Alright im looking at the 2 way adjustable ksport pro circuit setup. car will is a teg that really wont be street driven. I want to compete in time attack in the modified class. car setup will look some what like this. front splitter,apr gt200 spoiler, gutted close to rules on modified class, 225 r comps, cage, and around 350-400 whp...

My question is spring rates really... my old teg had 10k-8k setup and was nice for the street but was not even close to feeling flat with 302whp, full interior and bracing w/ 22mmw/ asr sub frame.

I did like the way it handled just need more spring rate... well at least i think. if you have some tips or suggestions or different idea please talk away

 

Honestly K-Sports aren't the best coilover setup out there, In my opinion i think they are horrible.

I'd look into Koni Setup, PIC's, Apexi N1's, or Teins. You are also leaving out what kind of car you have,

I'm assuming these are for an Integra, 10k/8k is perfectly suitable for the track. But if you want something aggressive i'd suggest 12k/14k. I'd highly suggest tracking the car with the setup you have now and go from there.

This thread might get locked but i figure i'd chime in before Adam does

 

Normally Dil would be right, and I'd lock this with a quickness (I don't even know how many spring rate threads exist here...). BUT, you have one potentially interesting thing, and that is the amount of power you'll be putting down. That (to me) changes things a little, as you're going to have issues putting it to the ground no matter what, and the typical high Honda rates might work against that even more. I believe Claude has a higher-powered turbo ITR, so he might be able to chime in with suggestions.

For your shock choice, K-sports are garden-variety Taiwanese generic stuff, really not impressive from a performance standpoint. If you're throwing money and effort at a serious competitive car, I'd look elsewhere.

 

Legoman don could chime in here too as he has a very similar set up to what the op is building.

 

I normally am against k sport or any others like them, but the uk people swear by them and is on some of the fastest TA cars over there including a 22b named the "gobstopper" that had no money spared in the build.

I like the PIC but they are single adj but i still didnt cancel them out and not against a nice set of single adj that will perform for me. and to me apex i seems to be the same Taiwanese generic stuff made. Teins that i had on my nsx that i just sold didnt impress me that much compared to something cheaper...

Here are the ones im looking at

i would love to hear from the turbo itr guys

 

I'd start with a minimum of looking at the Koni 8041-RACE. Its a single adjustable (rebound) shock that is really really good. And it is durable. Priced around $1,200 for just the shocks

Next look at the koni 3011. It is a double adjustable (external top adjustment for rebound, and a button the body and turning the entire shaft for high speed compression ie bumps and such on the track). These are around $2000 for the shocks and sleeves.

Also in this price range is are the JRZ single (~$1700) and double adjustable (~$2300) shocks.

The next step up would be the JRZ RS pro/Moton club sport double adjustable RR shocks. (~$3,700).

Around this performance/price is also the koni 2812 (double adjustable from the top of the shock via two adjustment *****) These are around ~$3960.

And then you get into the big dollar/difficult to use tune stuff.

Moton/JRZ 3way (high and low speed compression and Rebound. These are right around ~$6,800.

 

ok jrz has my attention who has the best pricing?

 

You aren't going to get "killer deals" or one store slashing there prices like you find with the typical import crowed store.

JRZ/moton/penske/ect all have there prices set, if some one is slashing the prices they wont be selling them for long.

Andrie at www.prima-racing.com sells JRZ stuff, and is knowledgeable about the products. I'd shoot him an email.

 

I think Apexi N1's and Teins are right in the same ball park as K-sports with the Teins maybe slightly better. When looked at on the dyno, all the JDM coilovers were pretty much junk. K-sports aren't even worth the time and effort to dyno it seems, I still haven't seen any serious reviews on those but what I have seen is K-sports mostly being used to lower a car and that's it. I'd stick to what everyone has been saying, just my $0.02.

 

I never asked for the killer deal or slashing prices... just who has the best pricing. they dont even list prices on there web site.

sorry as for car integra gsr

 

Holy ****, $4000 for those K-sports? You can get some very serious hardware for that price, and not worry about potential quality problems.

