Has anybody done adjustments to the suspension in the Sport model, or the regular model for that matter? This is something I've been very interested in doing. I was going to have a race shop tune it, but have just started doing it myself by experimenting... Coilover shocks: Set them all to the most firm. This is how I had Tesla set them from the factory, so I haven't compared this to any other setting. Car does feel nice and firm, and reminds me of the feel of my former 3rd gen Mazda RX-7. I'm happy with the firm setting. I'm just assuming this makes a worthwhile difference in handling. Sway Bar: Loosened the front. Adjustable sway bar has three settings. Car comes from the factory using the middle setting front and rear. I changed the front sway bar to the loose setting and left the rear in the middle. Goal was to reduce the extreme understeer that the car has. I'm quite happy with the result. Car is more balanced, understeer lessened but still present (for safety). The extreme understeer seems to be gone. I need to gain more experience driving with the sway bar change. The rear weight bias will mean the rear will be twitchy near the limit. I'm guessing that's why Tesla ships with some rather extreme understeer. Frankly, I found the understeer as it comes from the factory so extreme that I actually consider it unsafe, at least for the way I drive the car. I have enough track experience to be able to balance the oversteer if it starts to come on. At least I think so. I've been told by a Tesla rep that the extreme torque of the electric drive, if driven with TC turned off, can induce sudden rear wheel spin and near instant oversteer (spin out). With the sway bar change, this danger will be increased. I'll play with this in a safe place to see what I experience. Anyone else?
