Default 01 is300 wheels

A buddy gave me a set of stock is300 wheels. 17s would they fit on my 99ls?

Look exactly like these

no they will not fit as they will not clear the front brake calipers, unless you run spacers.

more in the FAQ:
https://www.clublexus.com/forums/ls-...questions.html

-OEM Toyota/Lexus wheels that clear 95-00 big brakes (5x114.3, 60.1mm hub)
95-00 LS400
01-06 LS430
06-11 ISX50
06-11 GS350/430/460
93-97 Supra Turbo (only)

NO OTHER OEM Lexus wheels will clear.
LS460 wheels do not fit They are 5x120 and will need an adapter.

if installed correctly they will be fine to use on our big body chassis!

there are many to choose from but i had great success with ichiban, though i'm sure there are other copy cat brands out there for cheaper.

i would not go beyond a 5mm spacer on the stock wheels studs.
they have a version-1 and a version-2 spacer, depending on size of spacer you need.

All of those choices will lead to a smaller OD, which means your speedo will be off.

Smaller od? I used that calculator....says 55 will give me accurate odo. But it's already behind 3mph


I'ma go with 225 55 17 but been looking for what size spacers is needed.

225/60/16 is the stock size, so yeah your list of sizes will be off by a few mph. You need 245/50/17 or 225/55/17 to be pretty close (<0.5 mph @60).

As for spacers, I'm not sure. Others are typically right though, clearing the brakes is a pretty important thing for rims on this car. I'm not sure if those will clear them.

Use http://willtheyfit.com and make sure your new wheel diameter is the same as the stock LS400 wheel diameter because you'll run into clearance or mechanical issues otherwise. As for the spacer, I believe a 20mm bolt-on wheel spacer will suffice to just barely clear the front brake calipers. Now, unless you bolt-on the same spacers in the rear axle too, your look is going to suck and you're just going to be adding more points of failure just to rock IS300 wheels and make it look decent.

However, the effort gains you little reward in my opinion. With the money spent and effort, you're just going to end up with an LS400 with IS300 wheels. There are lots of wheel companies today where you don't have to use a wheel spacer. You'd get the benefit of running wider track width and sportier tires by also going up a wheel size like 18-19. They usually aren't very expensive either- I would recommend you look at your options first to make your car look the best unless you are really just aiming for IS300 stock wheels.

Definitely check out your options because the game has changed in 2020 bruv:

i'm not certain what size you need. you might be fine with 5mm but 25mm might be overboard and look too hokey.
if you have the wheels already, why not do a test fit? you can use plain old washers to get an equivalent size - of course do not drive on them!
