Built for Comfort

[scottryana]

Let some air out of those duratracs, I run mine about 33psi, so much better driving then the 45psi the tire shop put in them.

Here in Southern Ontario we dont have to many places to go wheeling so there was no reason for me to go with lift and bigger than 33 tire when LC spends 99.9999% on pavement.

So here is changes i did on my LC since i got it:

135K on old tired suspension with P tires -- to soft and bouncy

145K changed to OME 861/862 with OEM TOYOTA shocks and the same P tire --LOVED the ride. It got stiffer but not to much. In my opinion was perfect ride

155K Changed P tires to LT (Duratrac)--Ride became very harsh compare to P tires. I have 42PSI in them which should be perfect for the weight of stock 80 according to P to LT PSI conversion chart.

165K Changed every singe suspension bushing with OEM and ride got better and much more stable on highway but i still can fill the harshness of LT tire -- Overall not bad, but i want to see how my 80 will ride with new bushings and P tires. Oh well, it probably wont happen any time soon as i love the look of Duratrac and their traction in snow and half frozen mud(dont ask)

Not long ago i had to move all my tools from cottage to a storage place 300 miles away and i had easily around 750-900lb in LC and ride was perfect like a LX570 on sport mode i drove for 2 weeks prior the move, plus i had AIR LIFT bags in a rear at 30PSI.

So my suggestion if you want to keep your ride comfortable stay away from LT tires unless you have a lot of weight to carry, but damn that will limit you to fewer choices for you LX.

I hope that helps.

His pressure is close to correct. When switching from a pmetric to lt tire the pressure needs to br increased about 8 psi to make up for the different load curve of the lt.

Sure if the load capacities of the two were the same, the E rated duratrac is much higher thus the need for less pressure to maintain the same load.

Stock tires P rated have a 2601lbs load rating at 44psi

E rated truck tire is rated for 3860lbs

I'm a little late to the party but here's my observation after driving a completely stock, pristine '97 80 series to the Rising Sun swap meet last weekend. The WORST mileage this vehicle got was 17.6mpg and the best was 19.8mpg. Yup, I kid you not, almost 20 mpg! Maybe it was the fresh coat of wax? I forgot that these things can actually accelerate up hill when you don't mess with them to the extent that we do.

If you're not into serious/stupid wheeling, perhaps change the suspension to suit your needs and keep it low.

Flexy-Coils

Flexi-Coils might be just the ticket. They're a progressive rate spring with long drop (allow longer shocks to be used), and they are available in a stock height option. I believe they come in 0.5" increments up to 6" in multiple weight ratings. http://www.suspensionstuff.com.au/shop/index.php?cPath=26_51

Someone is trying to put together a group buy here: https://forum.ih8mud.com/80-series-tech/603287-exspession-interest-flexi-coils.html

Just keep the stock springs and shocks, lift it 30mm front and rear (or less rear if you want to level it). I'm running 30mm front and 15mm rear spacers with 285/75R16 tires. I use stock springs and shocks, and put 1.5" Spidertrax spacers at all four corners as well. It rides really well. I think 45mm front and 30mm rear spacers would be better with this tire size, and 1.25" wheel spacers better.

I think this is the first time in Mud history that the community has talked someone into not spending money.

Lol'ed at this.

Bump this back up to the top for more opinions, I'm looking for another new LX450 to build as an asphalt queen not quite as extreme as LX_TREME rig but ultra-quiet and smooth. My current one has been promised to by buddy for his wife.

In my experience, ride comfort is more directly linked to the dampers than the spring rate. Most of the low lift OME springs are low spring rate of ~220 lbs.in. so coupled with nice dampers will give you the ride you want.

If you want to keep it low n soft consider trying a set of stock fit Koni dampers and either the original springs or some OME "stock height" springs.

In my case I'm looking for that cushy ride, but wanted longer travel. I'm currently running Fox 2.0 reservoirs and working on the damping rates. Will report back when I've got softer compression valving installed

10 years later I’m back to this build again with a turbo or TRD SC. What’s the latest thoughts on best on road performance for a LX450.

@Feldrian has a sweet LX…he might be able to give you some ideas.

 

[Feldrian]

The Wit's End turbo is pretty well supported. Definitely the route I'd go if I was looking to squeeze more performance out of the original engine.

I was hoping you’d show your fancy engine. It having a little pep and whatnot

Judging from the original post - I was assuming we weren't talking V8 conversion.

If that's the route you want to go a crate LT1 fits nicely.

He mentioned turbo or SC and then asked, “What’s the latest thoughts on best on road performance for a LX450.”
I thought of you

Lovely engine bay btw

Well then there is this…
Not really looking to engine swap but optimize the original config with a power-adder. I’m leaning towards the Wits end turbo.
I found an LX with 4.56 gears that are fresh with OME stock height springs and shocks. It’s looking like a great base to start this build.

We’ll it was a good excuse to see his goods, so to speak.
