Challenge wheels for street use?

I love the look of my R112 JCW wheels, but I’m looking for something lighter (maybe wider too) that still clears the JCW brakes for use with my Summer/AutoX tires. Does anyone have any experience with the genuine Challenge R112 7.5 x 17 - ET38 wheels used in the challenge race series? Is it (36110432960) any lighter than the 36116784130? Will I also need the challenge wheel bolts? Are there any issues with using this wheel on the street with street tires?

Thank you in advance for your help.

Interesting. Anyone know what these weigh by themselves?

The consumer version 17x7 (R112) [p/n 36116784130] @ 48mm offset are: 9.4kg
The Challenge Cup race car 17x7.5 (R112) [p/n 36110432960] @ 38mm offset are 9.5kg

For the price, an aftermarket set of custom spec'd wheels could be the better economical choice; especially the weight...

Great link, thanks.
Have seen those wheels in SCCA Spec Miata and liked them.
Certainly worth a look.
