Message: <blockquote data-quote="MrNismo" data-source="post: 587942" data-attributes="member: 13">Why do you need harder spring to drift?As we all know, an overall soft suspension (note that for soft I mean soft spring rate and soft damper bump/rebound) will have a natural tendency to induce understeer, so does a hard front soft rear setup. Of course you can compensate the initial understeer by using cheap rear tyres or methods like handbrake/clutch kick. However, serious drifting isn't about initiation only, it's about controlling and linking. For a soft suspension, too much weight will be thrown around during transition, the outside tyre will probably take a lot of load, and it makes life worse on a non lsd car as it won't push the car further or hold the drift longer. Not only that, the suspension travel will affect the geometry changes badly, which further worsens the control of the car. Not to mention the car might topple during sudden drift at high speed.Harder spring doesn't really mean bad handling/recovery. It's how you suit the damper rates to the condition of the track. D1 cars use hard suspension for that reason, they can't go with the 2nd option. However, it has little to do with tyres. Grippy tyres is always harder to control as it bites. It makes initiation harder and the car will snap back easily if the setup is not right. But we are talking about D1 cars and we all know D1 cars have lots of power and torque under their hood. If they use ciplak tyres like us, their cars probably won't move and will still be wheel spining on the spot on 5th gear. D1 is judged on speed. Obviously cheap tyres is not gonna give any. Hence you see performance tyres like AD07, RE-01R...Talk of power of D1 cars, another reason for stiffer suspension. Have you ever seen a purpose-built dragster? The rear squat as it accelerates with the front wheel almost lifting off. If D1 cars have soft suspension that will cause the rear to squat too much when accelerating out of a corner, that means the steering will have less input and the front will be less pointy. The result, understeer, or spin.Don't get me wrong. I didn't mean that you can't drift a car with a soft suspension. It's ok to have fun, just like people talking about FF drift. However, if you're serious, think of getting a suspension with reasonable hardness. You'll get more fun out of it.</blockquote>
