anyone running this set up? any problems? is this a good fit for an r53?

 

Compared to OEM 16" wheels and tires

Your proposed wheel fits 1.7mm further from the inner suspension and pokes out 14.4mm further which is fine. The upper outer treads of the tires will be 5mm taller than OEM and stick out about 20mm more which fits OEM suspension but might be close to rubbing under load for a lowered suspension.

So yes it fits with OEM suspension.

The most common plus size fitment for 16" wheels is 205/50-16.
