168 wheels – Got them, now a few Q's?

[Ajogu]

I’ve been ebay hunting for the 4.8 wheels for yonks and finally got a spanking new set Should be coming from Germany in about 10 days. Btw the stealer wanted to charge me $7k for the wheels and tires

A few questions I forgot to ask before getting carried away at the ebay auction:

1. Do the wheels fit without the 4.8 wheel arches?
2. I had tire pressure sensors on the 132’s, can I somehow put them on the 168’s?
3. If I don’t put the tire pressure sensors, will there be some kind of error on the OBC?
4. Finally, I’m planning to get some non-OEM dustless brake pads to protect the 168’s, could that void my warranty?

Thanks in advance for the help.

They should fit fine. It looks better with wheel arches, gives a better stance.
