tuning will have alot on the way you drift. and on the steering wheel having a good initial tune will give you huge head start to learning. i found it helped with me heaps.
GTPLam. your claiming that you end up fishtailing and slamming into a wall. on your g27 are you using the clutch?? if the answers yes then i have a few tuning tips.
WARNING PERSONAL OPINIONS WRITEN BELOW! THESE ARE MY FINDINGS. THESE HAVE HELPED ME OUT ALOT AND MATCHES MY DRIFTING STYLE WONT ALWAYS HELP YOU. USE AT OWN RISK
Firstly LSD.
Initial Torque: 60
Acceleration: 60
Braking: 20
setting the initial torque to 60 i found to be really helpful as (in my opinion) it allows the drift to go on and on. the car wants to kick out. but i also found it to be really controllable. it seems to make the rear end much less responsive. or easier to manage. once you get better at controlling the car you can start to lower the initial torque.
acceleration io set to 60. you car make this number lower if your running large power, but you generally shouldnt need to touch it.
now braking sensitivity. 20??? yep. why? easy. if your using clutch, you have proberly found that when you change gears when its set to a high number, the car will try to grip and take off in the other direction. braking sensitivity determines how sensitive the car is when you back off the throttle. so setting it at a lower number will allow you to change gears or clutch, even just back off the throttle for a longer period of time.
suspension.
toe angles. easy. front. toe out gives you turn out response. toe in gives you turn in response! feel free to use large numbers if you have to. i find i get the drifting at a large angle, it starts to lose speed, oh s*** im now losing too much speed because i can bring it back. now try it again with a higher toe out. you might find the the car will understeer a little less on full lock as you have 1 wheel still gripping. it seems to work a little bit like extended steering lock. just remember you might have an awsum turn out, but turning in will be a b****.
rear toe. toe in equals drift exit speed. can be helpful if you just cant quite keep up. toe out will give you a much slower corner exit, but you will possibly find that you can hold much bigger drift angles.
spring rates. now this is BIG. the spring rate will be a major factor in how the car reacts with acceleration and deceleration. start with the front springs. find a number you like and leave the front springs set to that number. i suggest something under 10kg. start going higher and tracks like trial mountain and eiger norwand get REALLY tricky to drift. now set the rear to something similar. drift it. if you swap ends too quickly under power, lower the rear spring rate. if you find ur halfway through a corner back off just a little too much, raise the rear stiffness. keep trying the numbers untill you find that magic number that suits you.
gear ratios. completely up to you but heres what i think. keep them slightly lower. you dont generally need to do much more than 265km/h. generally munjis dont go much past 180km/h on comfort hards without major downforce. try to keep all separate gears over 1.000. falling below 1000 wil make the motor work harder to pull that particular gear. and feel free to change individual gears. maybe you like the gear ratios but you cant get that 1 large corner because you dont have the power to keep the wheels spinning round that bend. so bring that gear slightly closer. that corner is looking more achievable now!!!
Throttle control. your getting better. but it just doesnt feel right. chances are your not driving you car quite right. ever found an s bend with a straight in the middle, you like the gear your just fall short of the corner. take a look at your power range. this is pretty helpful. that is where you car makes its power. limiter bashing will infact slow your car down and "limit" its speed. but i bet if you let the car sit just off the redline with out it valve bouncing, you will gain a bit more speed. as start gaining speed whilst drifting slowly release the throttle trying to keep the revs at the same spot the whole time. the reason why you can continue to gain more speed whilst holding the same revs is because the spinning tyres are slowly catching grip. not enough to catch and make you swap ends or understeer, but enough to gain the necessary speed and really use that gear properly. chances are you will get through those tricky high speed corners better by backing off more.
