar link.
