Front Suspension Upgrades

[FlashGuy]

Been driving my G37S coupe with upgraded suspension for about 1 year now, and I think the stiffer suspension is taking it's toll on my stock suspension components. My current predicament is a growing dead spot (~ +/- 2 degrees) in the centerline steering and more pronounced rattles at low speed sharp bumps. I'm suspecting that the front lower control arm and front lower impact bushings are shot, thus contributing to the rattle and play in the steering.

Upgrades: Tein Mono Sport, SPL UCA, SPL rear camber arms, SPL lockout kit for camber, SPC toe bolt kit, SPL F&R endlinks, Whiteline diff bushings, and F&R Hotchkis ARB.

Usage: I track the car and take long road trips to the mountains every year.

I just wanted to reach out to the community for some thoughts on the next path to take.

1. Replace the current front lower control arm bushings with SPL spherical bushings.

2. Buy new control arms and install the SPL bushings. The reason being is there 80k miles on the car now and hedging a possible non-serviceable ball joint failure. Don't know if there are alternatives out there. I would like to move away from the OEM arm design to something more serviceable.

3. Replace the rear shock bushing with the SPL bushing first and address the rest in the knuckle at a later time.
