I can put Ps next to all the progressive rate springs but I don't have the data on how progressive they are until I put the springs on the load tester. _________________________ Kevin - Owner and Driver of Cars -

ryan12321 ryan12321 Sr Member Registered: 08/01/00 Posts: 1011 Loc: Athens/Duluth, GA	Rates for Skunk 2 coilovers are 400F/500R, i think the original skunkworks coilovers were 400/300 but not sure on that but I know the current ones are 400/500. I am pretty sure off the shelf GC are 325/250 for both civic and integras. _________________________ ryan12321@hotmail.com

clouds clouds Jr Poster Registered: 12/13/02 Posts: 158 Loc: CA	"Rates for Skunk 2 coilovers are 400F/500R" That doesn't look right. Spring rates are always higher up front to account for heavier weight. Handling must be interesting.

breakneckvtec breakneckvtec Post Master Sr Registered: 03/25/02 Posts: 3733 Loc: NJ	Yes, I think the rates are still 400f 300r, although I heard somewhere that the new ones are 500f and 350r, I dont know what mine are, maybe I will call up skunk2 and find out and post up what I find. All I know is that with the koni yellows I can come around a corner quite fast and the car doesnt lean at all, its amazing. _________________________ 06 Nissan Pathfinder SE 06 MS6 04 Seadoo GTX wake edition - GPS top speed 62.3 mph w/ no mods

SiLooksStock SiLooksStock Post Master Sr Registered: 04/17/00 Posts: 11113 Loc: Columbia, MO	In reply to: That doesn't look right. Spring rates are always higher up front to account for heavier weight. Handling must be interesting. No, they're not "always higher up front." A lot of people run higher rear rates for chassis balance. It's a common setup for road race cars. RealTime's ITR's use higher rear rates. You can look right at that chart Hondaman posted and see that the stock ITR springs are 250 linear front and 250 progressive rear. So, explain to me how you know "spring rates are always higher up front." _________________________

Huggy Huggy Post Master Supreme Registered: 11/01/99 Posts: 43048 Loc: Cincinnati, OH	Rich - don't you know the engine weighs more so the front springs have to be higher otherwise the car will sag - duh! (this is a joke for anyone that can't see that) Seriously, I've never seen an off-the-shelf spring setup run higher in the rear unless it's a custom order. I've heard the skunk2s are 500F/400R now but don't know for sure. I've also heard the Teg kits were 500/400 while the Civics were still 400/300. It's hard to say but if anyone does call skunk and find out they'll get a big Hondaman pat on the back . Side note - there's a lot of us who do/have run higher rates in the rear with great results. Actually if the rear springs aren't higher in rate you're only hurting your performance. Oh yeah - I got a new spring rate to add .

SiLooksStock SiLooksStock Post Master Sr Registered: 04/17/00 Posts: 11113 Loc: Columbia, MO	Yeah, seems like a lot of the kits run higher front rates to make it seem like the ride is smooth compared to the amount of body roll they eliminate. But body roll is your friend! It makes you look like you're going fast when you're not! _________________________

sarge sarge Sr Member Registered: 10/11/02 Posts: 1229 Loc: Okinawa, Japan	Hey Hondaman, is there anyway you can also post rebound and compression rates for stock and aftermarket shocks as well. Can you also post the recommended shock for each spring and coilover setup so that most people know what they are getting into in terms of ride and save some people buying shocks that are not compatible with some of the stiffer springs listed. Thank you. _________________________ 1992 R32 GTR

Huggy Huggy Post Master Supreme Registered: 11/01/99 Posts: 43048 Loc: Cincinnati, OH	Well I will not recommend shocks to a spring because that's not how it's done. As far as the damping plots, won't happen unless people start sending me stuff. I'll put any type of data up on this but I will not put recommendations, this post is truely a data collection tool only. _________________________ Kevin - Owner and Driver of Cars -

I remember a post a while ago with someone who ordered some CTR springs and I swear they were progressive in the rear (like ITRs). _________________________ Kevin - Owner and Driver of Cars -
