Removing wheel
Information
Use suitable commercially available tools (wrench size 19 mm)! Never use an impact bolter to tighten the wheel bolts.
Before the wheel is placed on the wheel hub, re-grease the centring surface of the wheel hub (if required) as necessary with a very thin coat of Optimoly TA (aluminium paste).
The wheel bolt consists of two parts that are permanently joined together. Other wheel bolts must not be used.
Caution
Removing/fitting the wheels for vehicles with PCCB (Porsche Ceramic Composite Brake).
Risk of damage to the brake discs.
→ Use assembly aids (assembly pins) in order to exclude any possibility of heavy contact of the wheel with the brake disc. The assembly aids (2 assembly pins) are located in the luggage compartment.
Information
The assembly pins for removing / mounting the wheel for vehicles with PCCB can be ordered separately as a spare part. Part No.: 999 571 074 30.
– In the case of vehicles with PCCB (Porsche Ceramic Composite Brake), screw the two assembly aids (assembly pins), instead of two wheel bolts, into the wheel hub before removing the wheel. Only then remove the three remaining wheel bolts and remove the wheel carefully, without touching the brake discs.

NOTICE
Removing/fitting wheels
Risk of damage to (ceramic) brake discs
→ Use two assembly pins when removing and fitting the wheel.
→ Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.
Information
Use suitable commercially available tools (wrench size 19 mm)! Never use an impact bolter to tighten the wheel bolts.
Before the wheel is placed on the wheel hub, re-grease the centring surface of the wheel hub (if required) as necessary with a very thin coat of Optimoly TA (aluminium paste).

Information
The assembly pins for removing / mounting the wheel for vehicles with PCCB can be ordered separately as a spare part. Part No.: 999 571 074 30.
1. In the case of vehicles with PCCB (Porsche Ceramic Composite Brake), screw the two assembly aids (assembly pins) into the wheel hub before mounting the wheel.
Wheels with sensors for TPM: Before changing wheels (e.g. changing from summer to winter wheels), check that the wheels are compatible with the vehicle’s tyre pressure monitoring (TPM) system.

2. In the event of heavy soiling, clean the wheel bolts and the concavities in the wheel with a lint-free cloth.
3. Always apply a thin coat of Optimoly TA (aluminium paste) on the thread of the wheel bolts, on the shank and between the bolt head bearing surface and spherical cap ring (under the head) -arrows- . The spherical cap bearing surface -X- of the wheel bolts that face the wheel must not be greased.
Wheel bolt -A- - Spherical cap ring (permanently connected to the wheel bolt)
-X- - Spherical cap bearing surface facing the wheel (do not grease)
Information
Rework on wheel bolts is impermissible.
4. Always replace damaged wheel bolts.
This damage includes mechanical damage to the thread, the spherical cap and damage resulting from seizure of the bolt head bearing surface and spherical cap ring. It must be possible to rotate the spherical cap ring on the bolt shank and to move it in axial direction.
Information
Always observe the specified tightening torque. The tightening torque for securing wheels is contained in the document 4001TW. → 4001TW Tightening torques for front axle
5. Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening.
Silver wheel bolts (up to model year 2011) = 130 Nm (96 ftlb.). 160 Nm (118 ftlb.) also permitted retroactively.
Silver wheel bolts as of model year 2012 = 160 Nm (118 ftlb.).
Black wheel bolts = 160 Nm (118 ftlb.)

Holy crap Slow, that new 5-lug stuff sure looks complicated. Giving me a headache reading though that. Makes me glad I have CLs instead. Much easier.

LOL, You are probably right.
My brother drives by the front door of Orbit twice a day, so the most time I spend is handing brother the key and open e-mail ti see orbit invoice appear. My brother picked it up yesterday morning and dropped it off at the XPEL installer on his way to work.
Me just lazy, but if time is critical buy GT3 or CUP and let Orbit do it.
Never timed it. I should also blow out the rotor holes, but I always forget (Orbit forgets nothing). Makes a difference in brake feel, but now front have no more holes, so nog big difference I gues.
I will time it next time and call Guinness Book Of Records to witness. Or Rad, same thing.
I jack up one side of the time, just like 5 lug so it takes no longer then stuffing the truck brake between the brake pedal and the seat then it does on 5 lug to change 4 wheels.
