Factory Coil Spring Rate

I want to say 625 but I will have to check on that. I know it has been posted here a few time. I think it was Greg that originally put it out there.

Your running 550s, dang. Great for flex but sucky on body roll.

Yeah, that's what scares me. 625?!?! I don't think so. My stock suspension feels incredibly soft to me. I know Penski is running 500# coils.

^+1
The 3" 500#s I'm running now feel way more stout than stock Nismo..

Their is no way the stock coil-overs are >500#

Geez, I hope not.

I remember some of the 650# (not 750#) coil spring users (Radflos) with aftermarket bumpers (Shrockworks) were complaining that they were still too stiff.

stock spring rate is 500lbs.

^then it's either all in my head or the 2.5s are just better...


Muh head ain't quite right tho'.. :laugh:

your coil rate is part of the equation. You still have valving and the amount of presure in the shock. Not to mention the shock design it's self.. Bills and stock shocks are made spread the load over an infinate amount of travel. So what ends up happing is you hit the end of the shock travel and it still has a load on it, and it bounces. Were when you buy a good after market shock and they are tuned right that force is spread over the distance of that shock travel making it harder to bottom out.

there is a ride quality deference between a 2 inch and 2.5 inch shock.

500#?! wow, thanks mike.
