first of all, you should not buy full-racing parts (Full-Custom Suspension, LSD) which
are not ideal for drifting. only the Full-Racing Transmission is good in all of the Full-Custom parts
you should not buy the Full-Custom LSD, it destroys the balance of your car. instead, buy the 1.5way LSD.
next, you should not use different tires (Front-Sports Rear-Normal) use Sports Tires on both
next, your damper level is too high. if you are using a Full-Custom Suspension, replace it with a Sports or Semi-Racing. try this damper level setting (Front-3 Rear-5) or (Front-4 Rear-6)
you do not have engine balancing and sports brakes?? they are some of the most essential parts for drifting. i know it is quite expensive but trust me, you will not regret buying them
next, you should buy these upgrades:
Single plate clutch
Sports Flywheel
Carbon Driveshaft
keep the Turbo and Intercooler at stage 1. install a sports or semi-racing muffler if you want to
finally, reduce the weight of your car to just Stage 1, don't go beyond. you will have weight-shifting problems if you buy the Stage 2 or 3.
got all of it?? to summarize it, just look at my thread, find the title YOU want DRIFT?? look no further
