NEWEST megan racing coilovers 12/10 springs...

[SR22DET]

hey i was wondering what are the thoughts on the newest megan racing coilovers with the 12/10 spring rates, do you guys think they are waaaayy too much for the "regular" street use because i talked to my friend and he said i could get them if i hate my kidneys... but i like them and i dont want to lose them because i'm about to get the 8/6 ones but if 12/10 isnt overkill i would get those

thanks for your time

The 8/6 springs are stiff enough for street use, sometimes it's a little too stiff. 12/10 = blood in your pee.An uncle of one of my friends had that happen to him after he bought an M3. Of course years of drinking/smoking probably didnt help his kidneys either, but you get the point

[SmithSR]

12/10 is not for regular road going use.8/6 really shouldn't be either.Both are bone jarring.

[nismofly]

i think thats about as high as it gets before you have to start ordering specific springs

you can get up to like 30 kg/mm swift springs for zeal coilovers...

[SmithSR]

Well my car has 9/7 coilovers and they are pathetic and have (along with all other suspension mods) made the ride so bad and too harsh.

A suspension NEEDS to travel. We are not race drivers and we do not have race cars.

Tires are too easily overloaded and traction decreases and you crash.

[Bronze MFP]

I think the 5/4 rates on my old HKS springs were a nice compromise. the 3/2 on the tein springs before that seemed too soggy, and 8/6 in my kts coilovers rattles my fillings on some of the less maintained roads around here. I think I might have kept the HKS springs if i could have found a decent damper to go with them. Koni's are nice, but why do they make the install and rear adjustment such a chore???

[nismofly]

Smith on a race only car with a set of say, Toyo RA-1s, what would you say is still max for spring rates

im thinking about some of the NASA pro racers ive talked to, a few are running up in like the 16 - 18 kg/mm range but almost everyone runs at least a 12 or more

were talking sentras, civics, integras, etc...that have coilovers and the like but still the same suspension overall, like a highly modified, very stiff street car

[SmithSR]

7/5!

[nismofly]

i seriously am going to go ask these people that are running 2 or 3 times that why they run such high spring rates

[SR22DET]

thanks a lot for the unput i didnt really want to buy a coilover that would make the ride too harsh i just want it harsh enough so my car doesnt tip over on corners and for drifting when i finally get money to convert it to a 5 speed .... when i turn i can feel the body lean like no other and it scares me cuz i feel like im in a jeep

[veilside180sx]

Sway bars and coilovers will fix that.

[SR22DET]

i'm getting coilovers and then probably suspension techniques sways cuz i get a discount on them

[turtl631]

Okay, two things. First, the chances of the MR coilovers being valved properly for such high rates are incredibly low. Secondly, you will never need rates that high in a 240SX unless you are racing it in a series, and in that case you won't be asking us about this on the internet. Ugh, actualy its 3 things Cars have different suspension geometries. 12k springs don't translate to 12k wheel rates necessarily. Other cars might have the spring located more inboard from the hub, requiring higher rates due to the lower lever arm to create the same torque. I'm sure Q45tech can chime in with some equations and calculations to show us exactly how this works out in different cars

[nismofly]

^^^ i guess id never thought of it that way...

maybe is that why some honda challenge civics and integras are running like 18 - 20 kg/mm springs?

[turtl631]

Perhaps. You'll notice that rates about 10 kg/mm are far more common wtih honda coilovers. Yet they weigh 400-600 lbs less than S chassis cars usually, which means that those rates are proportionally even higher. Something else must be at work, I blame geometry.

[InsanityInc]

Well, you've got to figure that FF cars also usually run much higher front rates to compensate for the fact that they're driving and turning with the same wheels.

[veilside180sx]

Well actually most high end race FF cars run higher rear rates than front. Take all of Peter Cunningham's cars for instance he runs stiffer in back on all of his. So do a lot of the guys in the SE-R cup.

[sleepyRPS13]

i think those are perfect spring rates for me.

[nismofly]

indeed, i look at it as the opposite of us, were both running the softer rates at the powered end

[LiU]

those hondas have double A suspension and wheel rates are what that matter... besides, 12/10 is way too high for the street, and probably too high for most double duty cars that see track time unless you're using r compounds.

[veilside180sx]

I agree with SR Smith, the stiffest I would ever go on a street car is 7/5. Even that is quite stiff on the everday street.

[nismofly]

he said thats even high enough for a full race car

[SmithSR]

My reasoning is, who here has a full race car?Not me.I've decided for my car that 9/7 spring rates are absurd.The suspension has way too little travel.The tires themselves actually flex when I try to jounce the suspension when I align the car.The tires are severely overloaded in hard corners, leading me to believe that if I had a tire with less grip than an R compound, I'd be sliding and crashing.Load transfer in cornering is a joke. Load instantly shifts to the outside tires, then the tires wash out immediately.I'd rather enjoy the car on early weekend drives on empty roads. Hard to enjoy a drive when you're literally bouncing down the road.None of this drift spec nonsense for me.

[Jookmasta]

i dont run coilovers but my spring rates are 6/5 kgmm. i can say that this spring rate is beautiful for daily driving as it doesnt give you the mushy ride like eibachs but you arent subtracting body roll totally from the equation. 12/10 rates are just ridiculous for all of the reasons mentioned in the previous posts. you really will hate yourself as you will be bruising things should you encounter a road that looks like it was imported from a third world country. also remember that your tires will determine how ur car will also ride. my suggestion is to try and ride in as many 240s with varying spring rates so you can see which one would suit u best. the coilover upgrade will definitely make your car handle better but remember that we do drive on roads and not on the track. (at least for the most part)

[sleepyRPS13]

har har har

[JT$240]

I'ld also like to say that 9/7 is way to stiff if you use it on the street as a daily driver. Sometimes I hit bumps and it literally feels like I'm going to start flying, I need to get a hold of some 5 springs and see how the 7/5 combo feels.

[sleepyRPS13]

i have 7/5 and its too soft for me.

[BuLLeTdrift]

I'm w/ him ^. i think 7/5 would be too soft for me. I previously owned the 8/6 MR coilovers and i loved it. Those, strut bars, tie bar was perfect for me. I wondered how it would be w/ higher spring rates.

I can't see how you guys say anything over 7/5 is too stiff. with 8/6 i just softened the dampers when i wanted to chill, and when i went out to drift i just stiffened them. Dont you guys adjust that when needed? I can't see how 8/6 is newhere near too harsh. I live where roads are very bumpy and i never complained once. If your considering 8/6 you shouldn't be disapointed unless you just want the look. If so, get some ebay coilovers.

I'm gonna get another 240 I was planning on getting the track series coilovers. But my only questions are:

1. Will the super stiffness in the front cuz understeer cuz its so stiff?2. If so, cant i just adjust the damper to fix that? cuz i think so0o3. Are they designed to maintain the high spring rates braking under regular drift abuse?

[veilside180sx]

Personally I think if your damper rates are set up for the vehicle and spring rates that you shouldn't be adjusting them all the time.

[BuLLeTdrift]

If you got adjustable coilovers, might as well use them. You sure pay enuff for em'.
