Hi Guys,

I dont really know a lot about suspension but here it goes...

my rear right suspension is stuffed. I took it to a suspension place and he said something about the oil leaking...or breaking.

Every time i go over a ditch or small or large bump my back left suspension hits my chassis ( i think). A loud noise coming from that area (although does sound like my boot hiting). Im pretty sure its my suspension as he put his hand where the suspension is and his hand was pretty much covered in oil.

Im not too sure what he was on about and my reaction was where to fix and how much.

Just wondering if anyone has has this problem b4? how did u fix and approx how much. ohh and if ur in melb where did u get it done? In particular to Tien Coil over suspension.

Thanks heaps.

I had one that used to thump like what you have explained.

I pulled the strut out of the car and there was a little bit of play in the top hat. It ended up being the top nut was loose about 1 turn !!!

I gave it a tighten with a spanner (about 2 turns) and then it was totally silent.

Unless you've got oil leaking all over the place which is an internal thing, then it could just be something as simple as the top bolt.

The seals in the sus are gone. So the shock is working on the spring mostly so it probably tops and bottoms out a bit. There are quite a few places u can get it fixed. You could try suspension city in north melbourne.

For Japanese suspension, I believe a lot of the time to get them reconditioned is just not worth it as its pretty expensive and most places will fall over if they see a TIEN, Cusco, HKS, or Zeal suspension and just say "its stuffed, buy our XXX aussie brand"... not knowing those setups in Japan would set you back $4-5k. But you can try what Nismo32 suggested.

Try putting weight on the corner in question and pushing down and letting go quickly.. does it bounce up and down a few times?? Should only bounce once if they're still in decent condition. If it bounces visibly a few times your strut is on its way out.

Apparently the upper pillow mounts can also go before the rest on coilovers.. I'm not sure exactly what they do, but i believe they are like rubber bushes that keep everything all secure and in place where the strut meets the strut tower. That could explain the thumping as well.

Pred: Tein suspension are damn hard, even when they are stuffed, i will give you a demo in my car next time i see ya.

Champinco: When my suspension blew a seal and had a worn shaft (just like yours probably has) my mechanic took them to a place called "Cruise Tune" in Dandenong. I didn't pay for the repair as they were only 2 weeks old from JMS. JMS are the people that recommended them, apparently they send all their suspension repairs there, even though JMS are based in Sydney.

They done a great job. You should get both your front suspension done to match them up. Be warned though, as they can sometimes be hard to get in contact with, as they do alot of track testing for race cars.

thanks guys....greatly appreciated with all ur input.

thanks pred...makes a little more sense now.

nismo32...i went to the place u told me to go to (north melbourne) off abbostford street) suspension city and the guy (i think damian) told me he cant do it and he gave me a contact in moorabin. the only problem is...its too f!@#en far. i live in the west. are there any other decent places around the city or west or north? or is every supsension place too scared to touch skylines!!!

Cheers

An AL... depends what type you have ad to how hard/not hard it is.

Like i've said before.

GT Suspension - Mt Alexander Rd Flemington.

The wont shudder at the work Tien or anything.

when mine custom set was repaired they had a box of brand new tiens sitting there for a car.

So they DO know what they are.

Yes, that's correct :uh-huh: .

They sometimes send their 2nd hand suspension down here to get repaired by these guys, as they cater for racing cars and know their shite. :(

I have only known Tein suspension to be hard, even on the softest setting. As their coil-overs are mainly designed for racing and drift. Also Japan's roads are so much more smoother than ours, so stiffer suspension is barable.

Please, correct me if i am wrong.

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.

      It still combines inches with mm, especially when you have .5 inches involved, and mm and inches that can go in either direction. This would give a clear idea on both sides of the rim, right away, with no arithmetic. Even better if somebody gives you the dimensions of the arch of multiple cars. i.e GTR may be 125mm, a A80 Supra may be 117mm, or something along those lines. Yes, you can 'know' that going from a 10in rim to a 10.5in rim with the same offset moves both sides about 6mm, but you still have to 'know' that and do the math. Often it's combined. People are going from 9.5 +27 to 10.5 +15. You may do the math to know it, but if it was going from (I had to go look it up to be sure) 241mm/2 - 27 - 93.5mm from the center line to (more math) 266/2 - 15 (118mm) from the center line. Versus 93mm vs 118mm. It's right there. If you know you have a GTT with 100mm guards you can see right away that one is close to flush and the other absolutely won't work. And when someone says "Oh the GTR is 120mm" suddenly you see that the 10.5 +15 is about perfect. (or you go and buy rims with approximately 118mm outward guard space) I think it's safe to say that given one of the most common questions in all modified cars is "How do offsets work" and "How do I know if wheels will fit on my car" that this would be much simpler... Of course, nothing will really change and nobody is going to remanufacture wheels and ditch inches and offset based on this conversation :p We'll all go "18x9+30 will line up pretty close to the guards for a R34 GTT (84mm)" but 'pretty close' is still not really defined (it is now!) and if you really care you still have go measure. Yes it depends on camber and height and dynamic movement, but so do all wheels no matter what you measure it for.

      But offsets are simple numbers. 8" wheel? Call it 200mm, near enough. +35 offset? OK, so that means the hub face is that far out from the wheel centreline. Which is 2s of mental arithmetic to get to 65mm to outer edge and 135mm to inner. It's hardly any more effort for any other wheel width or offset. As I said, I just close my eyes and can see a picture of the wheel when given the width and offset. That wouldn't help me trust that a marginal fitment would actually go in and clear everything, any more than the supposedly simple numbers you're talking about. I dunno. Maybe I just automatically do numbers.

      Sure! But you at least have simple numbers instead of 8.5 inches +/mm, relative to your current rims you do maths with as well, and/or compare with OEM diameter, which you also need to know/research/confirm..