One note on adjustability: if you don't know much about driving on track, or setting up a track/race car, the multi-adjustable units are probably going to be more grief than anything else. It's easy to do it wrong with those. Also, just because a shock company is marketing a shock as double-adjustable does not mean the results are consistent shock to shock, or that the quality is there. I know even that doesn't necessarily matter (who was saying the thing about Motons not being consistent one to the next, so kind of having to set each shock individually?), but it's something to keep in mind when tuning the chassis.

 

They will be the same everywhere.

 

Thanks stinky! as far as track time im not saying im pro or anything but i have been doing this more real competitive stuff for 3 years now but i still am learning.

Back on topic this was never meant to be a "which is better" only a what spring rates would suit my setup and what i have liked in the past to only guide me in a some what right direction

as far as price the ksports only had me because of price (2500 shipped) and the wins on cars in the uk

 

Id be very interested in hearing where you got those prices from??

I was quoted $3800 for JRZ singles without springs or top mounts (although this was for an 02 Civic/RSX)... but the price listing shows most singles in the $3-4k range... with doubles being $5-6.5k.

 

^^^ see and thats why the ksports grabbed my attention was the 2k range verses 3-7k

 

If you like the way it handled then what does it matter if pitches and dives a bit under acceleration?

I think the Kontrol Pros (with beefed up springs) or the Version RR would probably accomplish what you're looking for.

 

I am talking about the JRZ RS , and JRZ RS Pro respectively. Double checking on pricing now though...

You are talking about the JRZ Professional Race series RR single, and double adjustable shocks.

The Strut version are always more expensive. From $1000 to $1400 more expensive then the dampers.

 

What are you basing your opinion off of?

 

LOL, where do you guys get this stuff from?

 

Tage Evanson's time trial / time attack Civic runs K-Sport Kontrols. He seems to like them enough to run them at NASA Nationals this year....
http://ksportusa.blogspot.com/2009/0...nationals.html
He's in the 300's on whp, has the front splitter, rear wing, gutted, cage...very similar platform to what you mentioned.


We went to Buttonwillow this past weekend and he set the track record in TTS on Saturday and the track record in TTU on Sunday. If you're not familiar with the classing structure of NASA's TT series, there are about 9 classes total, those 2 classes that he competed in are the 3rd and 2nd fastest classes overall, respectively.

Not bad for a garden variety Taiwanese generic suspension setup.

 

probably from the past experiences like this and posts like this fully admitting to it

And it is understandable.

Even the highest quality units, with limited issues (blown shocks), all still have a very very limited adjustment range. This is by the design, the adjustment they use. Which is fine, if you have access to cheap and quick, rebuilds or the knowledge and parts to re-build the shocks yourself.

But for the vast majority (of armatures and a good portion of pros) having a wide adjustment range is very helpful.

 

Playing devils advocate.....if I shyed away from every company who I've heard an internet horror story about I think my car would be 100% stock (I've heard horror stories about Honda parts too though, LOL, so where does that land me?). :p

Without knowing all the facts its tough to point the finger at companies like K-Sport, Skunk2 (with their cams), Blox (LCAs), etc..

The 2nd half of that post:

 

Very true, all companies have a part here or there that is bad.

You missed the point of me quoting what i quoted, i didn't want to cut any of the story out so i quoted the inter post.

There reputation is based on history. And that in which Tage admits has flaws.

That is all i was point out by that quote.

 

It sounds like Tage has an involvement with K-sport as well, much like the "gooby" or whatever car may as well. Sponsorship-type relationships don't tend to lend the same credence to a reputation as someone non-biased. Maybe that's legit, maybe not, I have no idea. Sometimes horror stories are well-deserved (early Omnipower shocks as one example, or JIC FLT-A2s).

My opinion is based on cars I've driven, friends who have tried using their customer service, and shock dynos I've seen. One guy liking them (or two, if you're the second) won't change that easily. That's great if they're picking themselves up, but up till now they have done nothing to impress me.

As far as class records go, they don't mean squat by themselves. I could hold the class record in anything (be it the fastest or slowest class) if my competition was non-existent or sucked. I'm not saying Tage's accomplishment isn't worthwhile, just that the statement alone is with nothing to back it up.

 

I do not know why K-Sport has such a bad reputation there in the USA.
Well, they are a relatively new "brand" and new brands learn from mistakes.

Here in Germany and Switzerland there a lot og high HP cars that run K-sport on theire circle track cars. I do not know of any major problems. Not more or less than other very famous brands here.
