Dear All,

- After how many lt you change the rear bearing from .12, .21 On Road and .21 Off Road Sirio Engines?
.12 Sirio Evo 3(& STI)
.21 PR Pro & WCR(&STI if you know0
.21 Kanai(&STI)
- And the Conrod?

P.S.
I change mine PR Pro rear bearing every 4 lt of 25% Kyosho Fuel.
The conrod every 8lt

Thanks in advance.
Nick
