Post your spring rates and suspension setup

[DRFT_240sx]

Hey all , just wondering for your cars ff , fr , mr , rr or anything else... would be nice to share suspension ideas....for example what spring rates are u using for front and back and for what kinda car and power out put.....

in US for ff cars , they like to run high spring rates at the rear compared to the front like 7k/9k ...... to them it makes the car have a little oversteer but more to neutral feeling

but i belief on most japanese coilovers or springs , they mostly use higher rates on the front compared to the rear......

want to share ideas and opinion?

errr...if u haf higher spring rates at the rear, wouldnt tat make the car even more understeery...???.....

my fren....higher spring rate at the rear will create oversteer situation.

 

[spyderslr]

errr....i dunno lorr.....tats y its a question mah......

what kind of suspension setup is on your cars right now? sway bars? etc?

US dun have those uneven road in malaysia...

even our north south highway also __/\_/\/\__/\__/\/\__==__

if rear stiffer than front, ur rear might too sensitive on bumpy road...

imagine halfway u cornering then got uneven road... :O

well thats a good point what what i meant is track setup. like the setup you used on the race track not on the general public road.

to be honest US roads aint that good either they have those places where suddenly u have a bump like kesas as well.thats why usually people swap the suspension out one day prior to race events and put on race suspensions.

so lets just not focus on public road driving and more to setup on tracks shall we?

Spring rates depend on what kinda tires and what type of suspension.

Strut type will have less spring rate than double wishbone system due to the ratio. This is because strut types are more direct acting compared to double wishbone suspension.

Highly grippy tyres will work the suspension more than lower grip tires.

BTW I run 6kg front n 4kg rear on my AE86.

sounds logical ....... for those rates your running sounds more like the rates they have on some coilover here for FF , weird......

i am running 4k on the rear and 4 k on the front...currently using TITAN on my car..and running on SIMEX 14"....

My Dampers are TRD race dampers and the TRD spring are meant for high grip tyres. And since I'm on AD07 they work pretty well.

A Kelisa weight about 800kg all up. Running 4kg springs on all four corners on Simex tyres with short stroke dampers (on an already short-ish travel) sounds like you are pobably hardly getting any suspension movement.

hey faisal , seems like you race a lot to really know your suspension and tires well =)... do you join a lot of sanctioned events or weekend trackie?..... ;)

 

[faisal]

I'm just a wannabe racer. nothing more...

 

[DRFT_240sx]

lol humble is good......

now my setup seems a bit odd then .on my weekend track car which is a FF crx ....... i have 8k/6k ......seems a bit stiff? i'm running on azenis on 14 inch wheels..

CRX (EF series) uses double wishbone set up so the dampers and spring aren't "direct" acting as compared to Macpherson struts.

So the spring rates you run are relatively soft., for circuit driving that is.

Provided the tyres you run are highly grippy items, and your bodyshell/chassis is stiff enough and your dampers match your springs.

It's a combination. No point running stiff springs with "soggy" soft dampers and low grip tyres.
