it’s the same springs as ld3m so chances are you’ll want to change them out, depending on your conditions. I would suspect the AE machined pistons work, I think Schumacher have some too. Or check out the VRP pistons. Petit RC has some decent setups for most track types.

alloy servo horn always a good shout - the kit one is a bit rubbish unless you superglue it together.

take a look at the v4 ball diff when the v3 kit one is worn out - it’s so much better and longer lasting.
