sir daxbrandy, tama si sir vulcan, dapat makinis yung ilalim ng axle mo para di sasabit sa mga bato, if you want to make a DIY aluminum to protect your pumpkin, may ginawa si sir paul, I think may mga posted pics sya dito sa thread na to for your reference..

regarding tires, mas favorable ang soft compound for crawling ability kasi mas nakaka grab sya and in 1:1 crawling nagbabbawas sila ng hangin for the same purpose at para di tumatalbog, pro line flat iron, pro line super swamper and pitbulls have super soft compunds, ganun din in some rc4wd tires.. that's just my opinion sir..
