first, there are three types of infernos. the latest is the inferno kanai III edition, which is quite a high-dollar car. but its worth it! several differences between 1st inferno and the latest one. shocks, chassis, drivetrain, bulkheads, kingpins, etc. have all been revised. so if you want to convert your old inferno to the new standards, you can!... but it would probably cost less just to buy the kanai III edition brand new.
