i finally have enough money for transport to mandalika and i am still on my old michelin PS5 tyres. the brake pad is running low. i also adjust the Coilover ST from @art_tembox7 making tighter preload and compress is 2cm more to help my front end from bouncing too much.
i face abit of traffic but it wasn’t slowing me down that much. i have also remove mid muffler. i will remove the factory resonator next. this is done at bimmerfest trackday… i am leaving my car in lombok to save cost until the next trackday. i will try wider hankook RS4 next.
compared to my 2nd attempt, the biggest improvement i have is my driving on turn 1-10-16. i took abit more risk and try to avoid making the rear step out no matter how tempting it is… my first 2 times in mandalika, i was having too much fun going sideway. this time just by tidying up my driving, i gain much more and cutting 3 seconds of my previous PB (Personal Best)
till next time and GBU all ❤️
