Ive looked and cant seem to find them.
Does anyone know the FP GT350 lowering spring rates?

BMR now makes a true linear spring for the GT350 with spring rates of:
250 lb/in front linear
980 lb/in rear linear

I’d much rather run a linear spring but I’m also wanting to compare the two rates.

That's the FP springs.

Stock rates are attached on this message.
The 949 spring chart that includes M-5310 and M-5560, those are not ford performance springs. Those are oem springs rates.

The ford performance GT350/R springs are M-5300-W
These are the springs I’m interested in seeing rates of.

No, those are the correct individual part numbers. I just installed them on my car. The M-5300-W is the part number for the F/R set.

Here is the front.

I have the FP springs, but I’m more interested in the linear springs from bmr.
I have eibach front and rear sway bars and I’m curious on the bars matching with the FP & BMR springs.

Appears ford performance went with a soft rear spring ?

Now I’m curious of the bar rates.

Digging up old threads here...am I reading these graphs correctly with the following rates:

Ford Performance Springs (progressive)
Front: 250 lbs
Rear: 565 lbs

GT350 (linear)
Front: 216 lbs
Rear: 931 lbs

GT350R (linear)
Front: 264 lbs
Rear: 836 lbs

Does anyone have Eibach or BMR #'s?

BMR: 250 front, 980 rear, both linear rate. You'll find this combination is excellent.
