Looks like some cars will fit 7s fine, and some will not.
The ones that don't, can be fixed with a small amount of rolling the fenders.
I have a car that shouldn't be modified and wimped out.
I got the 6s to be "on the safe side".
For a 205 cross section tire I really wanted 8s...
I went with 205/55/16. Absolutely perfect regarding diameter.
Look great on the 6s.
I purchased the Fuchs 911 copies from DR911 in 16X6
https://dr911.ca/product-category/wheels/16-x-6/After purchase many members said I was purchasing from a rip off artist.
DR911 came through fine for me. I am happy with my wheel purchase through them.
In thf future with that vendor I will try to use PayPal instead of direct CC.
If you're planning to change over to 5 lug, do your homework.
http://www.914world.com/bbs2/index.php?showtopic=105728PMB now has 914 front rotors with 5 lug and rear flanges that fit the 914 stubs with 5 lug (Uro brand).
