I am looking for the specs of All Valve Prings that are made for the SR

Well at least the most


I have found 6 Diffrtent velve springs but only got some SPecs on 2 of them :D

Maybe this could ba another good tech thread for someone looking for SR Valve psrings :D

Here is What I have so far :D


Greddy - No Specs
Tomei (2 Types) A & B - A = single Spring / B = Dual Spring
HKS - No Specs
Toda - No Specs
Peak Performance - 250lbs
Ferrea - 255lbs
Apex'I - Dual Spring, Good To 8k rpm (I think Rhombus Tuning has taken them to 8750 rpm but w/ There built head IDK - But there head is only P&P)
