I finally received my bushings today. Will install maybe this weekend. I've always had these on most cars I've owned, and it was a great improvement for steering feed back. Thanks to "Yodog" on this forum. Otherwise I would of just never thought they had them available now. Daizen is the brand they've done many things for the early year model Lexus scene. You can get them from TM Engineering.com
I just finished installing these on a AWD IS250. It's a PITA, but it's doable! Without dropping the subframe. Initial reaction the wheels turn as soon as you move the steering wheel. Also it's a lot firmer. Before there was a delayed mushy feeling. I haven't drove the car yet this is just moving back and forth in my driveway. Backing off the ramps, and parking the car feels tighter for sure. See pics below of the OEM bushings passenger side is slotted for movement. The new bushings eliminate most of the horizontal movement.
That is awesome! My car is 6 hours away from me getting those installed along with about 30 other misc. mods and parts at Sonic Motorsports I hope that slop gets eliminated and I can finally take advantage of my upgraded 2012 IS-F Steering ECU!
Last night I took the car for a 70 mile round trip for the heck of it on the freeway. The front end feels so planted. I have the 08-10 ISF SECU, and RR USRS. The car on the long smooth stretch is so smooth even more than before. As for NVH it picked up about maybe 10%. The slop is completely gone that's a good thing. I used to hate how the steering was all over the place on uneven roads. It always felt like the front 2 tires were on a pogo stick. At low speed turns feel heavy like your loosing steering assist. I'm sure eventually I'll get used to it. It will almost feel like it's not even there. Well with all the suspension parts your adding to your car. I'm sure you'll enjoy the handling. Give us some feed back on how the car feels after wards.
Thanks as well for providing the torque specs. You saved me some time from searching the forums as my bushings are currently on the way.
Yeah I had to dig around on the forums. I was bolting everything down when I realized what torque specs. Thank God for mobile internet, and CL forum's someone has already asked those questions.
Slightly on/off topic but....
When wrenching and you don't know the torque, a simple tip is this, (which I used myself the other day), when BOLTS/NUTS stop turning the fasteners is now in the elastic mode where material is stretching.
In short, fasteners only stretch so much before something breaks so pay attention to when motion stops as the fastener is very near it's yield strength.
My scenario was 350 front caliper bolts. Didn't have the info handy during assembly but guessed bolt was good for 65ft/lbs so I set the Snap-On wrench there. I saw the bolt STOP turning at 55ft/lbs. I stopped before it clicked and backed it off.
Looked up the real value as I thought the bolt was good for more but spec said 58ft/lbs.
Moral of the story is pay attention to when bolts/nuts stop turning. The stretch/elastomer period is usually a 1/2 turn or less before permanent damage occurs and the fastener is breaks.

What kind of tools did you use to press out the old bushings and press in the new ones?
