Here is the fix I came up with to gain a little more rear grip for Clay/dirt tracks it works in all motor configurations it's very simple to make just cut out a small piece of .5 or 1 mm carbon fiber attach between The sway bar mount and rear transmission housing that gives you a flat surface to use stick on weights start with 1/2 ounce I have found that three quarters of an ounce is the sweet spot on my car just remember when adding or removing weights trackside each quarter ounce weight is worth one turn plus or minus on the shock collars this Balise trick company with clever electronic placement and a super Shorty Lipo (that is plenty of power for stock racing ) adds consistency and drivability to this car on Lower grip tracks
