I'm planning to start by running 2WD stock class (17.5) at SDRC. It was suggested that i install the slipper eliminator (Kimbrough 69T spur and slipper eliminator) for running stock.

My first question is, for those that run stock, do you still have the slipper installed? Or do you use the eliminator?

My second question is, for those who use the slipper (stock or otherwise), how do you assemble it so that the pad stays aligned with the plates as you are tightening everything down? I keep having the pads slip away from the center spur and then rotate slightly so that the edge holes on the pad no longer align with the little tabs on the gear. As a result i don't think i'm getting good contact between the plates and the pads, and i'm having a really tough time getting it adjusted correctly. Any advice on building and setting the slipper would be welcome. Thanks!

Josh
I'm running stock (about 90 miles north of ya) and am using the Avid Triad slipper. Like the other guy said, use something small to help assist keeping things in place, I always struggle with slippers. I might go the eliminator route in a few months just to see if I notice a difference. I only have 2 track days on it so far, and am running it rear motor. So far so good though, I love it!

Try this. Grab the gear and place the pad on it so it is facing the sky. Take the slipper plate and put it on top of the pad. Now take the car and turn it over so the top shaft will slide through the slipper plate, pad, and gear assembly you just built. Push it all of the way on. Now hold it on and slowly rotate the car over 180 degrees so the gear is now facing the sky. Install the remaining pad, slipper plate, spring retainer (if equipped), spring, spring retainer and nut. Tighten the nut until there is enough pressure on the slipper plate to keep it in position. Then place the car on the wheels and proceed to adjusting the slipper when ready. You could probably use the same steps with the slipper eliminator if needed. I hope that made sense.

That makes a lot of sense, thanks! The eliminator is easy to install, it's just the pads that keep coming out of alignment. I'll try the idea above and see if it helps.

Has anyone tried the Schelle 4-hole 1.4 + 1.1, 1.5 + 1.1, or 1.6 + 1.1 pistons? If so, please share you experiences including shock oil used etc. Going to try 1.4 in front and 1.6 in rear with 32/30 oil respectively.

The benefits of a gear diff is durability and consistency.

A ball diff is much easier to adjust and is more efficient when adjusted properly.

I have been running a gear diff on medium traction clay for about 2 months now. I put it into action when my ball diff gave out during a race. I like the gear diff because it gives me one less thing to worry about.

Yes, that would be the one.

It comes in red and green which are identical, double cover (two levels) then it comes in blue in a single level and a double double, which is essentially two of the double level ones conected back to back

I don't understand why the gear diff gets a bad wrap. I told a guy I was running one last week and he looked at me like I was a moron or something. I'm fairly certain that it's my driving skills holding me back and not the gear diff though 😉

A ball diff can generally give better traction on lower bite surfaces. Unlike a gear diff it doesn't really pack up much when more power is run through the diff. It comes down to personal preference to which you run.

Is it better to run the diff tighter or looser?

I run it until I can hold one tire and spin the other one spins 1/2 a turn when spun. I mean but heck maybe my diff setting is why my car is loose.

I run on a medium bite track where traction is lacking and I have my car pretty good right now.
Problems specifically ... Well , the car will spin on the straight at half throttle using a novak pulse , and 8.5 turned down to about 75%. Im using the same tires the winner used , Super soft calibers. My corner speed is next to nothing. I bought the car set up MM and loved it on the old surface . Its set up servo, esc, shorty, motor.

I tested with the zack rogers setup yesterday. Have the exact setup, I could not get the rear to stop swinging around. What are the electronics on the car? Mine are shorty to motor and esc behind servo. I tried white fronts as well. This with 8.5 motor and dirt webs sauced golds for indoor clay. The b5ms can put down the power super easy.

Also thinking of going RM on my second car to test back to back.
