FOAM
Had my TC3 working really well last weekend. Followed what a couple of guys at my track were doing using the Dumas front hubs. Weren't any left in the store so I made some. Car works great, with Plaid front and Double Pink in the back, original front tower and middle hole on both towers. This was supposed to take a while to get used to but for me it was fairly easy to drive and quite fast.
I had fun so I was happy. Also put an SSG top deck on there so hopefully that will stop the car tweaking with the battery slots milled out.
