Hey Zuki crew, I’m new to the forum, hopefully someone can help. My Zuki is a show car or competition car. I drive it a hand full of times a year. My question is what, gears can I put in my stock rear to get my Zuki pass 65 without it screaming rpms. Or atleast go 70 without it screaming 5500 rpms. I’m reasonable 3000rpms will be fine. I have a 1983 Toyota Corolla 1.8 motor and transmission automatic. So I was hoping I can put gears from another Zuki that would fit right in my stock rear. Plug and play set up. And I dnt want to change my 20 wheels neither. So is it possible?
