Wheel brand question...Kgawa?

I have a 92 integra GS-r. I bought with a bunch of neat stuff on it, but not well maintained. The rims are throwing me. It has a signature on one of the spokes and looks like “Kgawa Racing Model S7” I can’t find these in any type of search. I am not 100% on the Kgawa as the writing is not clear on any of the rims. It does say Final Speed made in Japan on the inner part of the rim, between the spokes. They are 18 x 7 1/2 4 x 100.

The reason I ask is that one of the rims has a few cracks on the inside lip. The tire will not hold air because of that, so I was looking for a replacement. Anyone have any ideas? I can take pictures if needed. They are a silver finish.

Thanks

Russ

pics would help. any markings on the back of the rims?

final speed was a line from A-Tech, but the only S-7 i know of was the Stern Aguzze S-7 and i’ve only seen them in 15".

if you like the rims, you can have it repaired by a wheel repair shop, i would search the internet for one close to your location, otherwise there are a lot here in CA.
