Just bought a Japanese import here in the Philippines!

Just got a SC here in the Philippines, converted to RH drive though! But they did manage to do a good job at it! Everything seems to a very standard issue, I will be using this for business/ personal use. Business= supply of dry goods to restaurants, any advice on mods and wheels to buy? Should I have better suspension at the rear wheels? Please do tell me, will start modifying in 2-3 days, just want to plan it out! This monster is awesome.

The suspension should be fine, designed to take 6 sumo wrestlers or 8 adults. Never had a problem loading it apart from once when the rear tyres rubbed on the wheel arch but that was a lot of stones slabs all at the back!
