gu panhard bracket series 4 fouls on suspension

[outer limits]

Hi.

This might be a fairly isolated problem

I have a 03 gu patrol with a snake racing kit in it. being the 2 - 4 inch radius arms the diff looks to be moved forward. My issue is that on some of the gu's the panhard brackets actually run a spherical joint instead of a normal bush like the rear control arms. Being a bigger panhard bush means e bigger bracket of the chassis. I have just put new coils and old man emu shocks in the front of it. (old tough dogs were a rust prevention with that much oil comming out of them) I have extended the bump stops 30mm as arb say you have to. but my panhard bracket still hits the right radius arm.

all bushes in the car are brand new.

my question is. do i change back to standard radius arms to move the diff back or extend the bump stops even further on that side.

Has anyone had this issue with this before and i am at wits ends with the knock that comes out of it with the slightest dip in the road.
