Shocks and struts

Can anyone review the Koni's, Ford racing track ones and the Steeda Pro action? Which one is the stiffest? Best for track?

You have a PP?

Why not run some linear springs with the PP Mono rears and the GT350 Mono fronts?

That is what I am testing out on my PP car. ;)

I have a PP, so keep the rears and find GT350 fronts? but from where?

FR3Z-18124-U

Pretty sure that's it. You will want to confirm with whoever you order your Ford OEM parts from.

If & when you make it to our Pompano Beach location ... our tech team can cover that in detail with you!

If you would like, I can have our tech team call you directly - let me know.

Best Regards,

TJ

koni/steeda adjustables, can dial in settings for street and track

Would love to hear more about these results. I also have a pp get and want to get bmr sp080

Need the car to ride smooth or the wifey will complain

I'll be able to test it in a week or so. Both the monotube struts and the springs en route

Steeda pro action shocks can be tuned to 175 to 450lb wheel rates.

Also, according to our dyno graphs the Ford racing and standard GT350 fall within our dyno curves of the pro action adjustable.

Furthermore, damper tuning provides tuning for driving style and objectives.

One last note, if your're a hard core racer than the adjustable remote style dampers are the best.

Wheel rate is motion ratio times spring rate, right...

What would be the motion ratio for the s550 at stock alignment?

From another thread, wheel rate = spring rate * motion ratio ^2

Motion ratios approximately 98% for the front and 48% for the rear, so wheel rate = spring rate * 0.96 for the front and spring rate * 0.23 for the rear.

Wheel rate is the spring rate at the wheel example: front struts or coil overs are 1 to 1

The motion ratio in the rear is almost 4 to one, therefore a spring rate of a 1000lbs would have a wheel rate of approximately 250lbs

Hope this helps

Does the wheel rate range of 175-450 apply to struts too or is it only the shocks?

This.

Stock wheel rates for GT PP are 165 lb/in and 168 lb/in front and rear, respectively.

That motion ratio is also at stock ride height. It has migration through the wheel travel, which means lowered cars have a little bit different nominal motion ratio. Even more important though, is the fact that the roll center migration is pretty significant with ride height in the rear of this car. The rear RC drops a lot more than the front for the same amount of lowering, which will induce understeer without a roll stiffness increase in the rear. Even if you stiffen the rear, a lowered roll center will want to make the rear roll more and will make it less eager to turn into corners.

I like that BMR chose to only drop the rear 0.5" for this and aesthetic reasons.
