LS430 Anyone here converted to springs?

Recommended Posts

I have just taken delivery of a set OEM shocks and springs from the USA to replace my utterly terrible K sport coilovers. Having suffered the appalling ride and bottoming out rear shocks due to totally the wrong spring rate for close to 80k miles enough was enough.

My questions is does anyone have any pictures showing the OEM ride height on standard shocks and springs? Its been 2 years since the OEM air suspension died so can't really remember how it sat (very high at the back and low at the front from memory)

I like the way my car looks and wouldn't want too much of a height increase as I feel it would look rather silly.  The car actually looks a lot lower than it is in reality Never seems to make contact with the ground even on the unpaved roads surrounding our house and would like to keep it looking as close as possible to how it looks now. 

Lowering springs can be ordered and have them installed along with the new shocks to save doing the job twice however I was wondering if I could "get away" with simply installing the standard setup. (Springs would have to come from Japan via Nengun where shipping costs more than the item you buy)

I've considered this in the past but I came to the conclusion I would probably stick with air if a problem should arise.  The normal position is actually the opposite to what you remember with the front always looking a lot higher than the rear.  On mine the height at normal setting is 28" from the ground at the centre of the wheel to the wheel arch and 28.5" at the front. 

If I should ever decide that a conventional setup is the way to go I would, after much research, buy from Strutmaster in the US as they make them specifically for each car. With delivery and prepaid taxes it still works out at only about £1,100 for the set including delivery and taxes. It's a personal thing of course but I prefer the LS to sit at the original height.

Plenty of images on Google. Just search for "LS430 side" and click on Images.

I also prefer the air shocks.
If you buy new Lexus parts then air suspension is stupidly expensive to repair, but there are plenty of used parts available so I'll stick with air thanks. 😁

Thank you for your reply, I will get the measuring tape out and double check 🙂 

As for suspension I have gone for OEM Kayaba Shock absorbers and Springs from amazon.com ($750 delivered) and OEM springs. The non ultra luxury LS430's in the states all got normal steel springs. We only got the air system in Europe 😞 

Front Part number for the shock is 48510-59805  + Top Mount 48680-50110

Rears are 48530-59845 and 48755-50100

I think I will just install what I have and then see.

 

I wanted to double check what the ride height is on conventional factory springs as opposed to air. My air suspension is long gone.

When I checked with strutmaster they said their struts would make the car sit at factory level so I'm assuming both air and coils would both sit the same from the factory.

On the LS400 factory coil and air have different ride heights, camber, toe etc.
