top or bottom fitment? opinions on where is the best.
Personally I think of it like this; when you lower the car with the original tie bars, you get more -ve camber. (We all know that, which is why we're on this group buy.) This is because the OEM geometry of the rear suspension results in the top of the wheel moving through a tighter arc than the bottom as the suspension compresses. Hence the main issue is that the top of the wheel is permanently angled too far inwards when the car is lowered.
So, to correct that problem, the upper arm needs to be made slightly longer; and therefore I will be using the adjustable arms to replace the upper standard items.
If any of you are also into RC cars like myself, you will be familiar with this effect, which happens when you run a shorter rear turnbuckle vs a longer one. Shorter upper arm = more camber change under suspension load.
Apart from the fact that I'm right, of course...!
C'mon JoJo, just admit it.
Re. toe adjustment, are you saying that with them on the top you can't get the toe to the right angle?
I'm saying it's difficult to get parallel toe with the bars on top, because you have pushed the trailing arms out wards from the manufacturers specs, but if you stick them at the bottom, to pull the trailing arms inwards, then the toe adjustment is easier. That's if you choose to run parallel toe, I run factory toe for the sake of safety incidentally.
Regarding the top and bottom theory Paul, I believe the part numbers are the same for top and bottom factory arms, which means they are the same length. The camber happens because the mounting holes are closer together at the diff end of fitment. What you are saying is, the camber happens because the upper arm is shorter, so the natural geometry of how it's all bolted together mean by extending the upper arms, you get less of the camber effect with suspension compression. What I am saying is, if you stick them at the bottom, and shorten them to correct camber, the top ones will still be longer than the bottom ones, so in effect, the same thing happens when you stick them top or bottom, correct?
What it comes down to is toe adjustment, and whether you want the extra wide track that fitting them at the top gives? Fitting at the bottom is also easier on a set of axles stands outside your home.
Again, it's all personal preference. :icon_thumright:
Does this mean that pulling them in from the bottom keeps the track standard? Or is this narrower?
Hi Chris, they are going out in order they were paid, and that is a week behind at the moment, im hoping all that have paid will have them within 2 weeks..Hi Dave,
How's the stock looking for these?
I'll be making the remaining payment on the 28th for the 2 arms. Just wondered if you have them available to send out after the payment has been sent, or you are waiting for some more items/bushes to come in?
