Anyone using KW V1 Coilover's or BC Racing? I'm leaning towards the KW V1's with non-dampening adjustment, because the V2 and V3 are not available for my car. I'm only worried that i will find them a little too soft for my liking seeing as though they are pre-set to a neutral setting. The BC Racing on the other hand has dampening adjusting and seems like the nest best choice. Anyone using either of the two? Thanks inadvance for any input. |
I would 100% pick a matched set of springs/shocks over BC coils. As for the KW's, I'd say go for unless you really want it to be adjustable. What other options are there? Any chance you can get a ride with someone who has KW's on their car right now? |
Thats an idea, but not an available one. I'll most likely go w/ the KW's i think. But just worried i might find them a little too soft. |
What are you using the coilovers for? |

Mostly street, but maybe the track on rare occasions. Even on my old Tein SS, i found them not stiff enough for my personal liking on the stiffest setting, if i'm gonna spend upwards of 2k i wanna REALLY be happy with them thats all. thanks |
I can't speak for the Tein SS but for the KW V1, it should be valved to accommodate a range of spring rates but you will have to do your homework as to what will work within its range. I'm not a huge supporter of BC Racing but if you are simply going to crank the compression and rebound to full max in order to achieve the stiffness you want, you should be prepared replace them in 1 - 2 years. |
I've got BC Racing coilovers on my GTFour, the adjustment is noticeable from one extreme to the other but it doesn't seem to cover a very wide range. That said I got them with very stiff springs. |
please do not buy bc racing/jic/ksport/megan... they're all garbage , but they're awesomly cheap to just hang low, thats about all they're good at. they all have less than inch of travel (travel is one of the most important aspects of ride quality), have terrible valving (the most important aspect of ride quality), their many 3000 clicks of adjustment only adjust rebound, barely, typically linearly Entry Level koni sport with gc coilover kit Mid range kw v3/ ohlins dfv/ koni 8611/3011 double adjustable with gc coilover kit High end ohlins/penske/moton/ast/koni 2812/2817 high end only please. your friendly autocrosser |
Thanks. i have currently the Ground Control / Koni yellow setup on my car w/ NO custom spring rates, and i'm sick of them. Car doesn't perform great at all (i would expect better thats all) I'll most likely go with the KW V1, The V2 and V3 is not available for my car. |
What kind of springs are you running right now? If stock, it will be cushy and not as stiff to your liking. You may also want to look into having your suspension components freshened up i.e. bushings, control arms, end links etc. And which car is this? |
99-03 TL. Ground control coil sleeves (which uses an Eibach spring) and Koni Yellow shocks. |
Before you pour in a thousand or so into getting KWs, you may want give Eibach a call and see if they can recommend a higher spring rate that is compatible with the kit for your car. I'm confident if you tell them how the car is now and what you're looking for, they will have a product for you. |

I find it interesting that the GC/Koni setup isn't working for you. For my platform(MS3) we just finished development on a GC/Koni setup and the Eibach springs for it are supposed to be matched to the shocks. We can also specify heavier spring rates and the shocks would be valved to match the rates. And for more info on the KW, their philosophy is that spring rates don't matter, rather its the damping that matters. To the point that they don't usually disclose spring rates, but people have their best guesses as to what they might be. I do know that you can have the coilovers disassembled and put in your own springs at a custom rate, you can also order custom rates from them. I've heard really good things about people using Swift springs from Japan or Hyperco in their coils. |
The coilover kit for OPs car (Acura TL MY99-03) comes with basic performance springs that don't compromise daily driving. I can only assume OP drives a bit more spirited so the handling is in question where the springs may be too soft. He may be better off consulting with Eibach to see if they have a different spring rate that will work with his kit. EvoFire - Where does KW publish that spring rates don't matter but dampening does? I'm not questioning what you posted, but moreso if KW is actually serious about their claim. |

See the thing that is bothering me so much is the fact KW V1 do NOT come with dampening control. I wish i knew how soft/stiff they are before i buy them, YES BCRDUKES i do sometimes like to drive a little hard on rare occasions. My current susp rather sucks IMO when trying to hit a corner at a fun speed. And especially the rear has too much travel. garageFive wasn't very helpful in terms of different options i could have done ie. Spring rates, top hats. They used my stock top hats which are pretty much obliterated now, fuck sakes..lol. Also i'm running some wide wheels also 19x10 +30 in the rear, and plan on getting some wide squared setup of 19's in future, so i want minimal suspension travel. |

@E-Spec Do you know what dampening is for and what its purpose is? If not, you shouldn't factor it as a solution to your problem. Your Koni Yellows already have it. As I said before, call Eibach up. A bunch of your worries will be resolved when you speak to their techs - 1-800-507-2338. Garage 5 won't be able to help you. They aren't suspension specialists. |

Did you ever try turning your Koni's to full stiff? Or are they already full stiff? If you shorten the travel, the car will just behave unpredictably when you drive aggressively. |
You should not set any adjustable shock or coilover to full soft or stiff - it will shorten the lifespan of it and also not perform ideally. Travel is necessary in a proper suspension setup. I think in OPs case, the springs are simply not stiff enough for his driving style. That and it's not a new car; suspension components probably need to be refreshed. |
Koni Yellows are the best affordable off-the-shelf damper available and even their dampening adjustments are not linear. Dial locked on full stiff on one damper will probably mean 3/4 stiff dial locked on the other. Since you already have a good base to start with and it sounds like you're stancing your TL; high spring rates (probably at least 10-12k springs) and re-valved dampers are what you want as the Yellows are only rebound adjustable. You still want suspension travel so if the Yellows can't cut it whatever new coilover setup you use (obviously with shorter damper bodies) you'll still want higher spring rates and a re-valve. Dumped and stiff on a family sedan realize you are sacrificing a ton of handling for street use. |
your stanced 19x10's which probably have all kinds of fk'd up offset have messed with your scrub kpi and endless proper alignment settings are now thrown out the window and the fact your rear's are wider on a fwd car wtf? on top of that, you're likely mistaking too much rear travel with lack of spring rate and roll. im guessing you're dumped to the ground on unknown soft rates, and not running a rear sway bar *also, your stock hats are fine, what you're probably hearing is a clunking sound, this is a dead shock from being overly dumped / bottomed out repeatedly. get your yellows sent back to koni for warranty just dont tell them its been dumped. you need more travel, and more spring if u want to run that low. its not so much as your suspension that makes your car handle poorly, its your choice of form over function, and outright lack of suspension knowledge i have also driven on a number of vehicles with shocks that cost 1500$ a corner alone. and also on bc coils and the like the yellows are half decent from a cost performance point of view besides i have driven an ek sir with koni yellows, gc top hats and coils. it handles great in my opinion. i've driven on these on a mildly stc prepped ef civic, and set fastest time of day at the ubc enduro i've had them on an old crx si ive had in the past u dont have to take my opinion, i've won ubcscc slush index group, street touring group with vcmc, won the novice cup with vcmc, placed 2nd at packwood national tour, placed 3rd at canadian nationals in sts |
