Don't forget about the center bore sizes: front - 70mm, rear - 64mm

 

would these specs work?

17x8+53 114.3 5 hole and 17x9+53 114.3 5h

what are good sites to look for wheels?

 

From the Wheel Fitment Guide stickie ^^^

>>>
Based on successes and failures from many S2000 owners, we can use an offset calculator to figure out what other offsets and tires will work. These are minimum recommended offsets. You can use a higher offset if you want, and you will get additional fender clearance.

For the front:
205 tires: +43 offset minimum (6.5

 

so according to that, they will work.

thanks ZDan.
