Hi, I'm looking around for springs. But looking around, I find most of the aftermarket springs are softer than OEM ones in the rear, I'm looking to keep the same spring rate ratio with more stiffness. I track the car about once to twice a month.

Stock = 5.7kg Front, 7.6 Rear.

Most aftermarket springs have stiffer rates in the front than OEM and softer rate in the back than OEM. I'm looking to have stiffer all around for track. Also preferably linear rates.. speaking of which, are OEM linear or progressive? I'm assuming linear since I get a headache if I go over too many potholes.

I found Espelir Active GT to be the only springs that has stiffer rates than the OEM ones with 6.9F and 9.2R, and was set on buying then later on I found out that they were progressive.

Any suggestions? Thanks!

 

... no one? Dont tell me coilovers are the only way...

Or maybe I'll just get Espelir if the stock springs are progressive...

 

I remember reading somewhere that Nismo T2 springs are really stiff, maybe you should check it out.

 

I've got a set of NISMO T2 springs for sale. PM if interested.

I just moved down to a 500 (Truechoice Koni coil-over conversion) and OEM 4.5 427 rear.
