G-games 18x7.5 43 offset with 5X114.3/100 bolt pattern...will I have any problems with this on a tC with no drop? Sorry for the newbie question.

 

you could run that with an s-tech drop with no problems. Go for it.

 

You should be aiiight. Your rims will still be tucked in the wheel wells since stock is +45. (Even though you're getting 18s.) Personally, if you want the more flushed look, you should be looking at rims in the +38 - +33 offset range.

 

spacers will work too. You're ideally going to want a 10mm up front and a 15mm out back, but alas, i've yet to see a 10mm spacer for us

 

...Ill need spacers

 

you won't "need" them but it will change the look. the higher the positive offset the more they will look "tucked under" your car. the lower the offset, the more "flush they will look against the fender.
