drive face boss / vario bushing -NARAKU- speed-up kit 16mm – 21x37mm for CPI scorte limitate

Description

Variable tuning set for original variators and almost all tuning variators. The speed-up discs can influence the length of the variator sleeve: An extension usually improves the acceleration and a shortening increases the top speed. So before mounting, be sure to measure the length of the original sleeve and then change the dimension of the speed-up sleeve accordingly with the help of the washers!
The kit includes the open racing variator sleeve spacers, washers with 0.1, 0.2 and 0.5mm thickness. Dimensions of the sleeve 16x21x37.
When using in tuning variators, please measure the outer diameter of the installed sleeve beforehand. This should be 21mm.AI-translation
