I need to know if this is gonna lower my box a little bit lower. I have 17x7's with 215/45/17 with Tanabe DF210's on it and its low but it doesn't scrape. If that makes sense to anyone. Will I get the lower effect that I am looking for with 205/40/17 tires instead? Does anyone out there have any pics?? Thanks in advance.

 

The 205 /40's are 5% smaller than the 215/45's. They will change the speedo reading 5% faster and be almost 1" smaller in diameter resulting in the car riding about 1/2 inch closer to the ground. Distance from the top of the tire to the fender will get about 1/2 inch bigger as well.
