Team Associated 3.5mm Ballcups (14)

These work great. Used these with Lunsford 5.5 titanium ball studs. Virtually zero play and very free movement. Just because these look open on both sides, they do still have a top and a bottom. If you put them on with the cup inverted, they will pop on, but will be much harder to get on and may bind up in some of the movement, so make sure they are facing the correct way when you install them.

OEM ballcups for B7D. I replaced my OEM turnbuckles with titanium and wanted a spare set of ballcups to build it up with. These worked like a champ - OEM and plenty durable.

Losing a race due to popping a ball cup is the worst..... Upgrade to these 3.5mm ballcups and you'll never regret it.

The ball cups are extremely hard to put on and they don't even fit properly and they rub and are sticky on the ball stud. And due to them being hard to put on the pliers scratched the anodizing and plastic on my car.
