I had my GS400 lowered on 20's and it definately rides much better than stock but if you like 22's getting the correct offset and wheel width will prevent you from having to lift the car.

When the VSC light comes on it possibly means some damage has occured to any 1 or more of the 4 speed sensors that are mounted on the each brake caliper. You'll need to run a diagnostic check to pin point which speed sensor it is that defective. The sensor cost appr. $250 at Toyota or Lexus dealer but look on eBay for a used one. The front senors are pretty easy to replace. I'm not sure about the rear sensors but since the sensor has a plug-in harness it make replacement relatively straight forward. DIY and you could save $150-200 labor.

    Lowering a car is essentially lowering the center of gravity thus improving body roll when cornering especially at higher speeds giving you more control of the vehicle. Depending on the rate of the coil springs installed it will determine how responsive the ride will be. I would recommend a 1" to 1.5" drop. Any lower than that will affect the chamber more severely leading to advanced inner tire wear because the wheels will be tilting inwards much more (this condition is called negative chamber). An aligment is highly recommended after lowering the car. I installed H&R springs on my GS400 with the stock struts. It was a 1.5" front and and 1.3" rear drop and still a great ride in terms of comfort. Recommended brands for coil springs are Tein, Tanabe, Eibach, H&R or basically any proven Japanese or German company that makes spring coils. They cost appr. $200-300 for a set of 4 coil springs.

I loose power when traction control light comes on in my 2002 mustange gt

With some makes and models this is normal. The PCM will reduce engine power when the traction control senses wheel slip as a safety precaution until traction is restored

Check engine light on traction control light on cruise light blinking whats wrong?

When you have a check engine light come on, the traction control light and the cruise lights both come on as well. You need to have the codes checked with a scanner. There most likely isn't a problem with the traction control or cruise systems, the lights turn on because those systems work together with the engine management system or PCM. When there is an engine problem that sets a code that turns on the check engine light, it automatically disables the cruise control and traction control for safety reasons. Because the last thing you want is to have an issue with traction control and/or cruise control if your engine is having an issue, which is why they are disabled. The most common problem that turns on the check engine light is a loose, cross-threaded, or snug but not tight enough fuel filler cap. Subaru recommends three clicks of the cap to be considered tight. Also, any parts store can and will check and/or clear codes for free. I hope this info helps!

Changed the transmission 2 times and still the same results the car will not come out of first gear and the trac light stays on someone please help me

Traction assist is a measurement that compares the spin of one wheel to the spin of another. When a traction light is on, it means that the system is activated to make the two wheels spin at the same rate.

Traction control systems perform this in several ways. Some systems use independent braking to apply the brakes to the fastest spinning wheel. Other systems affect the engine so RPM is lowered and a combination of both methods may be used to brake one wheel while reducing engine RPM.

Now the spin counter can be mounted at each wheel or in the differential. Those that are mounted in the wheels are subject to debris like rust or brake pad material blocking the spin counters.

I can imagine the trans being tied into the traction system by limiting the trans from shifting into higher gears if the car thinks the wheels are already turning too fast.

Now I am not a Lexus Expert, but on Mercury systems the Traction Control has an on/off switch. If you go to or and register your vehicle for free. You will be able to get wiring and fusebox details. If the traction control system has its own fuse, pull it.

There is a good chance that with the traction control shut off, the car will shift normally. Then you can drive somewhere that can test the traction control and predict what is wrong.

The traction lock light flashes on the dash panel on my 1993 Lexus LS 400 and the engine shuts off. It will crank up immediately after shutting off at times and some times it won't.

98 oldmobile regency won't start up and check

Well the fact that the traction light came on and blinked off when taking off is a good thing, it just means that your traction control is working properly. When that light comes on it means that one wheel was spinning and that the car adjusted the speed of the drive wheels to compensate. The car not starting needs to be addressed as to whether the car is turning over slowly, clicking, or making no noise at all. The check engine light will remain on until the vehicle is started, so that does not correlate to your problem. If it clicks, or turns over sluggishly, then it just needs a jump start and a test of the battery. If the lights come on, but the car does not turn over al all, then you may need to look at replacing a starter.

What does the TCS Off button do?

TCS stands for Traction Control System.
The traction control system works in conjunction with your Antilock Brake System (ABS) and your Engine Control Module (ECM) or Powertrain Control Module (PCM) or Electronic Control Unit (ECU) (Note that ECM, ECU, and PCM all mean the computer that controls your engine, depending on make.)

Anyway, the traction control system can apply one or more of the brakes and control engine RPM in the event that a wheel slip has been detected by the traction control system.

Pushing the TCS button on most models will light a lamp in the instrument cluster that usually says "Trac Off" Pressing it a second time will turn this light back off.

When the "Trac Off" light is illuminated, the Traction Control System is disabled and will not work in the event of a wheel slip.

Also note that when the Traction Control System is working and a wheel slip is detected, The Traction Control Module will usually illuminate a light that says "Trac" as it is taking control of your brakes and engine. It can feel really strange when this occurs and some people think that their transmission is slipping or that their engine has a misfire problem.
The chances are that if it occurred on wet, slippery pavement, the Traction Control System may have just saved your life.

If this is happening on dry pavement and normal driving conditions (starting, stopping, or turning), there may be a problem with the system. "False Traction Control" can happen just like a bad wheel sensor causing "False Antilock Mode".

Also check your Owners Manual for more specific information pertaining to your particular vehicle.
