These two cars were from the original parts maker Mekaru, a really neat 86 and wildly modified 180sx.
The 86 was so clean it was hard to see behind the reflection of the glass. What you can see is vast dimple die gussets everywhere. Mekaru are very skilled welders of all metals.
They seem to do some wild work with fibreglass aswell. The styling is not my cup of tea but its well finished.
Carbon and kevlar wasnt out of the question either.
