With the new Tein CS out, I'd suggest those at ~$1,250. Get the EDFC for $350 more and it's a great combo.

Your wheel/tire combo is heavy enough that the softly dampened GR-2's IMO are not a good match. Even the Bilstein HD's don't IMO match well with my 18's and this combo weighs 52#'s. I hope to add the Tein in Feb-Mrach '07.

Like what RA40 said wait for the new Teins that are coming out if your budget allows for that. If not, go with the L-Sportline springs (Eibach made, with a more aggressive drop).

IMO, forget the H&R's, they are harsh (I've had them on different cars in the past) and as far as the GR2's, I don't think they can handle lowering springs. Maybe for a while but they'll bottom out eventually.

Ask member steveski, he's running H&R's w/ Bilsteins and a Tom's strut bar. GL!

In a perfect world, we would all have 17lbs. 20" in rims but not everyone can afford that. I guess what I'm trying to say is, you gotta give and take sometimes? Bigger/Heavier wheels = better handling, better looks, better looks (Did I say that already?). LOL!

No offense to RA40 but if I wanted to watch the unsprung weight on my car, I would have gotten a Civic with Spoon wheels. No need to drive fast in a huge LS400 anyway....

None taken.

The effects of the increased rotational mass on over all performance has been well discussed. In everyday...this will effect your ability to brake. On first gen's where the caliper is not as effcient for a car this size, a 60#+ wheel combo further inhibits stopping. Whether that ads 4' or 12' in ones ability to stop from 45-65 MPH can be serious.

We generally forsake the balanced design the engineers came up in the desire to achieve a particular look. Some mods have minimal impact while others can have significant changes. YMMV and as I said, IMO.

The book replacement Bilsteins also have two snap ring settings so you can get an additional 1/2" drop if you use the lower ones. Also, your car will not have an even fender to wheel tire gap. So if these little differences bug you, don't put springs on it.

On mine, the front difference from left to right, is 1/8" Not a big deal there.
In the rear from left to right, the difference is 1/4-3/8" depending on how much gas is in the tank. This has bugged me a bit since day one. After spending about $1K for the springs+strut+install, I wasn't going to go right out and spend another $2K just to solve that. (I've got about 35K miles on the springs/struts and I'll make the change after I feel I've driven it enough. )

Here's an older pic of mine so you can see what the Bilstein/Eibach pro kit combo is like:

Get coilovers and never have a regret . It is the closest to an LS ride you can get being lowered.

My suggestion...save up. The Tein's ride quality is echoed through this site.

Absolutely fantastic information. The information on rotational weight as it relates to stopping distance is huge. I always thought if the overall diameter combination stayed the same it would not affect the stopping distance. The rotational weight is far more important to think about. I have a second gen LS with 4 piston calipers.

I went with a staggered offset : RUFF wheels (cheaper and heavier at 27 lbs.) and am happy with the look. Next time I will go for better rims -- thanks for the great information!

Hey steveski -


How's that Tom's strut bar working out for you? Any noticeable difference? I noticed body flex when I lowered the car, as expected. Did it solve it somewhat.

Sorry for the long winded reply but I had some major body flex also after lowering it with stock struts. Since installing the STB the car is really much stiffer even with the other suspension mods. I really am enjoying the ride now. With the H&R springs, the Bilsteins and the STB, the car drives way more aggressively

Not sure how much the wheels make a difference but I am running a staggered set of 18's (275's on rear and 245's on the front) with NITTO tires.

I will add an ADDCO rear sway bar next. That will stiffen the rear. My buddy with a Pontiac Firehawk drove my LS last night. He said he was blown away with how well the car handles.

Just in case you get one - you may have to jack the vehicle up a few inches to install the brace like I did.

There's a pic of the STB installed in my gallery.

This is a nice bar!
Just to make it easier.

Just to note, anyone thinking of the Tein CS may not be able to use the EDFC with this bar.

Technically yes - It is from Tom's Racing (box came with Japanese markings). I bought it from Gordon a call at Carson Toyota. It is really heavy duty as you can see. The car handles fantastic.
