Guide Lines for Adjusting 2 way external coilovers
Hey all,
I just installed MCS 2 way external reservoir coilovers on my X. And may i say i was not prepared at all during my first track day. These are on a whole over level. I am looking for some general guideline on adjustment and just any advise you guys can share on adjusted these bad boys.

Thanks all

Thanks for the link. Ive been doing some self research and i have read some articles saying to start in the middle and go from there, others say start bump and rebound full soft, adjust rebound till laps times fall off then do same with bump. So i have some good starting points to go off of. I could always give Wyatt a call at MCS when I'm at my next track day for some pointers. Keep them coming guys.
Thanks

Looking at your other thread, you seem to run way too much compression for those. Have in mind that compression adjuster is for high speed with little effect to low speed, so changing it that drastically on the track seem to be way more that I would recommend.
I have to say that I have not run those with stiffer springs, but on stock setup, I run 12/14 F/R for the rebound and 6 for compression all around. You are running much more spring that I do, so it is puzzling to me that your setup is at 11/10 rebound/compression all around. With that said, I would expect you having to run much higher rebound numbers to keep those springs under control and not much of a change with high speed compression from around 5. I wish we would have low speed adjuster instead, but it is what it is. With high speed only, there is not much we can tune with it other than how to conform to very bumpy surface, which most of the tracks are not...
There is also a possibility that you have a custom valving for yours and that would throw all of what I wrote above into the trash bin.

Should be the other way around.

I was even considering of getting 3-way adjusters and taking off high speed knob to use them in B-Street, where only two are allowed.

Actually, I can not agree on this one! Most of the 2-ways I have seen are using high speed compression adjuster for some reason unknown to me. Penske 8300 is another example for the same thing. Few other ones that I have taken into consideration were also all high speed. As of MCS, I have not verify it with them, but even a main we page is showing high speed there as well.

Very interesting. Good to know.
Silly that they would do that. I would much rather have low speed adjustment than high speed if I had to pick one.

Tire PSI is set to 36psi hot with RE71r tires.

No custom valving just off the self stuff. Like i said i should have done more research before my first day out. I was just kinda going on feel and what i thought was good as far as stiffness and control. Now i have more information. 11/10 felt harsh. My JRZs where alway ran on 18-19 out of 20 clicks. I was basing the MCS on these witch i should not have.
Possibility is that last few clicks are more sensitive since it is getting closer to the fully closed orifice on adjuster and I don't want to be there. Having at least 2 clicks left is what I would like to have. The way they are right now, I will be almost full stiff on asphalt and there will be nothing left for concrete adjustment at all. Guys from MCS told me to try it and if needed they would re-valve them.
