Wondering what the results of less positive offset on a rim. AFAIK the RX330 has a 35mm positive offset. For argument sake, what happens with using a rim with 30mm (not sure they even make 30mm) of positive offset? Potential to rub the tire on the inner fender wall or suspension/braking components?



Or anyone know the range of offset allowed in an RX330?

 

Realistically, there probably wouldn't be much of an issue slightly decreasing wheel offset if your car's suspension has not been modified in any way. You mustn't increase the offset, though! If you get too low, I think you would run into an issue where the front tires may rub against the fender liner or the fender opening in tighter turns, but I haven't a clue how low that would have to be. Because the RX isn't a popular tuning/customization platform, it's very unlikely that the legwork has been done to define the limitations.

 

That would stick the wheel further out from the car by 5mm. Generally what I have found in my weird obsession with wheels is the caliper is the usual obstacle. The best thing is to test fit to be sure you will not have any problems. Or find confirmation on the Internet.
