Back from the dead.. me and a friend tackling this today. Hopefully all goes well.

finshed mine last week it rides good and looks great i wouldnt want to go any lower

Thanks for the writeup. It was very help full this weekend on the GS400. I replaced the struts with some new OEM units. Have to keep it cozy for my wife as it's her daily in the 70 mile a day round trip with our baby to and from work. Also replaced the tie rod ends so it made it a bit easier as I could turn the assembly by hand

Nice write up. Your information was very helpful but I ran into a little bit of trouble.

Today I discovered that one of my front springs has broken, which may explain the vibration I had assumed was engine mounts. It's at the very bottom, so the car is still drivable, but:

Since the l-tuned shocks and springs are discontinued, what do I replace them with?? I am only going to replace the fronts, and I would just replace the spring if I could be assured it was identical.

The Eibach springs are the closest thing to the L-tuned springs.

Thank you so very much for this write up!

Just installed an Eibach Pro-Kit for my GS3 and no surprises. Although the front was a major pain in the *** because I changed out the caster arms as well on both sides, and getting the two bolts to go back in drove me insane.

Anyhow, I used the stock bumpstops in the rear but didn't cut them, and hear some noise =( anyone here have the same issue? Don't really feel like taking them back out to cut the stops in half.

I just installed Eibach springs in the front as an l-tuned replacement, reused my l-tuned shocks, still have l-tuned s/s in rear.

This guide was EXTREMELY helpful.

The Eibach springs are very close, though not identical.

The spring that broke may have had a material defect; a split was visible in the cross-section of the break.

Edit: Why isn't this thread a sticky? It has more views than any of the other sticky threads in this section. Google 'gs430 suspension install'.

Thanks for this guide and the useful comments. I'll be installing my S-Tech springs and KYB shocks soon.

This is some very helpful info,I will be looking at this thread when I'm ready to drop....

Guide helped a lot. The rear is harder than front...it's just a lot of wrench turning and lining things up. I can see how this is $500 in labor. I like to go slow, clean, and lube all chassis points. Strong sockets are a must..any kind of play and you will strip bolt on the big ones.

This is a very helpful write up. thanks for putting this together. Worth its weight in gold

I'm tackling this this weekend!!! Back from the dead. Any other tips or tricks from others? Can I use that puller to replace the lower ball joints while I'm down there? Can't I simply put that on one end of the lower control arm and the other on the ball joint and use a ratchet to push the ball joint out? And the cars weight to press it back in place??

About to try to replace my shocks. How do I get to the top of the rear shocks, do I need to remove the back seats?

Revive. DF210s just came in today. This has to be one of the greatest DIY threads ever.
