I just brought this car back to life it had been sitting for awhile but i never had this problem befor so im pretty confused here.

Also, adding weight up front gains steering, so the aluminum will gain steering over the plastic.

Also, there are many people that run a single lead weight on top of the front bulkhead or on the chassis next to the servo to gain steering (primarily on high bite tracks. Switching to the aluminum is like adding slightly less than a 1/4 oz weight in the front). Adding weight to the front also means you lose rear traction as a smaller percentage of the cars weight will transfer to the rear.

Just put a couple oz`s on the ft end of your ride next time and discover how much steering you lose ....
Its a common mistake thinking more weight on the ft means more steering....
Not trying to call you out , just wish everyone to understand how weight on the ft end works ...
The only time recommend to use extra weight on the ft is when slicks are being use , the extra weight helps keep the ft down from wheelies and the steering is smoothed out ....

To say you gain or lose steering from adding or removing weight, or even lighter and thicker oil can be often mistaken...
Many people say "softer oil up front gives more steering".
This is true, but only in part.... Thicker oil can also give more steering too. It all just depends on where in the corner you are referring to.
Thinner oil can give you more entry steering, due to it allowing the nose to compress quicker, however it will also allow the front end to lift up quicker upon acceleration, which takes away steering.
The opposite is true for thicker oil... Less entry steering, more exiting.
Now with the weights, you have to think in terms of weight transfer.
You can't transfer weight to the nose if the weight is already there.
If you add weight to the nose of the car, the car has a harder time transfering more weight to the nose in the corner. Due to this the car does not have as much entry steering.
However, due to the added weight on the nose, the car has a harder time transfering the weight to the rear of the car under acceleration. This gives more exiting steering, because it keeps the weight on the front end.
So it's really all in perspective, and where in the corner you are refering to. A lot of people refer to on-power and off-power steering as just "steering" which makes it confusing for some.

It is not all about transferring, it is about how much weight is placed on the tires, whether transferred or not. A car maintaining a constant speed has no front/back weight transfer, thus a car with more weight on the front tires has more front traction and thus will push less compared to a car that has more weight on the rear.

But keep in mind, as soon as you accelerate, or under braking, or enter a corner, or exit a corner, this is where weight transfer takes place, and the placement of the weights take effect.
This is why adding weight to the nose will decrease entry steering and increase exiting steering.

mattnin, that is awesome! I hope you plan on testing as many available 13.5 motors as you can.

Try 2oz , it will exgagerate the whole effect & your ride should push entering the turns. And not just a little push , but a lot !
This is how I learned ....
