They run cars in over 50 different classes but last 2 events I ran under Road Registered Non-Logbooked over 2500cc. Even though I have a 1.6, the turbo bumps me to a different class for better parity. Turns out the other competitors in this class generally run better tyres and suspension setup so the stock SSS is not on par with the other cars. They should probably have different tiers within that class for cars road registered, non-logbooked with zero mods. Anyway, the SSS will run some Yokos next year and maybe some XYZ coilovers, that should lift its performance. Check out this video from Rd 8, my first outing at Ringwood Park, great track!
