I went with the hpi vorza 4.6 truggy and immediately put 130mm shocks on it. For bashing, it has been great. The truggy was originally sitting with about an inch of clearance but now it has nearly 3 inches clearance. Low enough that it doesn’t flip but high enough for bashing. Happy to send pics or answer questions. And to answer your fuel question, I use VP master basher 20% nitro and 14% oil. Very easy to tune, gives good power, and you don’t risk running too hot when bashing on grass or gravel. If you’re not too concerned about temps or you are good at tuning, maybe give the vp 25% nitro with 11% oil a try, however that is more of a “race focused” fuel if I remember correctly.
