Just found out my Eibach drag-launch springs up front are rated 300 lbs then 465 on the second rate. And I thought it might be all the torque spinning the tires. I will be changing them for sure! I really need some 175lbs up front, anyone know what a 4cl.spring is?

Maybe check with NAPA they should maybe have a MOOG catalog to look up the 4 cylinder spring rates.

Good idea, i bet a used out one would be softer also. I got some used 4cl. coming in mail, if i dont like them , i am going to buy the moroso one and be done with it. I liked the idea a of proggessive spring to help from crashing down after launch. I would of never guessed Eibachs were rated that high till i put them in. Boy was that a mess with no engine in car,lol
