Hey does anybody know who makes some stiffening springs for a S13, 91-93, i want about 6.0 in front, lil less in the back, the best ive found is 5.0. Any help would be appreciated, plz post links. Thnx!

 

6" what? 6" drop, 6" from the ground to the bumper?

 

i think he means 6kg/mm spring rate...which is about 336ish lbs/inch

Those are the only ones I know about...and I have no clue how you are going to get them here.

They are the S21 Racing springs

 

Yea i mean 6.0 stiffening springs. Got a site thats in English? I got friends in Japan so getting them over will be NO problem My bros g/f is Japanese and her family lives in Japan , hahahaha!! I dont want progessive springs either, i heard they affect ur drift wen the shift from one spring rate to another.

 

Use bablefish.

Don't know if they are progressive or not, and I don't know what shock will take the stiffness of it well.

 

If AGX's can't take that spring rate, no way will stockers handle them.

 

Of course stockers won't handle it, but not sure if the AGX's can either.

 

Konis maybe, not AGXs. Didnt KYB warn against using RSR race springs on them? and those are like 5kgm.

 

Koni's can handle it if you get the Koni's valved right for the spring rate (which you can do when you order the Koni's). AGX's don't seem to hold up with springs stiffer than around 4kgf/mm
