Alright yes there has been a ton of generalizations. I apologize, my main objection to most drift cars (although they arent used for trying to go as fast around a corner as possible so maybe I should dump why they need a proper suspension for going faster) is that they typically use spring rates and damping developed over in Japan, where they have perfectly smooth tracks and also the tendency for Japanese shocks to be complete junk on the lower end (Tein, Buddy Club, Megan Racing, etc.).
Good, but incredibly simple explanation of shock selections- <!-- m --><a class="postlink" href="http://farnorthracing.com/autocross_secrets6.html">http://farnorthracing.com/autocross_secrets6.html</a><!-- m -->
Second, the use of the term lower the gravity. For him to say, we lower it for "stronger"(WTF) gravity makes me almost want to puke. Obviously no real research on suspension design, geometry, and engineering has taken place for that comment to be made. I can explain it, but might as well give you this reference that again is simple. (mainy read up on roll center's please, now his is a generalization, but it applies to cars using stock suspension geometry as 99% of drifters are. You can correctly "dump" a car by serious modification of geometry, but I have not seen this in one drifters and actually most road racer's cars. Thats why driftres go into road racing paddocks and go eewww sooo much wheel gap, its cause the road racers actually care.)
Now if you are wayyyy beyond these simple explanations, I would love to have a talk more about suspension as I am just scraping the tip of the iceberg learning about natural frequency rates, motion ratios, and actually being able to understand dyno plots at different frequencies.
I only assumed as I saw nowhere in your pictures of adjusting kingpins or roll center adjustment using lower control arm mounting points and pickups. So I may be completely wrong.
