I'm looking at getting a tamiya highlift and turn it into a crawler, but i don't know how to make it sit higher up and get more ground clearance and be able to stuff bigger tires under it so the diffs don't scrape. also ive seen how to lock up diffs for these things with epoxy but i don't know if i should lock both diffs or just the rear. also besides the tamiya highlift what is another good conversion truck for a crawler
