nsta Posted September 8, 2006 Share Posted September 8, 2006 Hey guys, as title suggests, i get major headaches while driving along even 20km to the city now.....which i had none of before when i was on stock shocks/springs setup???? Im really annoyed as i paid top dollar, i have soften the damper up which has proved to easen the pain, but even i 10min quick ride will give me an ache now from the bumpiness!, should i possible harden the damper maybe??? i may have to give em back and get something else?

nsta Posted September 9, 2006 Author Share Posted September 9, 2006 BC Coilovers, and even the small bumps on the road tend to make my car bounce, and being in nz, the roads arent the best down here....so its kind of amplified....i have the coilovers soft all round right now, even a 5min drive makes me a lil sick!

What spring rates are you running?? maybe ring the company up and ask to exchange them for some softer springs etc. Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2476566 Share on other sites More sharing options...

Sydneykid Posted September 11, 2006 Share Posted September 11, 2006 http://www.bcec.com.tw/products/nissan.htmlthose are the specs incspring rate for r33 Front 180.62.012, that means 180 mm free height, 62 mm ID and 12 kg/mm spring rate Rear 200.62.008 , that means 200 mm free height, 62 mm ID and 8 kg/mm spring The standard front and rear spring rates are around 3kg/mm, so you have increased the spring rates to 400% on the front and 267% on the rear. That’s simply ridiculous. As a comparison the Whiteline/Bilstein Group Buy spring rates are a 20-25% increase. I strongly suggest that you return the kit, demand your money back and tell the supplier it is totally unsuitable for Australian conditions. cheers Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2480332 Share on other sites More sharing options...
nsta Posted September 11, 2006 Author Share Posted September 11, 2006 is that pretty much the same across the board (like teins, hks, spexi etc....) why are jap spec coilovers so tight Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2480629 Share on other sites More sharing options...
n15m0 Posted September 11, 2006 Share Posted September 11, 2006 bacause japan has better roads And generally coilovers are meant for track use, ie better road conditions as well. I've got Tein Superstreets and they are 5K fronts and 4K rears...which are firmer than stock but won't give you the headaches you're experiencing now Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2480651 Share on other sites More sharing options...
Sydneykid Posted September 11, 2006 Share Posted September 11, 2006 is that pretty much the same across the board (like teins, hks, spexi etc....) why are jap spec coilovers so tight Not sure, probably a combination of; 1. Their roads are a little better than ours, but not 300% better. Maybe if you drove up and down the Wangan all day, but otherwise no. 2. The shocks are fairly simplistic in their valving, so they have to use big springs rates to control the chassis. Whereas the Europeans tend to use lower spring rates with sophisticated shock valving to control the chassis. Which is technically a superior solution. 3. They try to do everything with spring rates, rather than use stabiliser bars, anti dive and anti squat geometry. As a comparison, in Australia we have a long history of stabiliser bar upgrades courtesy of KMac and Selbys. 4. Their aftermarket buyer relates hard/harsh/super low with good handling, which is, of course, totally false. 5. There seems to be a value for money equation that says you have to really feel how hard it is, so you know your getting something for your money. That’s reverse logic to, it feels so nice and controlled, the ride comfort is good, so it can’t really handle that well. Which again is totally false. Personally I reckon it is little bit of 1, 4 and 5 and a lot of 2 and 3.

r33_racer Posted September 11, 2006 Share Posted September 11, 2006 I wouldnt go so far to say that our tracks are in better condition then our roads....Its true coilovers suit the track rather then road, but thats more for height/ corner weight adjustment not so you can run super stiff springs because thats what you get in a jap spec coilovers.

n15m0 Posted September 11, 2006 Share Posted September 11, 2006 just get them to replace it with lower spring rates if thats an option at all. At those spring rates u have currently, ur car won't last long U'll start to get rattles in the cabin, bodykits start cracking, even the filament in the headlight globes will start to shatter...

nsta Posted September 11, 2006 Author Share Posted September 11, 2006 Thanks alot people for your help. Need to understand a few things....... Now i have coilovers, what options do i have......i hear that you can change the springs(which in effect changes spring rate????), if so what springs should i be going for, and does this have to be a factory option, or can i put say the stock springs, or whiteline springs fitted. How can i interchange springs within coilovers, or how does the workshop do it???, and is it a straightforward process to do? Will i still have height adjustment after changing springs, and will this affect damper settings(or is that all part of the shocks)??? sorry if i sound newbish but i am lol cheers Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2481435 Share on other sites More sharing options...
someonestolecc Posted September 11, 2006 Share Posted September 11, 2006 What they're saying is if you can ask the person who sold it to you to take them out and actually pull the coilovers apart and put in a different set of springs into them.

nsta Posted September 11, 2006 Author Share Posted September 11, 2006 Hey sydneykid, will the whiteline springs you haveas part of your package work in my situation?my 12kg r/8kg f, is much more extreme then even the hks/tein suspension which is generally 8r/6f..... it all makes alot of sense now, but imdefinitely going to have to change the springs.....whats invloved in doing this, do the springs have to be sized to fit the coilover shock???

Sydneykid Posted September 12, 2006 Share Posted September 12, 2006 (edited) Hey sydneykid, will the whiteline springs you haveas part of your package work in my situation?my 12kg r/8kg f, is much more extreme then even the hks/tein suspension which is generally 8r/6f.....it all makes alot of sense now, but imdefinitely going to have to change the springs.....whats invloved in doing this, do the springs have to be sized to fit the coilover shock??? I have helped a few guys out with this problem. As you have mentioned, the cheapest solution is to swap the rear springs to the front and then buy some more appropriately rated rear springs. For that option I would need to know the coil ID and its free height. Then I can specify a replacement spring that will fit the coil over shock. That works about 50% of the time and the guys have been happy with the result. Some guys still find the front spring rate too harsh. So we then change the front spring rate for one that is more appropriately rated. That satisfies about 25% more of the guys. The last 25% still don’t find the ride acceptable as the shocks are too harsh, even on their “softest” setting. So they keep the springs I have supplied, sell the coil over kit to someone who doesn’t mind the harsh ride. Then I supply a set of Bilsteins with (coil over conversions) valved to suite. So there is no waste of money in the process. PM me if you want me details. cheers Edited September 12, 2006 by Sydneykid Link to comment https://www.sau.com.au/forums/topic/133554-headaches-after-new-suspension/#findComment-2485572 Share on other sites More sharing options...
