Some More Parts to Improve the Car...

In my quest to improve my IS-F in the most efficient manner possible, I have been slowly collecting some parts over the past year or so which I thought would bring me the best bang for the buck. Because I haven't been as good at updating this blog as my GT-R blog, I'm going to simply lay out all of these parts.

First -  I decided to replace the OEM halogen fog lights with later year (2011-2014?) OEM LED fog lights - just plug and play...

Before

Much whiter!

And yes my car wasn't clean when I took this photo...

As for performance of LED vs halogen, hard to say really. They are mounted so low and act only to fill in the dark space under the headlights so I think the effect is more of a visual, than performance difference. Oh well, wasn't that expensive and it gives a more modern look...

I had also learned from Yamada-san at CREF (where I had the clear film installed) that when Toyota was developing the IS-F, they found that the large amount of power meant that the rear subframe would actually move and cause some instability, and that this was especially noticeable on a rain slick track. So, Spoon Sports developed the Rigid Collar kit for the ISF.

Just a few collars...

For anyone not familiar with the Rigid Collar concept, here is a video link that describes how they work.

Yes it sounds too good to be true, but yes they work and I will go into more detail in a future post about what they did for my car's handling. I had gotten them for my GT-R and was suitably impressed so the lack of internet feedback on their use on the IS-F didn't bother me.

I had also read on the ClubLexus forum how the Apex'i throttle controller made the car feel much more responsive (but not necessarily faster - but that's ok, I just want something more responsive!). So, I ordered one and the car-specific harness.

In a later post, I'll discuss this part - all I will say for now is, it really is worth getting!

Finally, some bling - I found something in my closet that I had ordered when I first ordered the car, but was not delivered in time for the dealer to install it, a dry carbon fiber rear license plate frame from LEMS.

Two photos from their website (as I was too lazy to unwrap it before handing it Ninomiya-san to install):

Here is the rear license plate before:

... and now afterwards! 

As you can see in Japan, there is this metal "cap" on the upper left bolt that has to be installed by special tooling (available only at the DMV). So Ninomiya-san had to make a quick trip in order to get it done... but I think the results are worth it!

Now I have to decide whether to splurge on a matching dry carbon fiber FRONT license plate frame and/or a rear trunk lip spoiler...but before that, one more piece of (possibly functional?) bling... stay tuned!

Sunny Day Means a Wash and Detail!

Right before Japan's raining season (late June and July), I happened to be home on a weekend where I had some free time. And it was nice and sunny.

I had recently noticed some minute scratching in the paint surface, so in addition to giving the car a wash, I decided some work with an orbital buffer would also be good.

Using, of course, my favorite car care products from Zaino.

I know, it's not good to dry in the sun. I had to move fast...

Loe how the water still beads even though I don't wax the car regularly. This is the Zaino AIO in action (plus the occasional Z-9 or Z-7 instant detailer spray)

Blinded by the light!!

Another shot - I wonder if I should get an OEM carbon fiber trunk lip spoiler? 

Here in Japan, with our narrow streets, I had to park and not block the main street!

All done! Hard to tell the gloss though...

Here we go. 

So what do you think? Shiny enough? I think the Lexus has very high quality paint, which makes cleaning up and looking good so much easier...

Suspension Upgrade (Part 2)

Anyway, after I finished drooling over the red LC500, I let them take the IS-F in to have the OEM Tokico dampers replaced with the late model OEM Sachs (ZF) dampers.  I was keeping my fingers crossed, because although the guy on the ClubLexus forum swore it was a worthy upgrade... well, the Internet is only as true as you believe it to be.

This time, no GS-F loaner car. However, they did let me borrow this for the day:

IS300h. 

I still don't like how the rear end looks. Oh, and the wheels look tiny!

The interior... well I DID like the LFA inspired dash...

As I had a few chores to run, I actually drove the car into Tokyo. It's a decent highway cruiser, but after the IS-F, I need more POWER!  As expected, the build quality was great, but without the Mark Levinson stereo, the sound quality was just mediocre. Really!

The next day, when I went to pick up the IS-F, I saw THIS parked at the dealer...

No no, keep it!

 The techs had loaded up all the used parts into the back of my car's trunk:

I like the way that, even though my car has an aftermarket rubber mat, they still "wrapped" everything they loaded up with the large white foam sheet. So Japan...(ZF = Sachs)

And the results? The moment I began to drive to leave the dealership, I immediately noticed the difference. Firm, but way softer. Then, I driving home I noticed how the car was able to absorb small bumps much much better.  

Finally, a few days later on the expressway the car was AMAZING on the curves, the tighter it got, the better. What I mean is that, the car before was stiff. Just stiff. So the car would bounce excessively on bumps, and at speed a loss of confidence as it felt a bit unpredictable. Now however as a curve approaches I can feel the outside front wheel "bite" as the weight transfer happens to the outside. This "bite" gives better road feedback and thus more of a sense of what the car is doing. The car feels flatter too, strangely, and better planted to the road.

Don't get me wrong, the car is still very firmly sprung but I suspect the spring rate is a bit reduced and there is longer suspension stroke, at least in the rear.  So, a very worthy modification if you insist on keeping OEM and don't care about ride height.

Update - I just googled and found this article from Edmunds analyzing the changes made to the IS-F suspension. I am pretty sure that when the dealer did the alignment they did NOT give the car the rear  camber adjustment as per the 2011 model, but I will ask next time I take the car in...

