No your not. lol You will never get past 90% done. As soon as you think it's done, you'll want to change something. I've had mine for a year and work on it at least once a week, but I think I've only driven it a few hundred feet.

The best upgrades in my opinion are in this order.

1. bearings, duratrax ones are fine or the ones on ebay.
2. traxxas evx2 esc, it's waterproof and handles a lot of power.
3. hi torque servo, crawfordperformanceengineering.com has some you can get for $20 and they have 200 ozin of torque. They work really well.
4. Shocks, tmaxx pro shocks or team associated "tmaxx shocks)
5. 4-link kit. So many options on this one
6. Adjustable motor mounts, this way you can change the gearing to tailor the power to your driving style/conditions.
7. Motors- duh.
