Perhaps if I was going to run 6kg springs and rose jointed rear end, yes it would be too solid. However, I am trialing a variety of spring rates that are softer than commonly used in the 86 community to find just what is going to offer the best performance for what i want to do. The idea of equal length arms and them being rose jointed is so that the diff has no resistance to moving up/down, rocking left/right. Same as not having any sway bar, I want my car to roll around over the diff, thus keeping power on the ground and obsorbing somewhat the lateral forces transfered when altering direction at speed away from wanting to force the car into a slide.
Was going to. Decided against it. Meh, V8 Supercars run live axle rear end still, must be alright to some extent im figuring!
but you keep zero camber all the time which must be a plus with a billion hp
so the answer isnt in some wide grippy tyres?
ive driven with cutties, 8 & 6kg and 6 & 4.5kg.. for good all round street driving im quite happy with the 6 & 4.5kg. up until recently i was running 10ish and 4.5, looks gangsta as could have the guard sitting on the tyre (very very little compression) and may have been usable with some stiff shocks. going back to 6kg in the front feels really soft but it turns much better now. i had just adapted to the way it handled with the 10's but going back to 6's kinda realised how much understeer it had, esp mid corner. will slide with 205's on the back haha!
oh and 8 and 6 with kyb shocks and rear swaybar would power drift with a 4ac at like 40kays. so good for low powered skids but felt very unstable around highspeed corners and little to no grip. but the slides where quite controllable.
thats just what ive found, i think id like to try maybe 6.5 and 5kg

Nooooo...... Stock sprinter (lowered) rear end SUCKS for squat, simply because of the geometry. A quick explaination of attaining squat is that it is all to do with the angle of the upper arms and the length of them compared to the lower arms. For more squat under power, the upper arms need to be inclined (at the front), opposite for squat under brakes. Its a comprimise that can only be found through trial and error, to suit the driver's preferences and driving style.
And yes, some nice wide tyres will also be helping.....
your using 16x8's from memory? well 225/40 semi slicks should give heaps of traction i would have though?
also v8 super cars are fairly low tech really. big chev motor up front, gear stick in the middle and a old lock diff at the back... they do wheel alignments with string. for Australias biggest race series kinda a bit ghetto and back water style. look at JGTC those are closer to F1 cars then our V8's.
dont they run a single panhard too not a watts linkage?
yes quite often do it actually as most wheel alignment machines wont work on cars with maasive neg camber
jgtc cars are a lot more developed than v8 supercars lest not forget that v8 supercars banned gtr's and what not because they couldnt beat them and im sure it would still be the case today
