So that would be an issue with your servo, not the cat
.
I do understand what you mean now though!
looking at it though, with the exception of the big bore shocks, the SX2 appears to be a lesser spec'd version than the original SX, especially if you have the stegger brace on it and the modified layshaft.
Maybe the plastic hangers and diff adjusters are there to keep the cost down so the big bores can be included and the kit remain at a reasonable price.
