Maybe Harvey won a Tour or a Pro out east?  I recognize the name but don't know him nor have met him.

You guys are all nuts.

Murray - stock front bar and giant rear bar.  Do it!  Not only does it work on an NC, but it worked great on my STS Civic  :o

Chris Harvey is Tire Rack's brand manager for Brakes & Suspension. Great guy. Chatted him up last summer prior to my Koni's purchase from Tire Rack for the FRS.

Duo of Fenter / Harvey placed...
2nd / 4th in CS at '14 Nationals
2nd / 3rd in CS at '15 Nationals
This was with Fenter's $$$ Penske's personally revalved, set up for Harvey's NC Miata

In 2016 Harvey alone placed 11th in CS. Behind 6 ND Miata's & 4 Twins

He seems to be a fairly consistent top 10 runner at nationals in BS, CS and STR over the last 15 years (that's as far back as the online SCCA results go)

Now, don't start being nice to me Brian, I wouldn't know how to handle it :P

I changed the sway bar setting from hole #2 to hole #5 (stiffest) today.  Damn, but that Karcepts FSB is one beautiful piece of work.  No need to jack up the front, I just turned the wheels enough to get easy access with one hand and a small ratcheting box end wrench.  Total time for change, perhaps 7 minutes.

This should be interesting, my best guess is it will increase the understear, but I've been wrong before.  8)

I also expect it to increase understeer, but if the severe mid-corner understeer is caused by bumpstop "shock", then the mid-corner understeer should be lesser and predictable, at the cost of more understeer in other parts of a corner.  If so, I have hopes that shock settings can ameliorate those areas, but they are unable to do anything about mid-corner issues.

At this point, all I/we have are conjectures, with no proof one way or the other.  Testing at a different setting should help clarify matters.

I hope it works for you. All I can say that when I had the big from bar on my car the understear was dreadful, and the worse it got the stiffer I made it. Probably has sometime to do with my driving style. All I can say is the re fitting of the stock front bar, and fitting the 17,5 RB the problem has gone away

Hope you find the results your looking for. Dont you just love R&D

The stiff sway bar setting turned out to be a mixed bag.  On Saturday, it handled well, without much understeer at all.  However, on Sunday, I had a waiting list for people wanting a ride in the car, and as soon as I had a passenger, it under-steered like a pig.  Run solo, and it was fine.  Go figure...

I have also developed a loud clunk when the suspension hits full travel.  I am taking it into the shop for analysis this Thursday.

I stopped on the scales on the way home, and the car weighs 1160 kg (2552 lbs) with 1/4 tank of fuel, me sitting in the car, and all the (heavy) timing gear in the trunk.

So nothing looked out of place in the suspension.  I got them to tighten up the sway bar clamps to prevent any sideways motion.  And now it squeaks when I drive it on the street :(

Getting a much more aggressive alignment this Friday -- toe out, here we come!
