New 07 Yaris S need advice on 18's and springs

[jookybanana]

i have 18x7.5 and 215/35/18 rubber, droped on df210 springs and it rubbed slightly for the first couple of days, but now its gone, it will wear in, and i checked the fender liner and its looks fine, no holes or heavily worn out parts

if you go 18x7 it probably wont make a difference since you will still run 215/35 tires, unless you have 205 tires, but i havent seen any for 18" except for toyo t1-r

i'm not sure if weight (big guys) would make a big difference, but i still daily on 18" and drive lots of people and it hasnt been a problem, i think any lower than spring drop there will be some problems, like coil-overs low
