Anyone ever weight there 07-09 ls460 base model I did a custom exhaust on mine and tossed the spare along with trunk carpet cover ,tools I believe I've gotten close to 200 pounds out of the car without messing with any interior or buying any expensive aftermarket wheels or seats im honestly curious what these cars weight after a few mods.

 

Unless there's a bunch you're leaving out, you're nowhere close to 200 lbs.

The spare and tools, really everything in the trunk is around 50-60 lbs. Does your exhaust delete the 4 cats, 2 resonators and 2 mufflers? I could see another 50-60lbs with all those removed and replaced with straight pipe.

 

The best way to reduce weight of LS460 is to sell it and get something that better fits your "needs".

 

I've been a member for a long time and don' t think anyone has posted how to lower weight. But try a search. The car weight can be searched online as part of specs.

 

So I had my exhaust done at a custom muffler shop we deleted the stock 34 pound mufflers stock ls460 mufflers are 32-34 pound each crazy they cut my exhaust behind the first cat flange and ditched the old stock pipes secondary cat delete 2.5 inch piping leading to a 2.5 inch x pipe then straight to the bumper , as far as the trunk goes I weighed the spare rim tire alone weights 57 pounds on the scale oem jack n tools maybe another 10-12 pounds my trunk is Farley gutted rug Matt probably another 10-12 pounds also ditched the engine covers wich were only 8 pounds untuned I ran a 13.6 with crap tires on draggy an only got 1 real good run on the roads I tested on out of 3 passes compared to some tuned ones on YouTube and with shorter rear end ratios than stock I think 13.6 is pretty dam good for a stock boat I actually have plans of doing a full build on this car big rims tires bigger breaks procharger the whole 9 would like to see 600 hp plus on the stock block I have a spare low milage engine and a shop that can build n tune it for me.

 

Is it a full size spare? the stock GS wheels with tires are only 51lbs lol I didn't think the LS spare would be bigger than those.

Well if you want to go faster, you're not going to want big rims, some lightweight wheels and sticky tires, and some coilovers can save quite a bit of weight. Keep it up, you might make an LS that can run 12s.

And don't just mention the dragy! It means nothing unless you actually post the slip.

 

At one time you could "go fast" with this but it is no longer available.

cArBon FiB3r!!! (Jk). The OEM seats weigh a ton, if you fit lightweight racing buckets you'd probably make up some decent weight. Other than that pull the entire interior out.

 

You can also lose weight if you aren't fit, and if you want to go fast keep the tank 1/4 full and just keep refilling it when it gets to 1/8.

 

That's one hell of a sentence...

 

The worst part of the Lexus community is how quickly we give up... I'm on the same weight reduction quest. I've ditched my air suspension for coils and switched to a lithium battery. I've also swapped to the lighter f sport wheels. I plan to ditch my spare as soon as I can build my tpms sensor tube. Wondering if I can pull the air compressor without throwing a code . I've also been researching the rotors from the new LS 500 as they appear to be a 2 piece design. Not sure what my ls600 runs but with the few mods I have, it keeps up nicely with my friends modded b58 5 series. Just ordered rr racing pulleys so things should get even more interesting once those are installed.

 

Eh, I generally avoid calling people out on forums, but I'd like to see more proof.

I drive a LS600, but previously have owned E90/E92 3ers and a F10 5er with N54s and N55s, and a V10-powered E60 M5 for kicks. Either your friend sucks at "modding" or they're being nice. I love my LS, but a sports car it ain't. In the heaviest, xDrive spec the G30 540i puts down ~330 HP for less than 3,900 lbs. Meanwhile, the LS puts down 430 HP in hybrid guise for 5,000 lbs curb weight. The G30 is .084 vs the LS .086 power-to-weight, setting aside driveline and transmission differences. A B58 can simply be flashed to 20 to 30 more HP, no supporting hardware required, bringing the G30 to 0.092. Much larger numbers are easy with a larger intercooler, exhaust, and E85 fueling. Meanwhile, losing 200 lbs on the LS only gets you to 0.089.

Don't get me wrong, I love crazy passion projects, but forced induction will always be the easiest path to big gains.

 

Remember, the b58 is pretty underrated in terms of power, many owners have reported well over 300WHP from completely stock b58 cars.

I'd take it with a grain of salt, lots of dudes in these forums need to inflate their egos, however it's totally possible that he's got 500lbs of weight reduction and 50hp in bolt ons/ tune.

Either way I agree, a modded b58 car shouldn't be that slow, but Dragys only like $150, and it doesn't lie. Would be awesome if we could see some fast LS on there.

 

I don't tend to look at it like giving up. I think the many owners look at it through a couple lenses. One lens is sort of like a "bang for the buck" kind of lens. The other lens is a "what is the purpose of this car" sort of lens. At least that's kind of where I come out.

And my thinking is, I could spend substantial money lightening and trying to add power, only to get spanked by a stock Civic Si (or whatever the fastest Civic is called these days). I'm not saying a stock Civic Si would win, I'm just saying that's an example of a frustrating way to shed money. And 2, the LS excels at being a big smooth trouble-free land yacht. That's why I bought it in the first place. Do I really want to change it from that? More power to you if you do! But I think that's why most choose not to go the route you may be traversing.


Are there really bolt ons and/or tunes readily available that yield +50 hp? Or were you being hypothetical? I guess it's possible, I haven't been paying close attention lately.

 

You will obliterated by German luxury cars if you try and be fast. Don't even try lol! Even a max effort LS isn't going to run 10s like a bolt on A8 will, that's why I left Lexus......if you are serious about making a fast LS get a 2013 SWB AWD, pull the engine and lower the CR to 10:1 or less and put the elate supercharger kit on it using a good super headhunt.

So after spending around 35k for a nice car, 15k for a build you should make around 650hp and you will be annihilated by an A8/S8/S6/RS7 that is putting down 720 to the wheels on stock internals or a 4.0 S-class doing similar with even more luxury features to add insult to injury. Oh for 10k less than you paid as well so it's not even practical and those cars by default come with far nicer/better brakes, suspension, cooling, and MUCH stronger drivelines and WAY better transmissions. Stock.


Just enjoy the LS460 for what it is, an extremely soft, comfortable, quiet, excellent example of the Japanese way of designing a car. I seriously considered a build on my 07 until I just stopped and reminded myself how pointless it was vs just continuing to enjoy the Germans, now I am just looking for a 2009 LS600hL with the full rear seat so I can have a nice complementary car to my W12
