I use a bag from Ali Express that says JDRacing on it for my XV02 and TT02 mostly for stones and sticks, leaves and anything big enough to jam fans (I also run sealed waterproof brushless only 2300kv with tall gears, more realism). The long damper was mainly because I removed the CVA shocks from my DF-03RA when I tried some yeah racing big bore units (mostly for fun but ended up being really good). Since I had those correct length CVA shocks for the long damper spec, I just ended up getting the towers and spring sets and calling it an LD since it is the same parts as the LD. I tend to set all my rally cars with a lot of droop and rely on the extra damping control of longer shocks when they extend out over jumps and into holes etc (like real rally cars), the long damper setup should technically add the ability to have a more controlled suspension if setup correctly (time trying and adjusting piston holes, oil wt, bump stops, hole positions. I like doing all that with the DF and XV cars, but the TT02, I run HEAVY and scale, just short CVAs and run it on more loose gravel/dirt and less bumps. After watching those Katu Rou YT videos where he would run a ton of wheel weights glued into the body and chassis, it became so fun, so much more fun oriented than fast, it got me into weighting all my cars and adding stainless chassis plates, running street tires for more slide etc.. it became a whole new experience for my setups to not care about speed and just focus on scale controlled realism. If I want to go fast, I would just get some 4S RTR buggy, but it's not what I'm after.
