how about this one

Pic taken at WGI during opening weekend, technically paced at 55 mph however we hit north of 100 on a couple section of track. It depends on the group you go with and the pace driver

One of those turbo Focus. He was pretty fast. I don’t know if he was stock but he was a PIA. We weren’t allowed to pass. On longer runs he would hold back then do a high speed charge, again not allowed and as I’d come up on a RH turn, he’d be on my RH side as though he was going to pass me on the right. We’d be doing around 80 mph

How does where a shock mounts effect instant center?
From talking to both Mike and Shaun, I believe the geometry of both setups is very similar.
I suspect the results might be similar too.

From what I recall, the mounting spot for the shocks on the MMI setup was so someone could go with their coil over set up without requiring a change to the lower control arm.

I’ll be going with MMI within the next year for my car due to this reason, as well as other reasons.

What other reasons are you referring to?

Cant speak for MMI, but the SOT front suspension completely transformed my car. One of the best mods Ive done.

It doesn't, except for strut suspensions. It does affect the Motion Ratio, or how much the spring/shock travels compared the the actual wheel travel.

While I haven't worked out the math myself, Mike claims a motion ratio of 1.7 which is similar to Shaun's I believe. The lower shock mounting point on the MMI is sort of under the ball joint if you look closely.
Mike touts the superior JRi shock. I am not sure it is superior to Shauns Bilstein. At the end of the day, it's all about valving.
Comparing Mikes Mod 1 to Shaun's (having never driven neither - I have Global West) I think they are similar.
MMI- Mike is a world class driver and you get that experience. He's also not afraid to think out of the box.
SoT - better value and great support customer service.
If I were comparing the MMI Mod 1 to SOT to purchase, I would likely buy the SOT due to price.
If I had unlimited money and fab skills, I would buy the MMI Mod 2 setup.

We have plenty of VMF members with Shaun’s coilover setup but I don’t know of any with Mike’s. It’s hard to get a good feel for the differences between the two when there is no one (at least no one chiming in) that has experience with both setups

There is a long time member here with a red mustang that has the MMI front suspension.
Heís also a MCA judge I believe?

Do you know who? I’d be interested to hear from this member if still active on this site

I think Trkpny2 is the member with the MMI front suspension.

BTW Chuck (Trkpny2) in an old post claims 6 - 8 seconds gain at Sears Point with the MMI suspension compared to what he had before. I don't know what his previous setup was however. Maybe it was worn out bone stock stuff....
