16" alloys on an E46 sport?

[Mr_Sukebe]

About the only real complaint I have about my 330i sport is the ride quality (yeah, I know, should have noticed on the test drive). At the moment, my car is running the usual MV 18" wheels with typically low profile tyres.

I couldn't help but notice that 16" alloys are now quite cheap s/h and considered putting my MVs in the garage (for resale value), and stuffing some 16" wheels on with higher profile tyres.

Anyone else ever done that? Excluding the lower levels of grip from thinner tyres, is there anything else I should be aware of, e.g. spacers or similar?

Thanks for advising ref the brakes chaps, hadn't thought of that.
Just one inch difference is probably not going to make a massive amount of difference. Oh well, it was a thought.
