13" or 15" in my case how much different?
Finally looking for wheels for my car. R1 powered Seven. Caterham sized chassis and care has been taken to save weight, so should be quite light.
Looking for wheels to fit Miata(MX-5) based suspension (4x100 with 40mm offset being ideal).
In 13" I have found the Compomotive CXR's to be appealing. at 10.3 lbs, with an appropriate tire (Toyo R888 at 19.1 lbs) total is 29.4.
In 15" Looking at Motegi Traklite 2 at 10.0 lbs, with an appropriate tire (Toyo R888 at 19.8 lbs) total of 29.8.
or in black..
Unfortunately getting the Compomotive in the states is not easy, and the offset is not ideal (30mm max I think).
Lighter than these I can't afford so....opinions?
Specifically, how big an affect the .4 lbs per corner. (The 15" wheel combo would be .2 inches larger in radius). I understand it is not as
simple as all that, as it depends where on the wheel the mass is but any thoughts appreciated.
Thanks,
Brian

Speak to compomotive in the uk direct, they'll probably ship to the states or tell you of a dealer. They also have different castings for a wide
range of offsets, worth having a chat about your requirements, were very helpflu when I called last week.
No idea about the other wheels you mention I'm afraid.

Be careful to ensure that 13" will clear your hubs/calipers before you buy

As I also have a Miata, I am very familiar with that site, but thanks!
The wheels won't fit without some rework, I plan on using first generation MX-5 rotors on the rear, and the slightly larger 2nd generation
non-vented rear rotors on the front. Combined with low profile lightweight calipers,like Wilwood Powerlites.
