They might be 547R. C97 has a step lip, and from the pictures looks like a reverse lip.

Congrats on the new wheels!

 

There is a Gallardo around Akron with orange lip (Body) and black center and it looks amazing.

I would search on the tire size problem. There have been a number of 996tt's with a destroyed diff from this tire sizing.

IMO just pull the front drive shaft and go 2wd (fun) till the rears are toast then get the proper size.

Ok, I'll check it out. The rear lip is huge, the fronts not so much

 

Those wheels are sweet!

 

My friend has an orange Gallardo Superleggera in Akron, but it has grey wheels. I haven't seen the one you're talking about.

 

Yep, those wheels are perfect for the exterior color of your car.
Sweet
