Cat K1 upgrades/spares

[Dodgy Guy]

Can anyone tell me if I will need to upgrade any known weak parts on the K1 and which spares will I need to carry?
Thanks

If you race mostly on astro turf I strongly recommend using geared diffs, low maintenance and drive better through the turns, I haven't looked back since switching to them

Alloy gear box tops

As Bobbin says I think the geared diffs are a step forward, especially in the dry. Most people seem to use 10k oil in the front and 5-7k oil in the rear.
The alloy gearbox upper housing for the front are good, I haven't bothered with the rear as the plastic one seems strong enough. The alloy front suspension hangars are also good. The new rosé joints also look good as you can capture them so shouldn't pop off, the standard grey ballcups can be a bit weak and pop off a bit too easy.

Would the gear diffs fit the SX3?
I notice that the K1 diff pulley is different, but only subtely.

I'm using 10k in the front and 5k in the back which works well for me, I know some of the team drivers are using 10k all round with great success
