I plan on installing some swift springs on my '15 fsport but at 72k miles I figure I should swap out the struts at the same time. Any suggestions, other than OEM from lexuspartsnow, for struts?

 

Do you wish to retain AVS?

 

Yes, I would like to keep the AVS

 

Why not just get RSR or Tein AVS compatible coilovers? I don't know how much OEM strut costs but with all 4 corners plus cost of Swift springs, you may be looking at more than what coilovers costs. IMO, OEM struts are not matched for spring rate of lowering springs. You'll wear out the struts in time anyways. You don't have to lower your car with coilvers, but the added adjustments are nice to have. Plus the springs and struts are designed to work well together. RSR coilovers aren't cheap, you're looking at $2100, Tein is little bit cheaper but I have no experience with them. I love my RSR coiolvers, no complaints here.

 

Great info here! Just looked up the Tein system. It appears you can adjust ride height without affecting shock stroke. At $1750, it doesn't seem like a bad deal at all.

 

CKS also makes high quality coilovers for our GS that you can customized with Swift springs. I don't think they're compatible with AVS if you're OK with losing that function. GS-F guys loves their CKS coilovers. I'd have gone this route if I didn't already have RSR.

 

Been doing a bit of research and, if you want to retain AVS and have AWD, your only aftermarket choice is RSR. The Teins looks good too, but they only have fitments for RWD. If you look at the price of the OEM struts and the labor of taking them apart to change the strut cartridges, I would just do the RSR coilovers.

 

Rsr coilovers with avs are available now for awd?!

 

i think kyb extage works for avs too thats what im planning to get for my replacement

FWIW I contacted FEAL Fuspension, very highly rated pro race coilovers, and they said they can do a setup for our 4GS cars for about the same price as the RSRs. I may go that route in the near future but the RSRs are pretty tempting too.

One thing I wonder about is the perceived difference between luxury trim and F Sport. The F Sport is reported to be a little more aggressive. I wonder if any of that is attributable to struts or is it 100% software.

 

I believe the struts are 32 position so I'd say it's software. Pretty sure slgenuine struts are AVS or not, the rest is up to software.

 

This is the only way I would lower my AWD GS. Putting springs on the OEM shocks will lead to premature failure of the OEM cartridge. Been through it 2 times before with both of my Infinitis.
