which one has a stiffer spring rate?i want a oem quality ride but would like if my springs were a bit stiffer.i have a ap1 btw

 

ap1

 

Ya, AP1 is suppose to be more "pure" of a sports car.

 

ap2 CR

 

I guess the OP didn't take this option into consideration.

 

ap1... I think the CR is the same or really close to the AP1

 

ap1 is indeed a more "pure" of a sports car.the feel of it is much better,but lets not get into this.
i didnt consider the cr but edmunds say that the springs are stiffer than than the 08 by 38% front and 17% rear.the damping rates are up by 50% front and 32% rear.the cr suspension seems much more appealing.where can i find some?

 

you know they have the same spring rate, right?

 

in the rear they are, but the CR is WAY WAY WAY stiffer up front.

 

www.thehardtopguy.com

you can find some CR suspension there.

 

 

from everything ive read or heard, AP1 spring rates are the same as the CR, perhaps i was misinformed

 

thanks for the link!does anybody know how the cr rides compared to coilovers that are around 1000$?anyone driven a cr?

 

seems to happen alot on HT

 

thats a broad statement. for 1k you can have shitty ride quality or decent ride quality.

to answer your question CR suspension should only be a little different from your ap1 but in a better way. If you dont reaserch your coilovers and cheap out, you can actually handle worse than a oem cr springs.

from the sound of it OP, it seems that you want to make your car handle better but not daily drive stiff suspension. i recomend just getting eibach pro kit until you decide to step up to coilovers. they have similar spring rates to the CR, lowers your car 1" and is still smooth for DD. and ive seen them go for 100$ used.

 

I can't find any rates online to compare CR with the ap1/ ap2. For the most part online is stating the fronts are stiffer, but they are also stating they are stiffer due to the thicker sway bar as well as the possibility of different spring rates.

 

i have a cr and a base model 07. cr is much rougher then the base. i put ap1 wheels on the cr to soften the ride a bit, as well as pulling a 1000# trailer, but you def know you are in a CR.

00-01 - Fr: 218(3.9) - Rr: 291(5.2)
02-03 - Fr: 240(4.3) - Rr: 230(4.1) Guestimate
2004 - 2007
If calculated against 02-03 rates
Fr: 256(4.57) - Rr: 207(3.7) (guestimate)
2005 - 2008
Fr: 275 (6.7) - Rr: 226 (5.8)
2008 CR
Fr: 377 (8.6) - Rr: 264 (6.4)

this is common data found online, BUT one of my competitors has tested the front springs and found his CR were a touch over 400#.

 

you are exactly right!i want it to handle nice but not completely untolerable as a daily.sooner or later,i will go with coilovers so i wont buy springs for now and go through the trouble of swaping them and getting an alignment.im just going to go with a nice set of coilovers for a 1k.
im assuming i will have to buy cr shocks and springs,and that the ap1 shocks cant handle the cr springs.the complete cr suspension kit in the link is over 1000.

 

i am very confused between aftermarket or cr now!

 

no, oem CR suspension is non adjustable spring/shock combo. but dont dare pay 1k for them. theres a reason why you dont see base models s2k's upgrading to CR shock/spring combo. your better off going with koni/GC combo.

 

Rodney really knows his ****.

 

thanks for the info!i think im going to go with aftermarket though,1000 for oem coils is not worth it to me.

 

yep!i might go with BCs,screw comfort!roads around orlando are pretty smooth anyways!haha

 

the rates above have been discredited, based on the suspension test done by SCC. the now accepted numbers are:

AP1 [00-01]: 218 (3.9 kg/mm) 291 (5.2 kg/mm) ( Published )
AP1 [02-03]: 249 (4.4 kg/mm) 306 (5.46 kg/mm) (From SCC, also note that the UK Press release stated firmer springs )
AP2 [04-07]: 266 (4.75 kg/mm) 275 (4.91 kg/mm) ( 7% stiffer Fr, 10% lower Rr, compared to prev)
AP2 [08 --]: 284 (5.07 kg/mm) 299 (5.33 kg/mm) ( 7% stiffer Fr, 9% Stiffer Rr, compared to prev)
CR [08 --]: 389 (7 kg/mm) 349 (6.25 kg/mm) ( 37% Stiffer Fr, 17% Stiffer Rr, compared to prev)
(SCC tested 392 lb/in (7.00 kg/mm) 342 lb/in (6.22 kg/mm) for the CR)

 

They increased the spring rates from '07 to '08 some 20lbs/in F&R huh? I checked the part numbers for the springs at www.hondaautomotiveparts.com and they are indeed different (between '07 and '08 base and of course the CR).
