Sure, the Subaru BRZ and Scion FR-S have different standard features, they both look a little bit different and are priced differently, but all of that doesn't effect performance and drivability of the car. We have heard that the FR-S has a higher rear spring rate then the BRZ to induce more oversteer for a different driving feel, but what are the actual numbers and what about the front spring rates? Well, here is the data.
Car: Front OE Spring Rate: Rear OE Spring Rate: Subaru BRZ 27 N/mm (153 lbs/in)
34 N/mm (195 lbs/in)
Scion FR-S 23 N/mm (131 lbs/in)
37 N/mm (211 lbs/in)
