I was having a play yesterday when the rear end started fishtailing on a 4th gear pull at full boost from around 70mph ish. I was accelerating out of a very slight bend when it happened so the haldex may have been engaged. It probably wasn’t a massive amount of movement but felt very unstable. I’ve also occasionally had the back end step out a little in lower gears on full boost when traction is lost and the haldex kicks in but never fishtailed like this. I was hoping someone may be able to advise what the most likely cause might be so I know where to start looking to fix the problem.
Rear suspension setup:
Koni STR.t struts & H&R springs
Standard ARB with polybushed mounts
New ARB links
Traililg arm front polybushed
Silver project lower control arms
(Probably a bit too much neg camber)
Wheels/tyres:
8.75” et10 (inc spacer)
225/40/18 Goodyear eagle F1 (with slight stretch) 33psi rear (& 35psi front)
I suspected it’s probably caused by the slight stretch in the tyres but just looking for other opinions in case it could be something completely different
A few pics for reference
Thanks,
Steve
