16 gt
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.

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:

https://www.motortrend.com/cars/for...t-performance-pack-level-2-first-test-review/
https://www.caranddriver.com/review...-performance-pack-level-2-first-drive-review/

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

Could I steel this tread and ask something that I wonder could I use springs from MR car on a normal Suspension ? As can I use MR Mach 1 springs on PP1 shocks ?

Mike, what a fantastic picture. Have you submitted that to the "Photo of the Month" thread?
Järn, could you update the table that Mike posted with Mach 1 and GT500 data as well so we have all that info on same table ?
