This is for a set of 20 new chrome lugs and locks for the Porsche wheels and model combinations listed. The ball seat is what contacts your wheel at up to 90ft.lbs of pressure per bolt. All of that pressure must be evenly distributed in each bolt seat pocket or it will eventually crack/fracture your wheels. We acquired someone else's lugs as shown for comparison. Those are extremely undersized mass produced bolts with the standard ball seat for VW wheels.
Wheel shops, impacts, and finishes:Passenger cars rarely specify more than 90ft.lbs(check your specs) of torque for the wheel fasteners. Most wheel shops run their air impact guns flat out at 150ft lbs. If you're a 'car guy' you need to either carry a basic torque wrench with you or keep a 'torque stick' with you that matches your vehicle's specs and then require every wheel shop to use it. While the impact gun can't usually break a wheel bolt the much higher clamping force has several problems. The higher torque prevents you from changing a flat tire by hand, affects shear forces, but mostly it just damages your wheel. Lots of 'good used wheels' out there with hairline cracks in the seats. To protect finished bolts like these you also want to get a 17mm "protective socket".
Verify that you have Porsche factory wheels as shown in the auction images. Wheel+model+year must match. Compare your wheels. Note the spacing, count the slots/spokes. Pull one of your lug bolts and compare. Installer must test fit bolts.
Ball seat vs cone seatSo many Porsche lug bolt auctions are selling the \ / shaped cone seat bolts. There is no such thing as a Porsche wheel with cone seats. Factory Porsche wheels are always ball seat. Never under any circumstances run cone style lugs in a ball shaped bolt pocket. The problem is it focuses all of the clamping force at one spot on your wheel which doesn't distribute the pressure evenly in the pocket. This is the other way that wheels get...
