How to get a good speed and good pickup for RX-Z? For now, my top speed is just 140km/h and looking forward to make my RX-Z top speed reaching the ‘km/h’ label (about 220km/h). Is it possible? What other modification do I need to do? Also, the top RPM is just 9000+. I have looked at one of the RX-Z reaching far beyond the 12000+ RPM. How do they do it? Comment if you know how!
