Build and setup tools cover parts you order before the car comes back together: wheel offset and bolt pattern, injector flow for a horsepower target, and sway-bar rate when you are balancing a chassis. Measure the actual car before you cut or buy — these pages are for planning, not a tape-measure replacement.
Wheel Offset Calculator
Check wheel fitment without fender or suspension rub.
Bolt Pattern Finder
Check wheel bolt pattern compatibility.
Fuel Injector Size Calculator
Fuel injector size needed for target horsepower.
Sway Bar Rate Calculator
Suspension stiffness tuning for handling balance.
