You're probably right and in that case , is there any benefit in putting 19s on ?
Depends on weight My 19s are lighter than the 18" rays
20s will be heavy as hell.
There used to be lots of debate on here in the old days about 18s vs 19s vs 20 & the effect the weights have on the car. Not to mention how poorly some of the cheaper wheels are made, a few of us had had a PWC group
I'm sure i was the founder of the PWC
