So the rx-7rr4 (corsair) used a 'new' technology for the shell and deemed it SNC (structure net composite).
On the new quantum II they use another 'new' technology called SCLC (SUPER COMPLEX LAMINATE CONSTRUCTION).
The astral and signet both use CLC, a dumbed down version of SCLC.
question is, which is lightest?
another question is in regards to their shape. arai used to proclaim that their different helmet models are designed around different head shapes. ie/ round vs. oval.....etc...
but with the 4 main models (rx7, quantum, astal, signet) which is which shape?
