Hey Chris

I put the one way layshaft on my Cat SX and I am loving it. Though saying that, I wanted to drive way more aggressively. And would not advise it for starting out.

If you are starting racing than I would suggest you just get used to the car with the standard set-up, and enjoy racing consistently. You should pick up a one way if you are curious, and check out the difference. Practice and track time is a priority. Making the car more challenging to drive with the one way layshaft or dif will really put you off.

You will be surprised, with the stock set up and consistent driving you will be over taking people easily. You really don't need all of the extra stuff for a while.

I found myself less than one second per lap behind the fastest guy during my first off road race with the standard kit. Easy.

Different shock oils, the racing spring kit and the sway bar kits are things you should consider once you are lapping with consistent times. I am also running medium flex arms on bumpy tracks.

Buy some extra bumper screws if you think you might have a learning curve with jumps. I have only gone through one set first.

Hope that helps.
Have fun, race the clock and avoid crashing.
