I don't think any Lex ever had less than 16's from stock, which would suggest you can't run 15's, even with stock brakes.

15" wheels on LS400?stealthstylz

Is this some sort of ploy to get a set of drag radials on the back given recent events? Haven't you got a wheel you can try on?

I thought I had no 4.5" PCD 15s in the collection but I think I have some 15" Cragar unilugs I could try on there.
With a best 60' time of 2.3 sec I wondered if I could stand to lower the gearing a little as well as put some slightly stickier rubber on it. Crosses the line in 3rd as it is.
Not that I'm going to get into racing the Lexus, I just ran it as the Plymouth isn't ready and I thought it would be fun to see what it did.

It was a lot quicker than I imagined, can see the appeal of using the engines now would be easy 13s in a lighter car.
I'd just try one on. Most people are going for bigger wheels with that type of car can't imagine anybody else down sizing.

The book says 0-60 in 6.7 so I reckoned a low 15 was about right. Its still a fair result from a 2 ton saloon car with "only" 280 BHP. That motor would definitly motivate a lighter car with some fine results.

Mine is 1999, and has the "dynamic handling package" which may include larger brakes. Mine certainly has the biggest brakes they did on an LS400 (same as the Mk4 Supra TT more or less) which makes me think that 15s probably won't go on, although I only need them on the rears, obviously.

This is a dumb question... but one I've never actually remembered to ask...
Changing wheels to a smaller size (radius/circumference)... does that make the car accelerate faster or slower???

as an indication of size, IIRC golf mk4 front brakes are 288mm discs with a floating caliper and 15's fit. 312mm discs with a brembo 4pot caliper needed 17's

It will have no overall affect if the tyres compensate for the difference But year, smaller overall wheel+tyre diameter equals more acceleration. Some Mini's in tight sprint events went down to 8" wheels!

akku, the brakes will be bigger on the front than the back, non? if so, the 16" wheels may be a minimum for the fronts, but not the rears wide 15's on the back, spacesavers on the front?

thats what I was thinking. Although mine has 17s as part of the "DHP" option/edition and may have larger brakes as well

It will have no overall affect if the tyres compensate for the difference But year, smaller overall wheel+tyre diameter equals more acceleration. Some Mini's in tight sprint events went down to 8" wheels! In gear acceleration increases as a result of torque at the contact patch increasing. If the torque (force) at the contact patch is already equal or greater than the frictional force you wont be increasing the acceleration, and if it means you have to take an extra gear change then that will slow you down a little too.... its not THAT straightforward

Nothing is straight forward if you hyper theorise it. All I remember is that with Mini's you stuck smaller diameter wheels and tyres on and they accelerated faster and lost some of their top speed.

acceleration is quicker as for every turn of the driveshaft, the rolling radius is shorter, same result as putting close ratio gears in. of course this is entirely dependant on achieving grip.

and I have RPM to spare at the checker board so its not a problem. Getting the 60' down is more of an issue

I can't think of one road car with bigger back brakes than front, not just lexus. Even when the rear brakes are a combination of disc and built-in drum for the handbrake I can't think of an instance where the fronts are dwarfed by the rears. I do like your getting all serious about taking the beast up the strip, it shows willing
