Daryl, just merged your thread with the this one, keep things cleaner.

Here's some things we do:

Main transmission Diff Bearings Font & Rear:
Remove all seals of the diff bearings, just leave the one thats closest to the hole for the drive shaft. This stops the seals from falling out and getting chewed up in the gears. Also lets the oil pass through the bearings which helps them last longer. Make sure you maintain these regularly, clean them with spray cleaner and regrease them with HUDY Grease #106222

Motor Angle:
Make sure you pay close attention to the angle of the motor, front points to the centre line of the car, if you run the motor straight like most cars you will replace clutch bearings every meeting.

Add Weight:
I have added weight to the right side of the car. 20Grams inside the radio box next to the receiver on the furthest to the outside of the car. Also 20Grams in the Front right next to the Steering Servo, this helps ballance the car, helps keep the car flat over jumps and steer evenly left to right.

Above would be the out of the ordinary things that you may not realize, here are a couple of must have options for the car.

++ 12 Degree Catser Blocks - Car comes with 10Degree and they dont really work on our tracks. #352213 Left #352223 Right

++ 10 Hole Pistons - These new pistion really help settle the car down and make it easier to drive in rough conditions. #358034

++ Front Active Diff - If you are looking for more steering or you run on a tight track the Active diff is a great option #355102

++ One Piece Engine Mount - Makes life soooo much easier when replacing clutches etc.

That should just about cover it, let us know if you have any other questions.

Regards
Ari
