I just put a set of 16" 5 star alloys on as a set of winter wheels.
Not really taken with the look...
I had 15" Holies last year...and i loved them...car was soooo much nipper. The car was like a go kart. The car was lower...I thought they looked OK as well...but I sold them...
16" are not as much fun...and as they are runflats too...just as bumpy as my 18" 's...no lowering either
No extra acceleration either :(
So...I recommend 15"s...and may go back to them next year!
