Of course just like my old Nissans my GSF will definitely be faster and faster in the future...

Believe it or not. I DO love to drive my son's G35S(with PSS10, Eibach) more then GSF when driving on mountain roads. Of course G35S has much much stiffer ride...

PS:
1. If you check tech category in GSF, you should find GSF score is very low in that category. I agree but I buy this car for driving performance. So it's totally fine for me. In addition, its brake score is not very good, either but I think it should be 8.0. Anyway. GSF is not so fast, so...
2. Of course GSF unit body is very stiff (maybe even stiffer than GT-R). Just the design of its shock absorbers is not so good because the design of shock absorbers are more like ART than ENGINEERING, I think. (Even GSF handling is very good but I still think M5 suspension is better than GSF and even GT-R!?! Similarly GSF is slow but its engine is better...)

PS: You may think GT-R handling is better than GSF. That's because GT-R suspension is stiffer. If I put Ohlins on my GSF, I think my GSF will be better... (even comparing with much stiffer Nismo)

Actually I don't like Car and Driver. I think their reviews are biased!?!
