Hi guys, I really like GKTECH as a company bought heaps of quality stuff from them. But unfortunately they only sell rose-jointed arms, I understand in a race car you 100% don't want the flex from a bush. However my R33 really only sees street driving, with the rare venture to the track. 

I would like to buy a complete rear suspension arm kit which is adjustable (my car is lowered) but which has bushes. 

Now, am I right in saying that rose-joints and solid bushes etc in the rear end promote cracking/abnormal wear of the chassis due to it being fatigued? 

Should I just go ahead and purchase the gktech arm kit and will it still drive nicely on the street without too much harshness? 

Cheers.

Hardrace do a rubber bushed adjustable arm kit.
I have ran the rose jointed arms for years and didn't really notice the noise difference until I went in my mates car that has rubber bushes, much smoother and quieter (more enjoyable daily) .
If just a street car that goes to the track once a year the rubber bushed would be the go .

There is really no point buying new arms if you want to use bushes instead of rose joints, that's why there are very few available.

You just put adjustable bushes into you factory arms (both ends if necessary) and you will have plenty of adjustment unless you are running poor geometry anyway (eg, way too low). Whiteline and other brands make adjustable bushes to suit.

driftworks sell the fully adjustable kits with the choice of rose joints or polybushed ends.

dont know if it works out cheaper ordering direct from them or through an australian supplier though

    • Pretty much what you'd expect at that power level. Hypergear turbo, long list of supporting mods, full Haltech catalogue, etc.  I'd say this goes for most drivers, suspension is still a dark art for most people. And it's really hard to convince someone how much better their setup could be...  
    • They are what I will be installing. 640s for me.
    • Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.
    • What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
