You probably want to add to your list a 3Racing aluminum gear box. It comes with some bearings inside that allow your micro t differential and transmission to move much easier thus increasing speed and efficienc; for around $20 is a big improvement. Since you are going brushless you need a lipo battery, and the original team losi lipo battery works great, with charger is something like $50. The Team Orion 10300KV motor is a beast but it will cost you another $25. Some bigger tires would make the car go faster, you loose torque but you will gain final speed reason why you can try using the Losi Micro 22' on-road tires, the set of mounted tires retails for around $10. I have no clue how fast is my micro t with all these upgrades but is sure fast in eating up my cash. I have invest more than $300 and that is with no spectrum radio nor expensive high end chassis or fancy shocks. Any way good luck with your project. Email me at notwithmyname@yahoo.com

Here I am attempting to put together the best Micro-T setup for performance.
The fastest known speed for a Micro-T is 51mph, I want to get together Micro-T fanatics to beat that with a new record!

3Racing Graphite Chassis (Light,close to stock setup)
Futaba S3154 Servo (Fastest,Digital)
Team Orion 1/36 Brushless Motor (???need comparison to Losi???)
Spektrum S3500 Receiver (Lightest 2.4GHz Rx)
Hot Racing Oil-Filled Suspension (High-quality make)
GPM Alloy Rear Camber Links (Only make of alloy rear cambers)
Team Losi Shock Fluid 60wt (Thick, but far thinner than grease; high quality)
Viverrine 6A Brushless ESC (Smallest, more configurable...need performance review)

I'd like more comparisons of various products...basically I have listed parts I have found to have unique qualities that set them apart from other manufacturers.

Feel free to help out! :)
