But that the racing version of suprima with na engine

I think u can do that with preve manual and throw everything out in order to lightnen the car since the na engine is underpowered 

Ah..good insight and details!

Saw these quite sometime ago already

Suprima. Car is much quieter. Occasional low speed jerking is still there. Response is much better.

If you compare it with Bezza its nowhere near SS
but if you talk about after sales sadly to say that YES Proton still lot to achieve despite their CEO CFO announces desperatelly wanted to change the mindset of their staff to win back customer.

My own experience with SS how the Achiles tyre blown out of sudden in highway. I made call to their road assist and they faster can point me the solution.
Even they manage to get someone in higher level to call me and assured that the problem will be settle (This is on Sunday and all the nearest SC closed) , as a customer you feel relieve.
but then after that only the problem start arise -

cut the story short - They got all the SOP on the right place but the communication and the execution is badly miss out. I hope they learn the mistake and keep improving, I don't hate Proton coz they make a good car (good handling actually, probably also one of safest car) with a very reasonable price in  the market. If you think you can cope with the lousy after sales i think this is the best car you can own and FUN too.
