Mixing springs?

[Popo5ohh]

I currently have steeda ultralites with ford racing shocks and struts on my 16 gt. The rear sits a tad lower then i would like. Front is ok. Was thinking about putting bmr springs in rear to raise it up a tad. Will it mess with anything if i just change rears or shod i just swap all 4 to bmr and which ones? Ideal drop would be like 1" front and 3/4" rear with good ride quality.

Steeda 555 8250 Mustang Billet Rear Spring Spacer 3/8" (15-21)

Divide the amount of raising you want by two and pick your spacer thickness from that.

I have thicker spacer on already. They are the older model

I used a 1/4” rear spring spacer when I had Ultralites; it looked great:

You absolutely could just change the rear springs too; keep them linear like the fronts, and keep the ratios similar to the rates found on springs here:

Performance Package - Level 2 = 67% stiffer rear sway bar, 12% stiffer front sway bar,
20% stiffer front springs and 13% stiffer rear springs.

Model	Front Spring	Rear Spring	Average Ride Frequency
Non-PP	160	668	1.36
PP1	165	728	1.40
PP2	198	822	1.51
GT350 (2016-18)	194	914	1.53
GT350 (2019+)	211	857	1.53
GT350R	240	914	1.63

Steeda Minimum Drop & Sport Linear (These are the closest I find to the PP2...)
Front/Rear 200/800 with Average Ride Frequency = 1.50

Mike, what a fantastic picture. Have you submitted that to the "Photo of the Month" thread?

Thanks Järn! I submitted this one back in the fall of 2019; it did pretty well .
