johnc Posted March 20, 2008 Share Posted March 20, 2008 For those that run OEM size springs, here are the spring rates for the Tokico kits for the S30 and the S130: 240Z - Front (Progressive) 140 lb. in. effective rate. 240Z - Rear (Linear) 160 lb. in. 280Z - Front (Progressive) 185 lb. in. effective rate. 280Z - Rear (Linear) 200 lb. in. 280ZX - Front (Linear) 175 lb. in. 280ZX - Rear (Linear) 200 lb. in. A little tip, the 280Z springs can be used on the 240Z but you won't get any lowering benefit. You can cut 1/2 to 1 coil out of the 280Z springs to get the car a bit lower. This does increase the spring rate by some amount. Also, I can order individual springs from Tokico if you want to mix and match. Quote Link to comment Share on other sites More sharing options...
nbesheer Posted March 21, 2008 Share Posted March 21, 2008 Oh wow that is awesome information thanks. I was tired of telling people that I had "regular tokicos" Quote Link to comment Share on other sites More sharing options...
