Thanks for all the help, and yes, road courses will require a different set up from drag strip. Having a slower rebound is better on the rear, because it will help prevent the rear tires from unloading as the car moves out from the start. One of the problems that can happen with the stock set up is the car squats a little and then the rebound is too much and the weight comes off the rear tires as it the front comes down and you get spin. So having that adjustability should help the launch.

Have to just try it out and see. So full clockwise up front and the rears maybe full counterclockwise on the passenger side and a quarter turn from full on the driver side.

My wife will be taking a long trip with me so probably end up full soft on that one - she always complained that my 2006 was too stiff for a rides over an hour, and now is used to her Lincoln ride.

I keep them on even settings on the rear, why are you thinking different settings? The only adjustment koni yellows offer is rebound damping so thats how fast they return to the top.

The more I think about it, with the tokico double adjustment that makes sense. With the rebound the only adjustment maybe setting both rear the same makes more sense just like the stock set up. At least for a start, and then make an adjustment from there. So front full soft for lift and weight transfer, and rear start with full firm and adjust to the point where the 60' suffers by too much rebound.

Full firm is ridiculously firm and probably undriveable, once the rear goes down or you hit a bump in the road it will probably be stuck down for like 30 seconds or more i would think, but you can try it.

You will find a good setting for your driving area after a few days of experimenting. I do think full soft on the front would be best for drag racing for maximum weight transfer.

Full firm on the rear would be for the drag strip only - not the street. Didn't make that clear.

I wonder if running more rebound in the left rear than in the right rear would help a car that rolls over a lot from engine torque reaction. Might be worth a try.

Incidentally, I dialed a lot out of my Konis for a ride up to a Mustang meet with the NJStangers group. The car did move around on the suspension more than I prefer, but there was a few miles of expansion-jointed concrete and my wife was along. At +3/8 front and only +1/8 rear you mostly just heard the joints, unless there was a noticeably raised asphalt patch. Adjusting all four is about a five minute drill once you've done it a couple of times, including the time it takes to open the hood and trunk.

I made a better adjusting tool than the plastic **** Koni ships with each pair from a short length of 1/8" steel strip. You do have to be more careful about overtorquing when you hit either stop because you've got tremendously more leverage. But setting 1/8 turn adjustments is about as easy as it gets, and you should feel the difference 1/8 turn makes.

A buddy of mine noticed that I was "bottoming out" (sparks from exhaust on big bumps) while driving on the turnpike when I had mine on full soft. Couldn't have that so I keep mine on 1/2 turn (all four corners) and it's stiffened up but not bad enough that you wouldn't enjoy the ride quality. I only have Steeda Sports too but the long tube headers/catted mid are likely the culprit for my low hanging exhaust issues.

I'm still toying with the drag strip setups. As you witnessed at Buckeye Brawl, my 60's weren't too stellar lol (1.9x) and I tried full soft up front, full hard rear. Though I don't think my culprit was necessarily the Konis and moreso the lack of drag radials, I don't believe it was optimal.

Thanks Josh, you coming to the Brawl this year? I don't think I will have the bottoming out issue. I still have the stock springs. With the front chin already low I can't lower this car.

Unfortunately I don't think I'll be able to make it this year. I'm moving to North Carolina this week for work so I won't feel comfortable asking for time off that close to my start date. If it were a Saturday, I'd be there no question. I'll be back next year for sure though.

I daily drive my 2011 with the yellows on full stiff. I don't think it's too stiff at all. It certainly doesn't stay down after the suspension compresses. The car could definitely use a stiffer shock/spring setup for the way I drive, so I'm planning on some coilovers after I stack up a few coins.

However, it should be noted that there is no right or wrong answer here, just personal preference.
