Chassis Set Up and Race Record Sheets

Winning races depends on a good chassis set up and accurate record keeping.  Recording your chassis set up and race records take the guess work out of racing. Knowing what set up to use or not to use allows you to make the right decisions for specific tracks or track conditions. Diagonal percentage, tire stagger, air pressure, gear ratio, shocks, springs, and fuel levels all contribute to a winning set up.  Document all this valuable information on these set up sheets and keep them in your Race tech Workbook for future reference race after race and year after year.

 

Shock Maintenance & Custom Valved Rebuilds

The off season is the perfect time to re-evaluate your shock program. You use this time to rebuild & repair your engines, you should take this time to rebuild and repair your shocks as well. A shock is a cylinder made up of seals, valves, bleeds and oil. Over the course of a season dirt and grime can penetrate the cylinder and get inside. When this happens the shock will begin to wear out and fade. For more shock information  click here
