What Rear Springs Do You Have?

[steve200b]

Hi

I need to stop the rear from sitting on the bump stops when I stand on the fast pedal. I have low king springs with koni adjustable shocks, i have replaced all the rear bushes and it still squats all the way. I want the car for traction not drifting.

Any recommendations would be appreciated

Thanks

What adjustment did you put on the Konis when you installed them? Ummmm ............ I guess we are talking about Koni RED/ORANGE eh???

They are the red/orange ones and they are about 1/2 a turn passed half way.

It squats cause on purpose it causes grip!

ask any drifter firm in the rear is best for sliding

bump stops is to much i admit.. to reduce it you need a higher spring rate.. but lets not forget king springs are purely cosmetic, get some Pedders coils or something Japanese, take a caliper and measure the size of the steel the spring is made of that is the only real to be sure the spring is any harder.

but dont go over board it needs to remain softish for grip

Did you fully depress the piston to engage the valve before turning & did you take it anti clockwise to stop beforehand?

For a start Pedders coils are SH!T, Pedders coils are designed for the MASS market and nothing else. Ring Pedders and ask for the spring rates and they will tell you what you want to know which does not resemble the truth in ANY way. Pedders springs are for mister Joe average that wants a stiffer ride because he does a lot of towing or his ride height has dropped/sagged and needs it to be raised and doesn't care to hoots if it's right or wrong. I have tested them out with a set of springs off an N12 Pulsar, I quoted part numbers to the guy on the end of the phone and he asked me what spring rates I was looking for and he told me the rates I wanted were very similar to what the Pedders springs were, but he did not know I had them measured before I contacted him for the information and what he was telling me on the phone was all lies and that is for sure NO BULL?????????????

King Springs will tell you the spring rates and the entire suspension can be calculated from there, and anything Japanese is by far to stiff for Australian Roads. As a general rule of thumb with Japanese springs is use the rears on the front and get new rears made to order.

Remember the conditions in Japan, our race tracks would resemble their roads and their race tracks are like glass in comparison to ours and therefore the springs that come here from Japan are far to stiff.

Factory suspension design is all about a comfortable ride and the vehicle carrying passengers and luggage in the boot and absolutely nothing about handling. The fact that a factory designed suspension might also handle fairly well is pure luck.

As I said before springs simply hold the body up and that's about as much as they do. Springs on there own do SFA no matter who makes them. Take the shocks/dampers away and your car is going to bounce continually and never stop and that is a physical fact.

Just because you work for Pedders doesn't say you know what your talking about I'm sorry to say. When you next have time, take a spring off the shelf and go get it measured, then ring Pedders as a normal person and not through the internal network, tell the guy on the phone you want a spring rate 50 or 60lb/in higher than what you have in your hand and he will tell you what you have in your hand is very close to what you want and that is a FACT!

I personally would not use anything Pedders makes for the mass market arena.

I use King springs only for convenience on my road cars, but my track car has custom made springs by ALSPRINGS at Liverpool on the coilovers and the rates are conducive with the front to rear weight balance of my DR.

Suspension is a whole lot more than springs alone and the fix for this guy is in the dampers, not nothing to do with spring rates being to low, because the dampers control the springs, but I guess that's a bit outside the knowledge base huh?

If he has adjusted the dampers correctly, the only other possibilities are that the dampers and or the springs have failed and should be returned if at all possible for replacement.

I had an MR30 L24ET Hatch a few years back and I had 200lb/in rear springs (Jumbos) and red Koni's 1.50 turns from start and under hard acceleration it would sit down a bit for sure, but it never bottomed out, not once and in my MX83 V8 Cressida with King Low's & Koni's with 1.25 turns from start never bottomed out either, not even coming off the line at WSID @ 2200rpm on the way to a 14.709 run.

Rob Ward in Adelaide has King Low's & Koni's, or Bilstein in his 205rwkw MR30 L26ET sedan and his car doesn't bottom out under hard acceleration either.

Stock C210 susp, would squat heaps, never to bumpstops though.

current HSD S13 rear coilovers 6kg

thanks for the info guys i will check the shock setting first.

Bahahahaha Dennis,

going to email this to some people in suspension for a laugh.. i like this bit, "Springs on there own do SFA no matter who makes them"

! remembers why he dropped this site..!

(hey keep going with your kings and firm Koni's Dennis is the expert)

it will reduce the squat make no mistake, but then you will need your shock set firm all the time taking away your adaptability, i mean what is the point in adjustable shocks if you cant adjust them to there full extent soft or hard?.

and so your aware its not bias, King "race" coils are fantastic i run them on my track car,

Bye SAU

Marc, do you know anything about Koni reds, or Koni anything for that matter? For a start they are fully adjustable, but internally only and have to be preset before assembly and then cannot be changed without dismantling the entire unit. Also, "do you know how many turns the valve has from off to stop"??? I bet you don't so your comments about taking away adaptability have no basis.

As you're in Melbourne, and therefore it's a local call, ring Toperformance and have a chat to them about Koni's before shooting your mouth off on open forum, because if Steve calls them, they will tell him same as I have said here, so when your emailing my quotes around the town, make sure it's in the right context and include everything in that paragraph, instead of picking it to bits making it something it is not.

Do you understand anything to do with physics??? Springs once activated build up inertia and without a dampener or controller will continue to bounce uncontrolably for ever.

Do you know why I came back onto SAU, well do you ????????????????????????????

I was asked to, I was receiving 5+ emails a week about diferent things to do with R30 Skylines, I bet you don't get the same eh?

Don't let the door slap you on the ass as you go!

[FJ20DR30]

Seriously Dennis?

i dont even remember disagreeing with you? i just feel that a sring rate increase will help.

sorry for this 200b its in no help to you..

your shocks (those Koni's) there perfect! and a firm up will help for sure,but ill stick to what i said a spring rate upgrade i believe would prove a benifit in this case.

i run 7kgs in the rear of mine with Koni's as well but they dont get close to bump stops even at full soft very little squat just enough to get good grip

i was hasty this morning as it really made me upset that someone cant share there opinion on here with out being chastised and in such a personal way.

anyway peace

[steve200b]

lets save the hate for the the ford/holden fans and just get along

Thanks for the info I have some direction to go now with the rear setup before i put more power in it.

Enjoy
