I go with the lowest ride hight possible, as it lower the centre of gravity and stops the weight from bieng thrown around too much.
I also have the firmest suspension possible
 
I'm not pro drift but my experience here is if you leave it ride height neutral and adjust the springs so the car is drivable you will be able to steer into the corner and point the car into the apex and get much better control overall of how and where you want your drift car to go. If you need help breaking the wheels loose, use the dampers to stiffen the rear end until it spins when you hit the throttle deliberately for that purpose, if you find it spins too easy than take your dampers down a notch. Stiffening the rear anti-roll bars can help here as well. You'll also find it easier to control if the LSD acceleration is maxed out (60), and having initial and brake set to at least 20 and upwards of 30 will probably help.

Lowering the ride height does lower the center of gravity but if you lower it too much the car will try to "roll over itself" so that's defeating the purpose of you even lowering it. I always go anywhere between -10 and -15 mm of lowered ride height (varying per vehicle) because it will still have some travel and won't bottom out the second you steer into a corner but the car will transfer weight a bit more evenly.

Spring rate is the amount of force the actual coil spring carries. For example, a coil that is stiffer will "carry" more weight than a coil that is softer.

This may seem confusing but try to read into this Just because it "carries" more weight doesn't mean it's better for the application. Usually you will want (depending on the vehicle) a set up that is stiffer than stock when building a vehicle for drifting/racing applications. I know this isn't always true because my mustang gt set up for drifting came with a 9.2 or 9.0 kgf/mm in the front and I thought that was entirely too stiff! The car just wanted to understeer. But mostly due to the fact that the rear wasn't too far off from that. If you want more forward bite then keep the numbers (Front and rear) a bit closer but for drifting you want it to have forward and cornering capabilities so one end sometimes can be stiffer than the other and you will gain more grip on the softer end.

My Mustang set up now is 9.3kgf/mm in the front and 5.8kgf/mm in the rear..and granted that seems like a big difference, it gives the car more grip in the rear (where you need it most) to help control the slide more..other guys will probably enjoy these numbers being swapped around but then you suffer more understeer going into the turn. It all just varies on the driver at this point. NEVER just throw some crazy super soft/super hard springs on because gradual (increments of like 0.5) can be much more rewarding to actually understand HOW the car is reacting so you can learn to dial in your own set ups.

Dampers gauge the rate that the actual cartridge travels. The cartridge is what reduces the coil's ability to just bounce up and down indefinitely. It "dampens" this effect and controls this motion more evenly so the driver doesn't complain about going over a bump and it bounces up and down and up and down.:scared:

Think of damper compression as how the suspension reacts when it collapses. You go over a speed bump and what does the car want to do? Shove all the weight it can up front which lowers the active ride height for a split second. When it gets to the end of it's travel, that is the compression motion. If you set the compression number higher (from 4 to 5 to 6 to 7, etc.) it will go through this process must faster.

Damper extension is like the rebound of that. What goes up must come down. But in this instance, what goes down must come back up. If you set the extension number higher, it will go through this process must faster. It will "pull" the weight off this area and evenly distribute it back to it's original position after you have exited the speed bump. The lower the number, the longer it will take for the weight to "pull" itself off. So I usually have my rear at least 1 lower than the front so the weight can "stay" over the rear axles as I'm corning, which increases driver control due to more grip.

Roll bars are tricky. Roll bars are (called various things) Anti-Sway bars, Stabilizer bars, all it is essentially is keeping vehicle more controllable around corners. The bar connects from left to right and as you go into a corner, if you turn left, where does most of the weight try to go? On the driverside front tire. So now that tire is super stressed out and wants some relief..well it can't do it on its own so this is where the roll bar comes into play. As that right tire is collapsing in suspension travel, your left front wheel loses a lot of that weight and has less grip. The roll bar tries to "even this out". It twists as the weight becomes uneven to produce a great force on the left front wheel to shove it back down onto the road so you can have more grip.

It can only do so much but can't fully overcome the cornering effect. If the number is too low (closer to 0)..just try it and see what happens :sly:..and if the number is too high..then..I'm not sure how to explain this one. But following this is a quote from wiki

Wiki
Anti-roll bars provide two main functions. The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width.
The other function of anti-roll bars is to tune the handling balance of a car. Understeer or oversteer behavior can be tuned out by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing the proportion of roll stiffness at the front will increase the proportion of the total load transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a comparatively higher slip angle, and the outer rear wheel to run at a comparatively lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer.

I have posted this at the newbie drift project thread, ^ props to Stunt Drift, but maybe someone can put ours together and be able to understand easier.


Rule of thumb... set up for under steer. Because u need to control the drift.

I set my suspension between 9 and 12 on all my cars depending on their weight and size. Having a tighter (higher #) front end increases understeer, and visa-ve. If u lower your car alot, tightening the suspension is a must ie. u lower ur car like -10... tightn that ****. lol

By having your front Shocks compression lower than the rear, this allows it to compress more than the back so the weight can transfer faster which allows for quick chicane-ing/feinting down a straight (makes it easier to do side to side motions). Set the front compression 2 to 3 points lower than the rear. Have the extension be 1 to 2 points higher than your compression in your setup.

Some people use roll bars some dont. I never have either front or rear over 4, if set to high, u wont be able to turn, or visa-ve. If the front is tighter (high #) than the rear ie. 4/2 u r set up to understeer, 2/4 is oversteer.

Camber has a sweet spot, more camber you have up to a point gives you more grip. More camber in the front causes more grip during cornering, this can be used to dial in your cars tune to get the right amount of over/understeer. Front camber governs understeer, rear governs oversteer. I dont go over 6 on either.

Toe is something some dont bother with, toe out (-) in the front helps initial turn in but decreases control on the straight at high speed (but we are drifting...) Never set either as high as 4... 4 is high enough, how about we say 3... yeah, 3. Toe out(-) in the rear helps you do lift off drifts (umm, excelerate hard into a corner then let off as u turn, good for long corners) better and power over steer (pow-over drift... just mash the X button and turn then counter steer and hope for the best :scared: roflcakes).

One more rule of my thumb... you dont have to have ur settings be an even number, just staggered evenly. ie. 9.5/11.5 or 12.3/11.3, ya feel me? lol

Once you become familiar with the settings and understand it, you will be able to make up ur own as you go and maybe share it with others! 💡

Well, hope this help somebody, any Q's just ask! :)

Ride height- The lower the car, the lower the center of gravity, and the less weight transfer you get. You also get less body roll since you're not as high up. I generally lower the car to about 5 away from max low since all the way down doesn't leave your suspension room to compress.

Spring rate- This is what stiffens your car. The higher the spring rate, the less the car will roll. In road racing, the stiffer up front, the more the car will understeer. This should be related to your ride height. If you lowered your car only a few mm's, raise your spring rates a few points as well. You generally want a stiffer car to drift with, just not TOO stiff, otherwise it gets snappy.

Dampers- I'm not an expert on this one, maybe someone else will chime in.

Anti-roll bar- This stiffens the front and back of your vehicle. The more you stiffetn the back, the more your car will generally oversteer. The more you stiffen the front, the more you will understeer generally. Find the right balance, and match it with your spring rate settings.
 
waits for TTCHs detailed response...lol

LOL only just saw this. Sorry, but there will be no detailed response tonight, it'll have to wait until tomorrow night as I have work in 5 hours (drift instructing at Santa Pod all day :D ) and need some sleep :)
