That only shifted about 18g to the other side and I needed roughly ~48g to be shifted to the battery front side of the tub. I’ve been racing this mod for over a year and love the results. The car balances out perfectly and it responds almost as good as my VTA chassis. I did have to use ABS adhere a custom 3 D printed floor on the battery side. I use Velcro to hold my battery down so it works well.

on a side note… if you want to remove all the slip out of your suspension use ABS epoxy and fill the suspension arm mounting holes with it. Then coat the suspension arms with Vaseline and insert them into the correct mounting holes filled with epoxy. Let that cure overnight. The Vaseline allows the arms to be removed easily making a perfect fit for the joint. That’s how I setup all my TTs.
