Hello I have a 2014 scion tc. just put on some Yokohama 235/45/18s and the offset is like 35 or so. I am trying to find out what lowering springs to put on my scion. Looking at eibach sportline or prokit. I like how the sportlines look since theyre a noticable drop. However I don't want any rubbing to occur. Do you think I'll be okay with the sportlines? Or go with the prokits

 

You'll be fine. I used to have Sportlines with my 19" TRD wheels and 235/35/19 tires. Never rubbed at all.

 

I have a 14 on S-techs with stock tires and wheels, never rubbed, they've been installed for about 15-16 months, and 25k miles. Ran stock tires, and stock size snow tires for reference.
