These come in a set of 4 with specific front and rear inserts. These inserts will be marked which end is which for proper install and the BEST Drive possible.
These Inserts are to fit the VERTEX 6 with VITAVON WHEELS AND STOCK TIRES. These inserts physically lock into the inner lock ring of the wheel and will not side shift. These use the stock foams and give the predictable foam drive but will sidehill like a full insert. Think of them as the ULTIMATE 2-stage system you can tune yourself to get the foams as soft as you could ever want.
NOTE: these will work fine with the Vitavon Portals if you want the extra width
Front inserts are +6mm offset width and rear inserts are 0 offset
