The standard inserts are
27.5°, 30°, 32.5°, 35°, 37.5°
The timing you will get with the reversed is;
R37.5°(37.5°), R35°(40°), R32.5°(42.5°), R30°(45°), R27.5°(47.5°)
37.5° is horizontal. So reversing it does nothing. When you line them all up it become obvious.
I think LRP need to start marking them this way! With the abundance of Blinky racing now, the stock inserts are no where near aggressive if used the right way round.
My 13.5t is running 37.5° and 3.9FDR and it is coming off at about 60-65deg (3/4 blinks on the speedo, which means 35/30deg away from shutdown (100deg I understand). I'm going to see how much I can push the timing up before hitting 80-90deg, and can then put the FDR back to something like 4.1ish I expect.
