I run half bush half rose joint in the rear of my car as class rules stipulate no rear firewall mods can be done (no equal length)

Maybe on circuits and on cars with IRS complete rose jointing is the best option

but with an unequal 4 link, the binding in the top left with all rose joints is terrible, a lot of mid corner speed can be picked up with bush end (at least of hillclimb/tarmac rally stuff) where the road surface is constantly changing and the suspension is higher and has more articulation than a dedicated circuit car
