The FA 3030 is fitted with jets which can be altered and preduce linear, digressive, combination, or progressive dyno curves. The 8060 piston is not fitted with jets and can't be altered
When you purchase a FA 3030 Piston set we provide a valving wizard which can be used as a general guideline.
JRZ Suspension Engineering is pleased to introduce the FA3030 piston. Designed to allow a large range of dyno curves giving the race engineer the possibility to create specific damping characteristics and fine tuning options.
The FA 3030 allows a high response system to be combined with the proven JRZ approach to dampen the unsprung mass. This results in much improved chassis and ride height control while maintaining tire wear and compliance over bumps/kerbs.
