Question Options that I never heard of?

While surfing the Lexus parts catalog, I came across 2 available parts that I never knew exist, want to see if you guys know about these?

There is 2 different kind of radiators, it is label "with or without trailer tow". The with trailer tow one is $100 more. It make sense that the towing package would have an extra large radiator for the higher load, but my question is, anyone ever seen a towing package from Lexus for the LS430?

On the suspension, ignoring the air struts, for the conventional steel springs, we all know there is a sport package, but within the sport package, there is also something call a "rough road spec"? I am guessing it might be a softer spring or it lift the body higher. But the same question, anyone ever seen a LS430 with a rough road spec?

The first one is standard in hotter climates (ie Middle East) due to the extreme weather.

The second one i suspect is due to bigger anti-roll bars if im not mistaken.

^^^ bar-- meaning only the rear, right? I wonder why they don't have one for the front.


Not until you brought it up Jeff

If that is true, they would label it as a "hot weather package", but they label it "with trailer tow", making it sounds like a towing package.

I don't feel they are related. The sport package come with a bigger rear sway bar, but Lexus listed 2 different springs for the sport package, with or without "rough road spec". So in total, Lexus offer 3 different kind of steel springs for the LS430:

Regular
Sport package without "rough road spec"
Sport package with "rough road spec"

I am pretty sure noone knows about all these, as the Lexus parts guy I just talked to didn't even know the sport suspension exist until I pointed it out to him. I figure I ask anyway, but it is not important, is not like my car need a bigger radiator or springs to travel on rough road.

Yeah only the rear bar is bigger on the sport, but I am not asking about that, I am curious about the "rough road spec" sport springs.

Because Lexus engineering feels the front bar is big enough already for the sport suspension, and I feel the same way, go look at the front bar you got now, it is HUGE! I am sure Lexus think if you want it bigger, go call TRD

Well, that's Lexus. We all know that they weren't sport oriented in the beginning-it's all about cushy luxury
That's why I went with lexus

That reminds me...I need to get an oil change. I'll definitely be looking for that big fat bar. I'll see if I can coordinate to getting that rear bar and bushings to get it installed while I'm at it.

You got that right.
Plus, there's not too many aftermarket stuff for the LS (thank goodness) as compared to the GS

Exactly. If I want a sports car, I would have bought a sports car

Please tell me how that bigger rear bar feels, I think you'll beat me to it, I have to put in the shocks first.

Actually, there is just as much aftermarket stuff for the LS as compared to the GS. It is just that it is not popular to mod the LS to be sporty here in the U.S., so the vendor don't bring them in, which give you the feeling of nothing is available. But everything is available in Japan to turn a LS into a race car if you want. A set of coilover with the TRD sway bars and throw on all the stiffening braces, the LS can handle just as good as the best modded GS. The weight difference between a base model LS430 and a GS430 is pretty small, about 200~300 lbs, so with equal amount of mods, the LS can perform just about as good.

Tow package, now that's an idea. I can ride in the car and tow the in-laws so I don't get the normal earful on long rides... ha ha. j/k.

"Rough road spec" must have been the NYC/BQE package. Must have had a pothole sensor linked with the radar cruise.

Can a larger sway bar be added in the back to give the LS sport suspension like from the factory? Thanks

Well the larger rear sway bar is just one piece of the pizzle on the sport suspension, adding it alone won't make it totally feels like the full sport suspension, but you are one step closer

Like most car manufacturers, Toyota offers different options and accessories in different markets. Occasionally options sneak into the U.S. market catalog even if they are not available here. I've noticed that non-U.S. options are sometimes described in the U.S./Canada versions of Lexus repair manuals. For example my 00 LS400 manual shows the components of the power/heated rear seats for the Taiwan market.

The "rough road" option was perhaps meant for less developed countries where the roads are especially poor.

It is sometimes possible to see information on non-U.S. market options and accessories on the Lexus websites for other countries. A few minutes ago I looked at LS options on the Slovenia which shows one of my favorite non-U.S. Lexus options -- the Lexus Complementary for Bluetooth phones which appears to be the "Bury System 9" rebranded with a Lexus logo.

A fun website is the "techinfo" website for Europe - http://www.lexus-tech.eu - where you can see some interesting information without paying for a subscription ... including installation instructions for adding all sorts of stuff to an LS430 -- Canoe racks, bike racks, trailer hitches, headrest monitors, the Bluetooth Complementary Kit I mentioned, etc.

One of my pastimes when traveling outside the U.S. has always been to look for the weird $#!+ options available on cars in other countries.

Same here.

That is what makes the whole JDM thing so interesting, it is because we don't have that stuff here.

That is for when the gas cap's power latch breaks, you can still put gas in the car to keep it running.

If the battery is dead, you don't need gas anyways
