That makes sense
Those springs have more initial rate than Silver or Pink

What body are you using
I think low diffs almost always the better setup

Was your car sliding front & rear the same ?

Maybe for stock or for the old CRC carpet, but I personally don't agree for the new CRC carpet or for mod. My impression when going diffs high at Denver was that it made the car feel a bit more free and also made the car feel more consistent over the entire run. I haven't run stock or on the old carpet, though, so who knows

I know that Andrew H was running diffs high with silver/black springs and a front gear diff with ride hard putty at ROAR nats. Word from the ETS guys was also diffs high on carpet - 'always'. But that would, again, be for mod.

So maybe the moral of the story is to trust no one

Dude says he's looking for side grip
Low diffs fo sho
I always run a 2.5m front diff, but that's just a preference
Our carpet is less carpet, more carpet backing these days, maybe similar to ETS rug

Sorry - 'I think low diffs almost always the better setup' - didn't think you were referring to just this case. Carry on.

I don't know how someone didn't have enough traction on the new carpet. I was driving it on edge. That new stuff has instagrip. The stock out of the box setup was pretty dang good with that RSD pink rear springs, Gold fronts and the aluminum chassis. This was also with a LTCR body.

Don't have a setup for new CRC Black carpet
Our old CRC rug is several years old and missing most of it's fibers in the sweepers

Still fun though

Used volante tires and schumacher sxt3.0 additive.
Car was terrible with x braces, then I removed and was better and put the shocks from 3rd hole to 2nd and better, but still was very hard to drive. It just couldnt create any side grip. Also tried different sauces and xray front2.5-2.8 rear 2.7 springs but nothing.
wondering what would happen if I had put the diffs in low position.
few things to try:

- ff4.9 fr4.2(separate) rf2.7 rr6.4: wide car on carpet seems more stable, but still with good corner speed, also on smaller tracks
- diffs down
- graphite C-hubs
- 1.3 post sway bar
- 4 Yokomo blue springs
- Hudy additive
- 5.4 / 4.4 downstop (try also 5.0 / 4.0)
- long post camber link (you need shorter threaded balls)
- 4 mm inner ant link shims

I made several tests on carpet and asphalt, in my opinion the car needs to roll much more than the old 2015, has anyone tried in this direction?

The carpet was 2 years old so it doesnt have grip like new. Thanks for the tips. I will buy the suspension mounts. I will race on tarmac from now on so will these settings still may helpful on medium grip asphalt?

Diffs up should give more roll

on tarmac it depends on the tires you use, but generally I found that wide car doesn't give advantages, I use almost always ff3.5 fr3.5 rf2.0 rr5.7, very close to the basic setting

diff always down

other settings can be useful, you can try, except the additive obviously

yes, but for me the diffs down generate more overall traction in all cases
