Question Tire Thread and Suspension - SF Bay Area Local

Hi Guys,

Very recently I got a 06' IS350 and looks like the ONLY the left tire (driver side) in balding pretty bad on the inside curve and the outside curves. The car is completely stop - Luxury Package not Sports.

So, the mechanic who looked into this issue, asked me to get an alignment done and he highlighted that the car suspension might need some repair.

I am taking the car to get an alignment, but I wanted to check if there are any San Francisco Bay Area local shops who are specialized in IS's. Please feel free to throw in any recommendations.

I will post the alignment report to get all of your inputs. Also, if you all can give an estimate of how much I am looking at if I were to change the suspensions (Labor + Parts).

Thanks!

There won't be any Lexus IS specialty shops. Just look for a shop with a newer 4-wheel alignment system with good reviews; calling around will help quickly narrow down your search for this.

Post up your alignment results; you should have a BEFORE and AFTER specs sheet. Post both.

FYI, if you search on CL here about the factory front LCA bushing, you'll find many threads on the topic of how the weak factory rubber bushing during braking and cornering allows for the front alignment to possibly "eat" both the inner and outer portions of your tires. You might want to first purchase an aftermarket FIGs or RR Racing LCA housing/bushing, install it, AND THEN get an alignment.

Thank you, Gville350!

So, I got the alignment report and the mechanic at the shop is saying exactly what you have mentioned in your post.

He is recommending to put the following parts. Approximate cost is around $1400 labor and parts. Is that realistic? :O

Front:
Specialty Product 67530

Rear Camber Kit:
Specialty Products 84110

Attached is the alignment report.
I would appreciate if you all of you can suggest the best route of action I can take to solve this issue.

The recommended parts above are front and rear camber adjustments. Not sure how they would affect the toe issues. Go with the RR Racing USRS setup and it'll immediately help with limiting "tire eating". I'd forego with the camber arms in the rear and the adjustable ball joints up front and just go with the aftermarket front LCA bushing/housing.

Any idea how much it might cost parts and the labor to change to the RR Racing USRS setup?

I would say about an hour of labor. I got my on in under an hour in my garage with a floor jack and breaker bar. Very easy to do.

So, I just order the RR Racing USRS and the SPC Ball Joints 67530 and the SPC Rear Camper 67520.

Anybody in the SF Bay Area who can suggest me a mechanic to put these on or any one kind enough to help a new member? :P

Thanks guys!

So, I went to a different mechanic for alignment and putting the USRS LCA bushing. This guy is saying that it's my tire which is bad no need to change the Front ball joint and the rear camber arm kit.

My current tires are Michilin Pilot Sport A/S Plus 225/40 ZR18 92Y in front.

I have two questions to you all.

Is it possible that for one side of the tire is balding more than the other? In my case its the driver's side inside part.
Anybody using the above mentioned tires?

I've heard mixed results with those tires. Should have saved the money on those ball joints and rear arms. Still would recommend installing those LCA bushings to curb any future front inner tire wear.

Yea, man! I am returning the ball joints and the rear camber kit. I am going ahead with the LCA Bushing and a new pair of POTENZA RE970AS POLE POSITION for the front..

Struggle of buying a used car from the private seller!!

Love it man! Thank you so much for making me get those LCA Bushings. I really appreciate you suggested me to get them..

I got new pair of front tires - Bridgestone 970AS and the RR Racing Bushings and got it aligned. That's the report.

First Impression: Just like the other members have mentioned, the car handles like a 3 series - LOVE IT! The steering is phenomenal and the brakes are really responsive even though I have the Akeebono pads on. Akeebono are softer than the OEM pads.

Road noise I would say 8 out of 10, 10 being the highest. Keep in mind as far as I read the reviews my tires are suppose to be noise as well.

Overall, the car doesn't feel like a old man's Lexus for sure! If anyone wants their IS to be a couch don't get the bushings.

Next steps after few months, need the replace the shocks as one of them is bleeding - going stock for that.
