I have weighed my battery and esc and per mm mine are the same weight. So the only difference is the weight of the wire. Typically I ran my car servo, receiver, battery, esc, motor.

My diff gear won't spin if I hold the wheels down but say if I hold the spur gear and turn one of the tires, there is a good amount of drag from the diff. I can't run my diff loose with the spur gear locked down. The car won't exit the corner well. I wish that there was a torque setting I could give you for the diff nut haha it would be so much easier to describe

In regards to the side spring: compressing the spring will numb the car some and taking preload away typically quicken up the turning and twitchiness.

What tires are you running? I run shimizu 74/75 on carpet but I am only saucing the inner third of the front tire.

71/72's on the car. Battery rearward and electronics up front helped. Need a twitch more steering so im trying standing the front shocks up to yhe top hole. Still black sidesprings.

Using an F103 style thrust washer vs the F104 bearing diff thrust has been known to help cure 'diffing out' as you have described it. The F103 style has more differential resistance which may help just on carpet.

are you running 21.5 or 25.5?

I always use team associated clear diff lube on asphalt.. for 21.5 carpet you may want to try tamiya or 3racing's anti-wear grease applied to every other ball.

25.5 lately I have just been using team associated diff lube on both carpet and asphalt.

I'm currently running 21.5 on carpet. I think we are going to 25.5 though. thanks for the input.

I would go for a slightly harder centre shock spring.

It will give you overall less steering and better rear traction and stability. Practically an easier car to drive. Remember that the rear wheels do everything in F1 - acceleration and breaking - so if you use the added rear traction well and make up for the lost steering by say applying sauce to the front wheels or a softer front spring or a different front tyre, it would mean more overall traction.

A very important gain is that it will take longer to kill your rear tyres!

But I would definitely try tightening the diff down

My front end has the entire exotek upgrades. About $100 for entire upper and lower parts but money well spent

I'm missing the IRS and upper links, but thought I'd do a 190mm with a different lower arm set.
