Shop install bc racing coilover kit on my 2004 maxima n I'm having rough drive on hwy n city when I see hole or bumper rd my car hit really hard (boom noise) on hwy or city.Do I need to cut "bumper stop on strut/shock" n how can I turn knob soft/hard I see soft go left n hard go right but is doesn't said where I can put it to 0 on knob. Bec is said bc racing manual book shock ride turn to 8 n should I turn it to soft or hard way?

Is coilover kit never give us good ride?

Sorry for my bad English.

i recently installed the bc racing BR coilovers on my s13. i LOVE em. check the settings becouse mine were sent on almost hardest setting. how low are you?the bump stops are not on the strut/shock. you may need to cut them pending on how low you are. did you adjust the preload? ading preload is goin to change the rate of the spring and make it stiffer.

personally, these are way better than magans, the two types of tien that ive owned.

BC tech email me about cutting bumper stop n this what he said: In regard to the bumpstop no the bumpstops do not need to be cut as our kit is not a droop style kit.

So that mean I can't cut bumper stop?

ughh...i revised the way i was going to take this post

if you want a less harsh ride quality turn it to full soft, which is usually counter clockwise

most coilovers do not offer a nicer ride quality as the spring rate has been uped and the dampening is alot more aggressive

if the shop installed it, take it back to them and be like wth is this noise

nothing you can do about that

the only reason a cars suspension is confortable is that a soft dampening and alot of stroke on shock/strut

coilovers, even in their softest form, are more aggressive, so its impossible to achieve a comfy ride again without changing the springs and if you do that then what was the point in upgrading to coilovers in the first place

judging from the 20's...I bet you're running on really really low profile tires. coils + extremely low profile tires = harsh ride.

I have KTS coils in my s13 with 245/40/17 tires and the ride is nice. coils are always going to be aggressive. I guess you bought yourself into something that you don't know. good luck.

The car bottom out hard on bumply hwy or city. Anybody know how to adjuster preload? I got 02+altima kit for my 2004 maxima n I contacted bc n this what they siad to me

: Rohan
Yes the book manual says 02+ Altima which again is the same platform of the 04-06 maxima. The weight difference is minimal and much definitely stiffer than stock. The spring rates are a happy median between a 200lb difference in vehicle weight. Either way a stiffer spring is not going to get your car lower.

Are they right?

preload dosnt lower the car any more unless its in the front and you have the lower purch up as high as it will go, you adjust it by lowering the collar that the spring rests on but you dont want to droop the spring (not having the spring conected to the top hat)

honestly...your on 20" wheels and i dont really believe that you can bottom out, my 240 is on 16's and 15's with coilovers that are as low as they go and i dont even bottom out driving, you would run into rubbing issues way before you should be bottoming out,

i say

show us a picture of your coilover set up an the car and we can go from there

I went to different shop n they fix the issue I was having bottoming out. My dampering is set to 15 or 16 from hard(0). My car boucing when going to 0-40 mph. Y mycar boucing n I have not done alignment yet. I heard coilover are not made for big rim n they are made for light wheel 17" wheel. Is that true?

Check out my vid on bc racing coilover.

honestly i have no idea how you even bottom that thing out, that dosnt look that slammed

lowering a car and not having it aligned would make it pull in every which way that would make it suck on higher speeds, not coilovers that make it bad, think about it...you lower a car, the bigger the wheel the more issues your going to have with rubbing or turning

those tires arnt helping ride quality either

The coilovers should have very little to no pre-load on the spring. The spring should be firmly seated between the top perch and the spring seat with no vertical play what so ever but should be loose enough to be able to turn on its seat using only your hand. I find it hard to believe you're bottoming out a coilover before rubbing the wells with wheels as big as 20". Coilovers differ from traditional struts and lowering spring combos because the manufacture designs the springs and dampeners to work coherently at any setting or any height. Why would a company sell a product advertising versatility if it has to be modified to display its full potential? However, if you indeed managed to bottom out your coilovers, you must have hit something pretty hard. I’d be concerned with plausible chassis or product damage. Maybe I'm misinterpreting what you're saying, but before a reputable product is to blame, the user has to be questioned. My first assumptions would be if they were installed correctly. You said you brought them to a shop to install. This tells me you don’t have the time or space to install coilovers, or you physically are unable to install coilovers, or, you simply do not know how to install suspension components such as coilovers. I, Pandapants, am assuming the latter. If installed correctly, however, the only adjustments needed can be accomplished easily by the turn of a knob. Secondly, I would encourage an alignment; something that I predict will not be possible without aftermarket adjustable arms. Thirdly, if available, I would try the coilovers with stock wheels. Usually, bigger wheels have smaller tires. Tires with smaller sidewalls without a doubt display a harsher ride simply because of the lack of flex. I do not believe this is going to give you the results you’re looking for, but it’s worth saying when little description is given.
