ok, so i need some coilovers that would be good for drag racing.


anyone have any suggestions?


how are the megan coilovers?

 

megan coilovers have high spring rates but are great for the street.

I dont know the importance of having a stiff suspension for drag racing except to limit the amount that hp that is taken away during spring compression.

Here are some really stiff coil overs http://www.facebook.com/l.php?u=http...%3D992&h=d334e

 

megan is maybe nice for granny driving on the street..

if you want to do any king of racing, spend your money on something descent

 

you got to try them before you knock them. Just sayin.

 

I must be a granny driving on the street then there are other mods besides low spring rated coil overs that make your suspension stiffer

driving with too low of springs rates, doesn't that wear things out or add stress to the chassis or something??

lmao! no its the other way around. the more spring you have the more the car bends....

 

i had cuscos on my last fc that i used for daily driving and slight auto X'ing


but now ill have like 300-400whp and need some that ould be good for launching or drag racing...


what spring rate should i be lookign for?

 

have no experience myself, I would never mount anything like that on my car.
but several of my closest friends have used megan racing coilovers on different types of cars..
every single one of them failed within 2 years, they all upgraded to descent stuff

 

if you want to talk about "serious serious" setup, like real coilovers, not some wannabe bullshit, u are looking for at LEAST 3K a set. some can go even more.

Im not sure if they still make them for FC tho.

I use stock shock for my FC because I want to make it as stock as possible. but for my 8 that I track with, I use Ohlins DFV right now, and I consider them as "entry" level stuff, and prepare to rebuild them after every race or 2.

 

the road racing guys usually run 350-450 front and 225-300 rear.

 

even in the "affordable" range there is a lot of difference between coilovers

 

so a 12k spring rate is stiffer then a 6k spring rate?? i'm confused that isnt right.

Or are you saying the least stiffest spring will cause the car to bend? because that doesn't make sense either. the shock gets absorbed more in a bouncier spring therefor resulting in less chassis wear.

 

The higher the spring rate the stronger the spring/heavier.

So yes, 12k is much stiffer then 6k. Yes 6k will have more flex then the 12k springs. Adjusting the springs can help with the shock, i.e. rebound.

Megan, K2, D2 there all from the same company. I was going to purchase some Ksports, or Megan's but I found out that each shock does not have equal pressure in each shock from one to the other. I am just going to save and buy stance, as I haven't found a bad review about them for the price.

 

yes. 12K is stiffer than 6k

it doesn't make sense because you need to actually think about the physics involved. it might help to use the right terminology too.

is a bouncier spring softer or harder?

 

That's true.

Most if not all of the "so called" coilovers below 1K are complete crap, they perform worst than a lot of non-adjustable spring & shocks.

are those "affordable" ?

 

okay I had it backwards.

when spring come around I'm thinking about using my Megans up front and my Tokico HTS601R / RS*R spring combo in the rear. that should be interesting.

 

I don't drag race, but if I did...

I would use somewhat softer springs in the rear so I wasn't lifting the front end up. Stiffer up front.

 

when launching the weight gets transferred to the rear. with a softer spring setup in the rear wouldn't that help the rear end sag and the front lift?

so wouldnt you want stiffer in the rear I mean thats where all your weight goes ????????

 

I don't mean "squishy" soft. I mean enough give so that the rear doesn't lift the front during launch, but enough to keep it from bottoming the rear suspension out. If the rear is too stiff, you'll raise the front because there is not enough dampening.

How much HP are we talking about here?

 

^I would think you would want the weight on the rears since that's where our power is being put down. Better traction better holeshot. Idk either way tho I'm no pro

 

i understand now, hp and the weight of the vehicle or the amount of weight being transfered will determine how stiff the rears should be

 

i don't really know about drag racing, but yeah i think softer in the rear would be better, you want the weight to transfer to the rear tires, so it plants em

 

soft rear end with more power and sticky tires = grip.

 

jesus christ.... can someone jsut point me in the direction of a good set to use for drag racing....
