Q: Coilovers and Sway Bars 2002 Lexus IS300

asked by on January 18, 2017

Hello,

I recently purchased a high-mileage Lexus IS300 and would like to improve the suspension.

How difficult is it to tune coil-overs and install new front/rear sway bars?

My car has 194000 miles.
My car has an automatic transmission.

Hi there - upgrading your suspension with coilovers and sway bars is not terribly difficult, and is largely an "unbolt the old, bolt on the new", followed by an alignment. It does, however, require appropriate equipment to raise and safely suspend your vehicle while you work underneath it, always an important consideration! There are several tuner suppliers providing these parts. Don’t get carried away with selection of "race track" vs "sport" levels of firmness unless this will be solely a track day car, or other high-speed driving event vehicle. Happy motoring!

While I was driving the car felt like it went into neutral even though it was still in drive.

Sounds like the automatic transmission might be failing. The mileage and age are about right. If there is a dipstick, you can check the fluid yourself, but many cars made after the late 1990,s don't even have a dipstick you...

does driving a car at 4000RPM with a limit of 8000 rpm cause harm, after the car is at operating tempurature?

It should not harm your engine to run it at 4000 rpm. With this high of miles, however, I would not run it for an extended time at these speeds. Especially since it's an older engine.

When the car is in idle it vibrates and rpms move up and down when idle.

What you are describing is a category of inconsistent idle. The underlying fault may exist at higher engine speed but the effect is masked at those higher speeds. Among the potential underlying causes are vacuum leaks, EGR system malfunctions, malfunctioning...
