Need Help With Stiff Ride

Hi all,

I got myself a R33 S2 GTST recently. The ride height is perfect for me. What I don't like is the stiffness of the ride on Sydney Streets.

I had a quick look underneath. I am not sure if they are coilovers or not. How can I tell ? The brand is Apexi. They are blue in colour. Part numbers are below. I could not find them on the net ? Is their an Apexi Distributor/Dealer in Sydney

Rear Shocks

Apexi 237-N005-R

(GL23)

Rear Springs

M3X01874

Front Shocks

Apexi 237-N005-F

What kind of springs are they? The shocks have an adjustment setting at the bottom. I have put them to the softest setting. Haven't had a chance to take it out for a spin yet. Front's were already the softest setting.

I am not sure of the condition of the shocks. Car has 59xxx kms on it. If the setting does not help, can I just change the springs to a softer one, provided the shocks are in good order. How can I get them tested ? Do i have to remove the shocks/springs form the vehicle. If they are stuffed are these rebuidable.

I am trying to keep the cost to a minium.

thanks heaps

Hi all,

I have done some research and it seems I might have Apexi T-max Shocks with possibly factory springs. Does anymone know what the spring rates are for factory springs or have any experience with T-max shocks.

thanks

easyest way to get a softer ride is to get new springs put in with a softer rate. Someone like your local Pedders should be able to figure out what your after if you talk to them for a bit and show them the car.

new springs if there just the standard type in there shouldnt cost too much, id have a stab in saying about $400-500 fitted?

If there height adjustable coilovers, to change the springs in those (small type spring) id be guessing more around the $800-$1000 fitted for some custom King Springs or something?

if you could post a pic of the actual coilovers it'd better help people to give you the right advise?

unfortunatly most Jap aftermarket coilovers are fairly stiff, great for handling, but yeah...not so much for street cruising.

They are not really coilovers, just struts. but I am told they they have height adjustments. Just struts. I might have to visit the local pedders.

I'll get pics when I pull them out of the car.

thanks for your suggestions.

Anyone know what the springs rates are for the standard springs in a R33 Gtst

thanks

This thread shows you how to measure springs so that you can send the dimensions to me and I will work out the springs rates for you.

Armed with the spring rates you can then make an informed decision.

:laugh: cheers :P

Hi Guys,

I have removed the springs and given then dimension off to SydneyKid.

I also had them tested at K-mac in Rockdale. They told me the Fronts are 160 lb/" and rears are 120.

I am not sure how accurate this is, beacause they are the progressive type and I don't think they probably loaded them enough so I am very interested to see what SydneyKids calculations are.

Is there anyone else in Sydney that can test spring rates specifcally around Liverpool.

Does this mean, that my shocks are probably too hard. I have put them on softest setting. I have also adjusted height to raise it before I put them back on the car.

Anyone know where I can get them re-valved/serviced in Sydney. The only ones I could find were Shock Reco in Brisbane.

The other question, why is the recommnded Front height higher than rear. Mine are set at 337mm all around I have raised them to approx 345 mm.

Will that make any difference in ride quality or its purely a height/preload adjustment.

I would like to get SydneyKids suggested shocks but cannot afford them at this time.

Will my springs be able to work with the his recommended shocks.

thanks again.

If those spring rates are right, the front will definitely work well with the Bilsteins (the Whiteline springs used are 165lb/in) but I'm not sure about the rears, they seem about right though, you will have to get SK to answer the question properly.

There is a difference in heights front to rear as the guards are cut differently, more clearance at the front. It should be a bit more comfortable raised up a bit and less bump steer. Shouldn't be a huge difference though.

Hi Guys,

Are KYB shocks any good with the springs that I have, which are probably lowered and not a very high spring rate.

I might be able to get a good deal on them..

Are they better than stock shocks in temps of bump valving and rebound for slightly higher rated springs.

thanks

Hi Guys,

I was after an opinion on the state of my suspension. I took some photos. The first two are of one of the front shocks and the 3rd is a rear unit.

I noticed that the front boots of both front shocks are stuffed while the rear is intact. Is this cause there is a lot of movement in the front, due to the weight.

I was wondering if the front bump stops are too long. Could this be a cause of the harsh ride. The center to guard height is 337 mm all around.

I was also reading up that these are short stroke shocks. Anyone know the dimensions, travel length of the blisten and/or kyb shocks. Trying to work out what the height might be with kybs and my current springs.

Also, can anyone tell me what the free length is of the front/rear Whiteline springs

Anyone used the shockreco place in brissy. Am contemplating on whether I should get my current shocks re-valved.

thanks for you help.

      Mistakes were made, my R34 Story

      By GTSBoy · Posted

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
