Here's a thread for your battery question: https://www.clublexus.com/forums/is-...d-threads.html

It seems like it was a select few. I've had a '14 since November of '13 and never had a single issue with the battery drain. I just replaced my original battery in February because I could tell it was starting to get sluggish on some starts.

 

Hey guys,

I have brake pad question.

I have a 2014 IS350 AWD F Sport. It is CDM if it matters.

I know the AWD 350s have different front rotors than their RWD counterparts. But are the pads different too?

From what I am reading, Lexus offers two different front brake pads, more aggressive bite higher dust pad and a lower dust pad that is blue.

I am sitting on a set of OEM blues to install. I got it from a dealer and provided them with a VIN. Did I get the right pad?

I am.wondering if AWD IS350 F Sports get the regular low friction blue pads and like the base model and only RWD F sport models get the high friction pads.

 

Also... how much does a sunroof weigh?

2014 IS350 AWD is a stripped down model aside from the F Sport package. No sunroof, no navigation or anything else .

 

The pads are the same fitment. F Sport got the dusty pads, the non F sport got the other ones. From a fitment perspective, they both physically with fit the 200t, 300, and 350 front calipers.

 

Hard to say for your specific car, but I know in the past on a BMW 3 series, people have weighed the whole assembly at about 40 lbs. So possibly around there.

Don't forget when you lose the sunroof you also typically gain a reinforcing rib where the sunroof went and some steel panel around where the sunroof would sit. So you probably wouldn't get the full 40 lbs. I'm guessing your car is still around 3800 lbs being AWD still.

curious what a 3is headliner looks with no sunroof. can you take a pic. did you get it on purpose without sunroof?

 

I'll grab a pic tomorrow. It's black. And when it rains, there is so much pitter patter.

My 2014 IS350 AWD came with the F Sport Series 1 package. Just the F Sport specific upgrades. No backup camera either. Being CDM, it does come with a heated windsheild and headlight squiters though.

Premium package was a lot less money but those cars here came with the mesh 18s staggered, back up camera and a sunroof.

I got my car off lease. My cousin was the original leasee so I had no choice....

 

Another question.

My car has been lowered since I got it for about 25k kms. It is pretty low, but not dumped. Maybe RSR SD low or lower. It has 83k kms on it now.

Should I have any problems with axles in the near future? Can anyone who had a 2IS chime in? Ripped boots, balljoints, axle cups? New rear endlinks are already on the list.

 

Is there anyway I can see these dampers without removing the front bumper? What's the lifespan of these dampers?

 

To the person who asked about lowering problems... you might have issues with the bushings because most installers don't loosen and re-torque bushings at static ride height. you'd need 1) The knowledge 2) the care 3) ramps or an alignment rack so the car can be at rest.

When I lowered my car i made sure to loosen and retorque the control arm inner bolts as to remove preload on the bushings. A arms too. lexus instructs to do this when lowering as well.

As far as damper... my understanding from looking at parts on ebay is that the damper is under the engine area. not behind the bumper.

 

I did provide specific values several times in previous posts. But its specific to my vehicle, my driving style, and the load I carry. That said it may work for many!

Putting our opinions/experience aside (hard to do given that fact that I've aligned thousands of vehicles; cars, trucks, performance vehicles, motorhomes, trailers, ATVs, race cars, etc)....

Allow others to inquire about the best alignment for their needs and vehicle usage. Zero toe may sound ideal but is NOT ideal for all vehicles.

Bottom line is the user needs to pay attention to wear on new and used tires. Very small changes in pressure and toe can yield more miles from tires. This may require adjustments to pressure and toe along the way.

 

You can always pull a pad to find out. Or do you get a lot of brake dust? If so it's probably high friction. If not a lot, and a more brownish dust, then probably low friction. I think cars equipped with summer tires got high friction and those with all seasons got low friction (would make sense).

Also if you have more than 15,000 miles on your current pads, they're probably not the high friction ones since they tend not to last that long =)

 

I believe the F Sport trim includes the high-friction pads regardless of drivetrain or tires. I know I have those pads on mine - I've had all the associated quirks, too, such as squeaking in cold weather and tons of brake dust.

 

Yeah even for canadian models? I can't imagine coupling high friction pad with grandma tires. i remember my dealer telling me that some ISs got the all seasons and some got summer. Hard to tell since at least you can look at the tires. OP, what color is the brake pads in the back? that could be a clue since you can see them clearly.

 

Yeah, I am having a hard time finding that information for Canada. I know in the US at least, all IS F Sport models come stock with the high-friction pads, or so I have been led to believe. My 2016 IS 300 AWD F Sport does, anyway... and it has the all-seasons.
