Can you please share costs?
Yes, the yokos have road noise. Since I changed after two full fuel tanks, I cant really compare fuel consumption. It has been consistent 11-11.6km/ltr for me with both tires (4-5 odd fuel tanks with yokos, total 4000 km driven). My route is mild traffic, and 25-30% actual highway.
I did a road trip in Dec'21 with luggage, weighing about 130-140kg in the dala, and another 40kg on the back seats. The ride became almost SUV like, in terms of the bouncy behaviour and shock hardness, even with local leaf springs. It was a friend's Revo G FL. He had slapped on nitto duragrapplers, and they are probabaly the quietest tires I have experienced. Had to search for road noise. And soft too, being HT.
I suspect your experience with thai shocks and 60-70kg weight should be similar. As I mentioned earlier, with just 35kg weight in Daala, my current Revo stopped bouncing about violently on breakers and bumps.
Unfortunately, I dont have any link for thai shocks. Toyota central and unichip did mention comfort suspension for Revo sometime back.
What agriauto shocks did you recently install? Front or back? If you want the rear to stop being a back breaker, you need 120kg odd in the daala with local leaf springs.
