KE70 4 link Arm options
Hey guys
Am in the the midst of putting the diff back in my ke70, and noticed that the upper diff mounting points have suffered alot of distortion and stress.(broken a few spot welds and a small crack in one of the upper mounting brackets).
I have been running the T3 adjustible 4 link rods for about a year now and ive noticed the rear end of the car has a lot more creaks then it used to. From what i can see, when the car goes over an uneven surface (hill or drive way) the links move to a point then bind up and put all the pressure on the upper diff mounts.
What im wondering is, can i stop this from happening by adjusting the lenths of the 4 links correctly?(currently set to standard length)
Or is that just the characteristics of spherical 4 links?
Have been doing a bit of reading and frak and a few other members on here suggest that, using the standard links with urethane bushes rather then the spherical links.
This sint ideal for the diff pinion angle (points the nose of the diff down towards the road, from what ive read the nose should be 2-4 degress above level) but will put alot less stress on the mounts. But what im wondering is, will the standard links make the car axle tramp when drifting? (the car is a dedicated drift car)
Another option i was looking at was running standard bushed upper links and the spherical lower links so i still have the pinion angle adjustablity. But will this just the transfer the torsional stress to the lower mounting points?
The car is pretty low at the moment chassis rails about 80mm off the ground, but want to get the car lower so will need an arm set up that will work with a very low car. I know that the best solution is to go an equal 4 link set up with the car that low, but funds dont allow that at the moment so need an interum solution.
Let us know what you guys think.
Cheers
Ryan
