Hi all,

I brought a R33 this weekend and having to drive it home (1000km) it was so loose in the back end like a big bump in the road and it felt like a trampoline, the back end just about lifted of the ground. It seems really really soft and im a little confused why. Maybe im dump but yeah.

This is what i was told was in the car "Gas shockies (Gab suspension)" Can this be pumped up or what????

Im picking the the shockies are gone but looking at them they look nice and new still shinny paint on them

If anyone can help out, that would be great cheers

gas shocks don't need pumping up, they are supposed to be a sealed unit.

maybe they are simply set too stiff, so when you hit the bump rather than the shocks absorbing it they pushed the car up into the air, and then the back wheels came down hard.

even in totally stock form the back end feels quite lively, so with stiffer shocks i'm sure it would be a problem!

My pulsar and skyline do the same thing.

I noticed with aftermarket suspension, the rear will bump and kick a bit on rough roads.

I was informed that making it a little stiffer in the rear would get rid of this because the rear was under shocked. Dont know how true this is or how well it works. Have only just set the rears stiffer so will have to wait and see.

What happens when you "bounce" the rear end of the car? How far can you push the back down when you lean on it? What happens when you release the load?

If you get it bouncing, it should stop within 2 bounces - otherwise the shocks are shot.

If you have no joy with the responses that you have heard, i have noticed with cars that are "lighter in the back end" than normal cars, to run a slightly lower tyre pressure in the rear wheels, see if this helps, i would recomend about 32 - 34 in th rear and about 36 in the front. see if that helps with the bouncy effect.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
