SF Bay area: saw a flush 510 with deep dish wheels

When I was at Infineon Raceway I spotted this little Datsun 510 on a set of deep dish rims!

The 510’s hood was rollerpainted and the interior was stripped to next to nothing.

Here you have a bit better view of the deep dished wheels:

Anyone got an idea what brand/model these SSR Longchamps XR4 lookalikes are?
