15mm JR Wheel Spacers & 10 Ball Seat Bolts M14x1.5 40mm - Porsche 911 991 (2011-2020)
Supplier stock
On the Porsche 911 991 (2011-2020) a 15 mm spacer moves each wheel 15 mm outwards: the track width of the axle grows by 30 mm and the effective wheel offset (ET) drops by 15 mm. The standard bolt is then too short. The kit comes with the 40 mm bolts, so you do not have to work out the length yourself.
For competition cars onlyThis product is not homologated for use on public roads. It is fitted to competition cars used on circuit, in rally or in drift.
Check your original wheel bolt before ordering
The new bolt needs the same seat as the original one and has to be longer than it by the thickness of the spacer. On factory wheels, Porsche uses an R14 ball seat (28 mm sphere), and the original length depends on the model and the wheel. Aftermarket wheels may need a different seat, and a seat with the wrong radius only touches the wheel on a thin ring and can work loose. Measure your original bolt and compare it with the length in this kit. If it does not match, if the wheel is not the factory one, or if you are not sure, send us a photo of the original bolt and the wheel brand before ordering.
