Hi to all and hope your all keeping safe and well in this tym of need. My question I own an mi16 x4 but I'm taking it back to 8v with a turbo n plan on changing the gearbox ratios. Can I install a lower final drive and leave the rest of the system alone or if I change the final drive in the gearbox do I have to change the ratios in the rear diff any help much appreciated thankyou in advance
