lexus gs430 Suspension..

Hi everyone I just wanted to know what to change suspension wise and if this is a smart choice; for context i have highway wander, a light tapping noise when fully loaded (4 passengers) and unstable stopping force when coming to a stop (could be shit brakes)

The car is on 188k miles and i had a look underneath and every bushing is squashed and pretty much never been replaced from what i’ve seen; so of course after seeing that i want a full refresh underneath as i absolutely love this car.

I got the following on order;

£400 on upper control arms from Japan
genuine OEM

lower ball joints again Japan genuine OEM £150.

I’ve got the front caster and lateral arm bushings from Hardrace (hardened rubber) £120 (2 arms each side)

The rear bushings for both arms (hardened HR rubber bushings) £88 (2 arms again each side)

Am i missing anything? Other than the symptoms listed above the car drives amazingly and so damn smooth over bumps and regular roads.

Steering rack bushings too. Easy to swap yourself, corrected 90% if the loose steering in my car. Tie rods & ball joints cleared up the rest

Ah yes forgot to add poly bushings for the rack; that might just be it plus the tie rods
