I've ran 3 toyotas I own personally with 35s in them and tires from 33-40" with a 300hp v8. I have not broken a precision due to it wearing. Only from being stupid and dumping the clutch at 4500 rpm on asphalt with 38.5x16-15 tsl's on 15x14 steel wheels. That's alot of weight to twist. Never once failed a precision with a 4cyl or v6 truck. Including abusing them with 40s on a 4cyl truck.
