I run 94t spur and 43t pinion in 17.5 blinky.
I was racing last night with Tamiya slicks. Same inserts all around (Medium).
I really like the aerated shocks built so they have 0 rebound. The car is fantastic on carpet with these (and the montech nazda 4 shell)
Here is a pic of the shell

The thing is built to be 'Dead' these shocks dont leak and they are very consistent for me every week.
