Tarett Prototype Rear Swaybar, Pics of install Options

[eeyore]

I'm the lucky sap who got to work with Ira at Tarett Engineering and have my car be the test mule for rear swaybar development.

We got a chance to test the prototype rear swaybar at the PCA SDR autocross last weekend.

Here's all the gory details. I felt the need to be wordy so as to help provide and accurate picture.

(The content are my own words. Although I have been given permission to discuss this, I want to make it clear that I am not speaking for Ira.)

Initial set-up, rear swaybar at 50% stiff
On slow transitions into sweeping turns, oversteer existed but was not a terrible problem. However, negotiating the slalom was very difficult. The car would make the first turn, but the rapid transition to the next would just swing the back end right out. The abruptness instilled a bit of hesitation in me on the slalom for the remainder of the day. There were occasional incidents of inside rear-wheel spin, but also some incidents of (slight) throttle-on oversteer.

Second set-up, rear swaybar at full soft
Great improvement. The oversteer had gone from abrupt to very mild/just right. The car became very predictable. Happiness was restored. DB went from dissatisfaction with the car to pleased. The car could be tossed from side to side without worry of the back end coming around. There seemed to be more incidents where the car could coaxed into throttle-on oversteer and very little (zero?) incidents of inside rear-wheel spin.
