Nice. TFS.

Tried out the new aluminum gear diffs. What a world of difference. I used one with 5K and another with 3K of diff fluid. They were consistent in the way they felt all day. The fact that I was able to use the red o rings meant that there was less friction overall. I highly recommend getting these if you can swing the steep price.

having a hard time letting go but will have to let go of all 3 of my 419 cars 2 xws and one x car if anyone is interested there is a lot of spare parts included even more then shown. but due to time I will only be running 12th now for a while

That is sad Snopro, good luck in your next car.

Hi guys.

just wondering what diff and spool setting people use on carpet?

before I converted my x into an xr I always ran the diffs in the high position as per manual but since going to XR I've had them in the low position.

I'm going to try them high on Friday night, hoping it will liven the car up a little?

Do you run the centre deck or the turnbuckle? If running the deck, try the turnbuckle, and then try it without. You will be surprised on how different the car responds with those three settings.

Currently running the centre stiffener on the softest setting (bolted straight through from the bottom) I have tried the turnbuckle but found it a bit in consistent.

might give it another try.

what's your thoughts on the diff positions?

Raising the differential will result in more onpower traction in the end you raised it. It has to do with the driveshaft angles, which will straighten out, when accelerating, and pushing arms down. Its not a COG matter, as many think...

Wow. The more you know.

Yes. But i have to say, it's not generally a thing of raising or lowering the diff. Every car has other conditions. It's only a matter of the driveshaft angles relatively to your outdrives. The more angeled they are, the more traction will be produced on power, because they tend to straight out horizontal, when rotating. It's a bit of try and error. Both diffs in low or high position will result in a rather neutral behaviour.

An example for better understanding (sorry for the EVO7 pic, I had it right now on the phone):

Thanks Tom that's a great explanation.

So with the 419xr I actually have a greater driveshaft angle with the diff in the low position, so raising the diff is likely to reduce on power grip.

I'll give it a try tonight along with the turnbuckle centre.

Yes, try it. For your XR: if you need more on power steering = front low, rear high. If you need more rear on power grip on corner exit = rear low, front high.

The car was amazing tonight, I ran spool and diff in the high position along with the turnbuckle centre brace and it was like a new car.

My mate who is usually running similar times to me every week was nowhere to be seen even with my 8 meet old tyres.