Suspension Upgrade + LC500! (Part 1)

Ok ok so I have been very very bad about posting updates on this car - my excuse is that my free time is spent blogging about my GT-R, and getting used to a new job I started in May.  Oh and I was overseas for a few weeks too, back in March.

Excuses aside, after I returned from my trip in March, I decided it was about time I did something about the car's ride. As many know, the early IS-F cars were criticized for having a harsh ride, while some people claimed they got used to it, or that it was the price to pay for the sporty nature of the car.

The problem for me was, I did not want to purchase another set of Ohlins like I have on the GT-R - which as a result was driving more smoothly and more comfortably than the Lexus!  But, while the Ohlins DFVs are superb, they require rebuilding every 2 years or 20,000kms. For a durable car like the Lexus (i.e. Toyota), this was not going to work.

Further, as some of you remember, I been given use of a GS-F as a loaner - and I loved the way that car rode.  Some asking around revealed that the GS-F uses dampers made by Sachs.  Then, I read on the ClubLexus forum that someone had replaced their 2008 IS-F OEM shocks with those from a 2012 IS-F, which also happen to be made by Sachs!  

So I knew a swap could be done, and further, these parts were OEM and thus not as expensive as aftermarket Ohlins! And no need to rebuild! So win-win...

My dealer agreed to do the swap, but told me they could not extend the car's warranty to the shocks, only the warranty for the shock itself would be available. Not a big deal. So I went ahead and ordered, and a few weeks later got the call!

Nothing special about these cars other than the new car smell...

Lexus hospitality can't be beat!

While the mechanics worked to install the suspension, the dealer decided to give me taste of what to expect.

"Go have fun!" they said!

Unfortunately, it was all for nothing. Because a few hours later the dealer called and told me that they had only ordered the shocks and NOT the springs! Oh and something called a bump stop needed to be ordered as well.

Obviously, being the first to try something in Japan means that you have be very patient.  Or, have a sense a humor about the situation, or both.

In any case, I returned to the dealer somewhat disappointed, but then soon forgot about it as I spotted this car, one of the first ones in Japan!

Trust me, looks WAY better in person!

Hard to tell with the black leather, but the interior is ALL leather...and GORGEOUS!

Nice little touch there

My advisor was particularly proud of this touch - the 3-D effect LED taillamps! Hmm, maybe an idea for the GT-R? Lol.

So this initial visit wasn't a total loss - I got to see the new LC500 (and got a free car wash. Oh and got to drive the GS-F around all day...)

Another LED Upgrade

So after one of my turn signals failed, I was too lazy to replace it myself. So, I rolled over to my local Lexus dealer for some (expensive) love.

While they were at it, I asked if they would make an exception to policy and replace the parking lamps up front, with LEDs. Amazingly, they agreed!

The OEM parking bulb is "white" but next to the HID low beam, looks orange-ish.

Thanks to both sources for the photos of the OEM parking lights - I forgot to take photos of my own car, so have to borrow these photos.

Anyway, as the mechanics replaced the burnt out turn signal bulb, they went ahead and installed these:

So 5000K whiteness, and 110LM.

I chose these bulbs because of their high lumen capacity, and also because 5000K is probably similar to the kind of whiteness we now see on modern car's lighting.

The result:

At the dealership, I couldn't contain my excitement. Excuse the lens flare!

Because of the flare, I decided to try again at home:

This time better. Amazing how bright those little LEDs are, except in this photo it's hard to tell anything other than the whiteness

The actual brightness, compared to the other bulbs on the car, is as above. I guess here the brightness of the foglights serve as the primary lightsource for the iPhone camera. Because:

With the foglights off. No, the LEDs aren't any brighter, it's just the way the light affects the iPhone camera.

In any case - the white parking light, adds a modern touch to the car. The only thing left to finish it off would be LED foglights.  And of course, I'm already planning for this. Except, I wonder if there is a way to deal with the orange-ish high beams first?

GS-F Test Drive!

So when I dropped off my IS-F for its 6 month inspection, I took a quick look at the following cars:

The interior looked cheap. Same materials as used in the IS-F? Expected better from a GS!

The look is growing on me. Still think the rear quarter is weird though.

Turbo model! Curious to see how this drives...

 In any case, the next day I went to pick up the car:

And saw this monstrosity...

 But the highlight was when Ishikawa-san pulled this out of the garage:

Check out that license plate!!

Ok so I'm not as well dressed as Ishikawa-san. But very happy!

Forget to take a photo of the ultra-clear heads up display the car has!

Lots more legroom. Love the color actually!

Bit surprised that a real harness could not be passed through...

Same basic engine means, the car feels slower and less nimble than the IS-F

Looks much better though, I think.

Especially with these LED headlights!

Why they kept the brakes on the IS-F black....

Even from the rear, looks great. Hey, real exhaust pipes!!!

Everything in the car is much more refined than the IS-F, as would be befitting a GS sedan, and the power is fine. Not as urgent as the IS-F, but then again we are hauling around another 400kg I think.

What I was really impressed by was the ride quality - Sachs dampers apparently, the same manufacturer as that which supplied the later model IS-Fs.  I may have to eventually replace the early OEM Tokikos with the later model OEM Sachs in my car.

Meanwhile, I have a couple of mods coming up soon....stay tuned!
