Koni/Redshift Coilovers

So, yes the Koni Sports will do away with the bouncy almost completely.

Thank you

I'm happy to say that we have been receiving good feedback on the simplification to our pre-order. And Excelerate now has it listed in their forum too. Please don't hesitate to call or email if you have any further questions.

Cheers,

Does this mean you pretty much averaged the shipping prices together and took a hit/took a hit for us depending on our location? =)

I REALLY wish i could order a set. Financial situation isn't looking too great right now.

[RedShiftChris]

Yeah, just averaged the shipping.

I am 90% sure I am going to hope on this...Just gotta see how my $$$ is...

For Koni Yellow/Eibach Pro package do you provide suggested spring rates for Si coupe or is it totally up to to me to figure out what exactly I need?

[Highrev1]

The eibach pro kit is their standad rates...If you get our coilovers we can suggest rates or you can choose your own, depending on the use of the car.

[RedShiftChris]

The Eibach spring rates are as follows.

Pro-kit # 4031.140:
front right 137-223 lbs/in
front left 137-223 lbs/in
rears 143-263 lbs/in

Sportline # 4.3140:
front right 126-223
front left 126-223
rears 131-263

They are progressive and only slightly higher than stock. Some people have found a little bit more drop in the front than advertised.. in the 1.5" front and 1.0" rear area... so the car gets a subtle rake forward relative to stock with the ProKit. I imagine the Sportline evens the Si out a it more because I'm guessing the weight of the Si's front has something to do with that rake change. The R18 engine cars (LX etc) have less weight in front; so the will drop less in front relative to the back. The Eibach part numbers are the same for both the K20 and R18 engine cars.

Both the ProKit and Sportline are essentially a small increase from stock performance in the spring rate department but a big improvement in ride height/center of gravity. And combined with the Koni Sport shocks, you'll have a really really nice daily driver that can run really fast times on track too.

The advice I've given a few people already is that the RedShift suspensions will all work better with a Progress rear swaybar and RedShift Reinforcement Brackets (all available through Excelerate Performance). This is no different than any suspension packages, but running a rear bar allows you to run lower rates in the back, and that allows for a great daily driver that can hit the track and be fast. And lastly, the #1 problem on the new Civic is the lack of camber adjustment in front; so I HIGHLY recommend a set of 2 aftermarket camber bolts for the front of the car (1 per side) to give yourself more like 1.1-1.5 degrees negative. The more the better. If this were a trailered track car, we'd be running around 3.0 degrees negative; so 1.5 deg is better than 1.1 deg, but the more camber you put in, the more your tires will wear on the inside. The harder you drive, the more camber you should put in because you may already have found that you tend to wear out the outside of the tire with so little camber. I would start with 1.25 degrees negative camber on any setup and see how that works. You'll be blown away with how much better your car handles at the limit with more camber!

Ingalls P/N 35420 = ± 1° adjustment (1 bolt per box at about $11 each)..... need to purchase 2 of these for 1 bolt per side. This is probably all you want to run on a daily driver unless you are ok with reduced tire life).
Ingalls P/N 81260 = ± 2° adjustment (2 bolts per box at about $22 each)......need to purchase 2 of these for 2 bolts per side. More performance but reduced tire wear. Only do this if you really care about the last tenth of a second at the track.

This info is now available on our Pre-Order Page at APRIL PRE-ORDER for your reference!

Thanks for the reply.

One thing I'm not clear on is if the Eibach kits are one configuration how can you suggest different rates for coilovers as Highrev suggested or lower rates in the back as you mention? What am I missing?

If I understand you, what I think you're missing is that the ProKit and Sportlines are progressive (start soft, end close to an OEM Si or LX rate) and are definitely street-biased rates and are not aggressive in any way, shape, or form.

Any decent custom setup will use linear rate springs and for a racer, the rates will be much higher as comfort takes a back seat to performance when building an autocross or road course toy.

Also, bigger sway bars (sway bars in general actually) act like torsion springs that work on the L > R side of the car. When going straight, the bar has no effect on ride or handling, but once the car is turned, the bar goes into tension and will act like an additional spring. If you got a basic RedShift setup with ProKits, the springs are relatively soft. But add a bigger bar, especially in the rear, and the car is going to think it has a much stiffer spring on it even though daily ride quality is hardly compromised.

thanks for making in a way were i could understand! so for daily driving the pro kit or sportlines with konis would be great? what is the difference between the yellows and reds?

its the adjustment of it the reds you have to take off and yellows are externally adjustable.

[Ksan]

Thanks a lot for an excellent explanation honda93, calling the buggers to place the order now!

[Sirbelch]

Also, the reds have less agressive valving than the yellows do. So the yellows will handle better but ride a little rougher.

Hey Chris or Greg,

Am I making commission off this or what?

if we already have springs, can we buy just the koni yellows? will it fit and how much if we can do it?

Yes, it's the first 2 entries in the list. :)
