Jerico 4 spd ratio?

The standard Jerico ratio that you see is typically a 3.19 low. If you don't have adequate hook, maybe 3.08 or even less, but only if you are working around less then ideal set up like a street strip car or small tire combo that does not work well. Clutch plays a big role. 4.56? Low rpm engine or street strip? If you can't hook the low gear and adapt the ratios to compensate, get a gear set that is easier to upgrade. Make sure the forst gear set is 33/15 and work with Scott at Jerico to pick the rest. If you plan on ramping up the car to handle the more traditional race ratios, it makes a difference. If you do it right, you can then change only main drive gears to go to a 3.19. If you pick some weird ones, it gets expensive because you have to choose a whole set.
