I wanted to share some information about my recent Tanabe NF210 coil spring install to help anyone who may be looking at installing these lowering springs on their LS460.
Tanabe NF210 Springs - $250 shipped
Labor for spring install - $250 (yes, that is correct. PM me for the hookup if you live near Orlando)
Lexus +2mm Front Control Arm Brackets (4 pieces) - $140
Install for brackets - $80 (will explain later)
Post install Alignment - $80
Total costs - $800
Seat Removal - appx 20 minutes
Springs - 4 hours (includes some breaks for rain to pass over (lift was outside)
Control Arm Brackets - appx 1.5 hours (will explain later)
Alignment - 25 minutes
For reference, I have a SWB LS460 non executive with power recline/cooled/heated rear seats.
So, I had these springs installed and for the most part it is pretty straight forward if you have done suspension work before. I didn't really have the time to do this myself, so I received a referral from another CLer to use his mechanic while I was in the Orlando area.
The rear seats have to come out along with the C pillar interior panel piece covering the speaker, the trim piece running down along the seat on top of fender well and the rear door kick plate. The front of the seats lift right up and come right out after disconnecting the power connector. The seat back has two 10mm bolts on each side that need to be removed. Then, you need to lift up and then forward to get the gear off the track. Store in safe place and use gloves to remove seats. Place them on a nice clean blanket inside or something. Search youtube for "LS460 seat" and there are a couple videos showing how its done.
As far as the installation of the coil springs, I will not get into that entire piece of it. Bottom line, although I have done spring installs in the past, I am glad I didn't do this car. There are some bottom plates that need to be removed along with a bunch of small bolts, etc. For $250..I had to take advantage of that price, especially when the dealer quoted me $1600 LMAO! Other shops quoted 6-8 hours with costs near $700 with alignment. My install took appx 4 hours which includes breaks for rain to pass (shop has outside lift). My installer has done suspension work on LS460s before and I felt comfortable knowing he would know exactly what to do.
Once the install was completed, I took it for a test drive and was amazed at how nice the car drove. Tanabe advertises a 5% ride quality difference and I would have to agree with their estimation. You can tell the car is dropped when cornering, braking or hard acceleration, but while just cruising, it rides damn near stock..gotta love that..its the perfect level of sport and comfort I wanted. I pushed the car pretty hard on a long curved on ramp and there was hardly any body roll..I know before the springs, the car was very floaty on that curve..it felt solid with the new springs!!!
Next step was the alignment. The shop was across town which was good to allow the springs to settle down. They completed the alignment, but as I anticipated some "red" numbers remained on the alignment sheet involving front camber. The shop pulled up the +2mm control arm brackets that can be replaced and recommended I get those to help get camber numbers closer to stock.
So, I ordered and received the OEM Lexus +2mm control arms and got them installed about 100 miles after initial spring installation. In hindsight, I should of had the control arm brackets in hand ahead of time during the initial spring install because there are a couple of bolts you cannot remove unless you have the strut/spring assembly out. So, I paid an extra $80 to get those added after the fact.
The non adjustable Lexus +2mm control arm part numbers are as follows:
Number 1 brackets -
Number 2 brackets -

+2mm brackets Installed on my car, but had to remove strut to do it..sigh
After springs were installed, I had it aligned. Here are those alignment results along with the 2nd alignment once I installed the control arm brackets.

As you can see, there was only a slight improvement with these +2mm Lexus control arm brackets. Perhaps a true adjustable camber kit for the front will become available but I can live with these specs since this is not my daily driver. Any change that helps get back to specs is a win for me, so I'll take it. I'm all about maxing out tire life if possible.
* The car rides extremely well on these NF210 springs. I am very pleased at the ride comfort which I feel is appx 5% stiffer than OEM ride quality
* If there is not an adjustable aftermarket option, I highly recommend purchasing the 4 lexus +2mm front control arms and have them installed at the same time you install the springs to avoid paying additional costs. The four parts should run you about $150 or less total. In my case, they didn't quite get me to all green on the hunter alignment machine, but it was better than before I had them.
* I recommend getting an alignment within the first 25 miles after getting the springs installed. This allows the springs to settle down some. Try hitting some roads with dips and hit some turns a little hard. Then go get the alignment. This is just something I like to do, but in the past, this has worked well for me.
* On the fence about Tanabe's? No worries, DO IT!!
* Special shout out goes to fellow CLer Shibumi1
for referring me to his excellent Orlando area mechanic Justin who did my install along with providing a great place to do my alignment, plus coming by during the install to help out with the rear seat removal. Appreciate you man!!
Again, I create long posts like this to try and help answer questions for my fellow LS460 CLers. I know that I dig through tons of posts to find info when I am researching mods, so I am just trying to do my part to help folks out.
