Thanks again everyone. I also recently installed MPerformance HAS and this has also improved my ride quality. I adjusted my suspension a bit too in order to make the fender gaps more even. Corner balancing coming this Friday.

The ride quality is a lot better overall - much more suited for daily driving. I no longer have fears of busting my tiny tires on those 20 inch wheels. I also prefer the 437 design, but that is of course subjective.
And the best thing - it takes me like a minute to clean each wheel, versus 5 compared to 666.
