Spring Length?


Recommended Posts

I'm trying to decide on a spring length for my 280z so I can order a coilover kit. I am welding in the TechnoTuningToy camber plates. I'm planning on not sectioning the struts. I'm going with 250 front / 275 rear springs.

 

I plan on running a 25.6" tire front and rear on the street. On the track I plan on running upto a 27" tall tire.

 

I was thinking I'd do a 10" spring on the front and a 8" spring on the rear for more clearance on the back.

 

Would I be ok with these spring lengths? Should I run a 10" rear spring?

 

Regards,

Justin

Justin,

 

10's are what I see most often (F&R). I've also used 10's exclusively on my cars. Never did the math but, before installing 8's, I'd want to make sure they didn't coil bind... 6" stroke with an 8" spring sounds like a problem.

 

You're welcome to stop by and have a look at my car.

Ron nailed it. You need to make sure the coils don't bind. Eibach has their spring specs in their catalog which you can download here: http://eibach.com/eibach/img/ers-catalog-2004.pdf

 

I tried to find this info for Hyperco and had a tough time. Eventually I found it but I can't remember where...
