I already install KGMM and found out the ae92 KGMM spring is design for SUPERCHARGER use. While i install, the front is 3 finger, rear is 2 finger gap. why it like that. It because the front spring so strong it push up the front and the load goes to rear part spring.
My rims is 195/55/R15 TOYO tyre. so i install back the OEM spring with thick rubber seat and it become 3 finger at rear. Now is balance. KGMM spring rate for F 2.7~4.4 & R1.8~3.7, yet i found that front spring thicker than rear spring. So it's design for supercharger engine use. Supercharger engine is heavy than 4age 16v, 20v.
Optional i can choose to cut half round of the KGMM front if i wanna make it lower and replace back KGMM at rear and it will look balance. so it will be 2.5 front and 3 rear.
