My car has the following options:
- Slipper
3-Racing F/R Shock Towers
3-Racing F/R Suspension mounts
501x shocks
501x CVD's
good screws
Belt rollers/tensioners
Kyosho ball-studs
Even with all this gear, my car has still cost me about US$50 less than my original 501X, and about US$100 less than a 501x worlds.
I beleive that my car as it is now has all the hop-ups it need to be competative at any level - to be honest I cant think of anything else that
needs upgrading.
As I've mentioned elswhere, the fact the the most expensive 501x parts (chassis/bulkheads) are not available as uprgades for the Durga means it should never cost the same as a 501, depending upon where you buy your bits from of course
