R34 Gt-T Suspension Travel - How Much Is Standard?

How much travel in the + and - direction should an R34 GTT have? I just had a set of Bilsteins fitted using std springs and the rear felt weird.. very unsettled and "hoppy" and made some ugly mechanical clunks when going over bumps. It felt like I didn't have proper suspension travel.

I took it back to the shop and with standard springs and standard circlip groove there is *zero* suspension travel in the droop direction. ie, the mechanic jacked up both sides of the car and the suspension arms didn't move at all, the car simply lifted off the ground and the wheel went with it. No wonder it felt weird, I only had "bump" travel.. no rebound travel.

Mechanic suggested extra grooves and lowering approx 20mm. I'm fine with this as it ended up a bit higher than standard with new shocks and subframe bushes. However, I'm wondering if 20mm of spring platform change is going to give the suspension enough travel. What's the normal travel figure? It almost sounds like they've put the wrong shocks in.

Too short a shock. You need something longer with longer springs. Shorter with shorter. 2cm would be pushing it I think.

It's stupidly dangerous ATM, if you brake hard enough the rear may lift off the ground, I've seen it happen.

I'll try and find the video of an is200 that has no travel, he hit a small bump while booting it on a freeway and lost control. It wasn't pretty.

Edit: just saw you're an '03 member. I feel like I've been trolled.

That video is fail, but I knew it would be as soon as I saw those stupid f**king wheels poking out with ridiculous camber. Aside from no suspension travel he's practically riding on the sidewalls.

Thanks for the advice otherwise, I know what feels right and wrong and the back end was all kinds of wrong. It's back at the shop, and I'll call them in the morning to make sure they fix it properly. I'm mainly wondering what a sensible amount of droop is (how much the centre of wheel to guard changes when you jack up one corner, is the droop)

I think there may have been a rash of ridiculously short Bilsteins sold to Skyline drivers at some stage. I was going to buy a set of almost new Bilsteins that were coming off an R32 in favour of some (shitty, no doubt) coilovers. These things were more than 100mm shorter than my existing R32 dampers above the spring platform, and 10mm shorter below. These cannot have been intended for a Skyline, must have been for something else. You wouldn't have even been able to fit my springs onto them. Weird.

80mm for standard Stagea shocks/springs. Similar/the same as 33 & 34 units.

May give you something to think about tonight. But yours and coilovers will be shorter than this. I'd say 40mm may be adequate for a daily. But I'm not sure

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
