I'm on MCS 2WR with 700F/1200R on stock bars currently, car works really well. I also have a clutch-type rear diff, and I needed to add a bit of rear spring to get the car loosened back up after adding it.
No bump stops on the shocks (they're MCS too...2WNR 700/1000), but I thiiiiiink the rear adjustable spring perch has a bumpstop.

Car puts down the power very well. Solid subframe bushing and solid rear arms help as they eliminate toe change and deflection under load, such as throttle application.

Could also just soften the rear compression, that will help as well.
.08 degrees. Im not sure if that translates into 1/16" or less.

.08 per side or total? I typically do .12 per side (0.25 deg or 1/8” measured total) and that seems to be a decent balance of power down vs tire wear.

I did the Drexler LSD from driftflo here. It’s a nice unit. For autocross I might loosen it up a little bit from the spec he sent. My stock diff was definitely worn out, and unfortunately they seem to wear quickly.

per side. .16 total.

What behavior would a worn out diff exhibit? My experience/wild-ass-guess is that an open diff tightens up the rear but spins the inside tire. My diff is definitely putting power to the outside rear.

If it's that loose in the rear I would definitely play with shock settings starting with compression before you change spring rates. I would change one thing at a time unless you know exactly what the desired effect of that change is. Otherwise you will be chasing your tail.

Some data. My 2.7/2.1 split seems off, but there are other issues to iron out first.



Current MCS 2WNR shock settings-
F- reb: 15/18
F- comp: 8/14
R- reb: 11/18
R- comp: 5/14

MCS suggested starting settings:
F- Reb: 13/18
F- Comp: 7/14
R- Reb: 11/18
R- comp: 5/14

Of the three lines on the below dyno plots, I believe they are for lowest setting, mid setting, and max setting. There arent lines for every click, so one has to interpolate.

Is this two different settings? what is the 15/18 and 8/14? street/track settings?

What do you mean? He posted the front and rear rebound and compression settings compared to what MCS recommends.

/18 and /14 are just to indicate the range of clicks available.

Thanks didn't occur to me that it was just showing the max values. 😅
