This does alter the droop levels, however that is not the reasoning for doing it. When the shock tower is raised, it alters the level of progression as the shock travels up to full compression.

The lower the tower is, the more angle the shock will gain as it is compressed, causing the shock to feel stiffer as it compresses.

When you raise the shock tower up this .060" it keeps the shock straighter as it raises up, keeping the shock more linear as it compresses.

With the stock design, the shock will become stiffer as you roll onto it more in the corner. However, when you raise it up, the shock feels softer than the stock geometry. Doing this makes the car feel more forgiving, since you will gain more traction when you need it.

Keep in mind, this is more of a mod to do when the traction is low, or your front end is overpowering the rear end. If you have a lot of rear end grip already, this will cause the rear end to dump over to much...

If your track is medium to low bite, this will improve the stability of the car. It's worth trying if you have the time.

What pinions are people running with the stock spur gear for the B4/T4 when running a 17.5 and 13.5 in their B4/T4?

13.5 in my B4. Running a 26/81 currently. It is still not geared to its full potential. But that's the largest pinion I currently have. I've seen people running 28+/78.

No pat answer. Too much depends on the batteries you're using and the layout of the track you're running.

True that, Iwould imagine a 17.5 would be geared way higher!

I have my B4 geared at 65/34 with a 17.5 and it seems to be good at alot of tracks. I have the Turbo hub on there so I can run the kimbro spur. Way punchy and very quick down the straight with no drop off.

So honestly... I need to find a the smallest range of pinions I will need running the B4/T4 on an indoor 100x50 high bite technical track.. I will get Associated's smaller spurs they got which is the 78toother for the B4 and T4. And I will run Losi Pinions. So I wonder what ones I will need

I remeber I would gear my old B4 with a 19 tooth and the truck with a 17 toother.. SO I dunno!

For the 17.5, you're going to have to get the slipper eliminator and run a much smaller spur if you want its max potential. A 78 spur and 30 pinion will not even come close
