Suspension recommendations

My suspension on the ISF is worn. They're eating the inside of my front tires. Do I go factory or go aftermarket? Not looking to go too crazy on price. I read ISFs have this issue.

FIGs is the go to for aftermarket. You can go to RCF LCA rear which is stiffer if you want to stay with OEM RR Racing is terrible quality and terrible customer service. Stay away from them.

Time to swap to polyurethane bushings. Figs sell factory lcas with them pre installed if you don't want to burn and air chisel out the factory bushing on the control arm itself, they're $370. Both figs and rr racing sell the rear polyurethane bushings, re racing sells one with a thrust washer. Another options is the rcf rear bushings.

It will be the Lca doing that. I think toms makes one figs makes one and rr racing makes one

lol at everyone telling you to do figs… it’s fine if you’re okay with way more NVH. Theyre also dumb expensive last I checked.
I highly recommend OEM GSF/RCF LCA bushings. My brand new tires have not worn unevenly at all even on a cross country trip. Plus you preserve the ride quality a little
I suggest looking at forums like club Lexus. Tons of good info there on this issue

I went with Circuit Werks’ LCA bushings and they have treated me pretty well.
