Nice video. Looks very quick and the car seems tight.

 

Very nice, and nice prices on the sway bar kit, Mr. Strano. I found this thread looking for input on d spec settings for WSIR, and gained a lot of info! I think I ran with you last Aug., Slaya, with SV at BW. I was running a bone stock V6, at the time, and turning 2.26s(13CW), down to 2.18s after tires, GT brakes, and trutrac w/ 3.73s. Missin out on the roval, but I am sure we could get 5 of us stangs together for SV Daves group discount! Roval in Sept.?

 

Awesome info on this thread. Quick question Mr. Strano. I have an 07 GT 500 with stock suspension except for Eibach R1 Coilovers with these rates - Front: 350 lb/in. + 150 lb/in. tender spring
Rear: 250 lb/in. + helper spring. These coilovers are actually the kit for a GT but when I found them the price was right. They actually seem to feel very good and are not to harsh. I always wondered though if I need to change to a stiffer spring like the one that comes with the GT 500 specific kit.
Anyways back to my original question. With my nose heavy GT500 would your bars be a good choice.
I'm adding suspension stuff little by little as I find it. But I do plan on some Performance driving events.

 

350 front is pretty stiff... it's stiffer than what I run.

For your particular circumstance we'd run my front bar, but change to the alternate rear bar I have for the car, which is an adjustable 25mm instead of the 22mm to keep the balance in check from your 34/24 bars (solid and non-adjustable) because of your staggered setup and the spring rates you are running. The prices are the same for either rear bar. **PLEASE NOTE that I don't at this time list the 25mm rear bar on my site because it's generally what I consider to be too large in most circumstances, but folks tend to use the "bigger must be better" thinking when buying, so I do it on a case by case basis.

 

Hello again Sam. In regards to the springs, would you recommend a lower rate? Does the staggered tire size hurt the way my car handles? I'm glad I your bars are gonna work on my car. I plan on purchasing in a month or 2.
Oh yeah one more question that I hope you can answer (nobody I have asked has given me helpful info) In regards to settings on the R1 coilovers Should it be stiffer on the front end and softer on the back end or vice versa or something totally different? Thanks a lot for your time.

 

If there's going to be much street driving involved or many longer trips taken, you'll probably want to match the spring rates to the weight supported. There are a couple of fairly simple formulas that will give you the ride frequencies and the speed at which the car will naturally tend to NOT hobby-horse (like some of the newer cars have drawn a few complaints for doing under some circumstances).

One guideline is to set the rear ride frequency 10% or so higher than the front.

Another is to set the so-called "flat ride speed" to some speed that you commonly drive at. There's more room above that speed than below it before the ride deteriorates, so don't feel that you must set a flat ride speed to something like 120 mph just because you get up there once in a while. 50 - 80 mph might be a better range to work with.

Then use different or adjustable sta-bars to tune the understeer/oversteer balance to your liking.

I think the rates are ok we can tune the balance in with the bars easily.

As for the shock settings... that's a personal thing. Shocks change feel and response, not wheel rate like springs and bars do. And say setting 4 isn't the same damping on each end as the valving is different front to rear since the car is different front to rear. Most normally, yes the fronts get set to a relatively stiffer setting when comparing numbers, or turns of an adjuster, than the rear.

 

Hey, I do remember you at BW last year with the stock 6. You were baselining the car. I could be up for a run soon. Need some new tires first but am itching to get out there. Maybe October?

 

I designed and built a cammed throttle for a Can-Am car the first half pedal travel opened the throttle plates about 10% the remaining half travel opened the remaining 90%. 8 throttle plates and Lucus injection needed it.

 

The Vorshlag guys were complaining about handling problems on their 2011 Mustang auto-x car caused by the rapid throttle ramp on the Coyote.
