After a LONG Saturday morning, I finally completed my DIY install of the Tein S.Tech springs. Thanks to Kenchan and DrSifu for the help and suggestions.

I only have three pieces of advice (other than what can be found in the DIY write-ups). Make sure that you rent a proper size spring compressor (mine was too large to fit in the front wheel well, designed for cars such as a FWD Maxima). Also, see if you can rent an air-tool (because it makes the job SO much easier. Lastly, if you happen to strip one of the 17MM nuts on the strut, DO NOT waste your time going to Orchard Supply Hardware, Loewe's, or Home Depot as they do not stock this part. It is an automotive only part that can be found at your nearest Nissan or Infiniti dealership.

The install took my friend and I about 2 hours for the first front spring, as we had little idea what we were doing. About an hour and 15 minutes for the second front spring, 25 minutes for the first rear spring, and about 10 minutes for the last rear spring.

Now, onto the pics. These were taken immediately after the installation, so they have settled in a bit more. My alignment is definitely off, but I will have it adjusted next week. The ride is incredible- feels the same as my OEM sport springs did but is more tossable and handles flatter. Next step is sways...

 

Looks clean.

 

Thanks- it's actually much lower than it looks. Part of that may be that this picture was taken before I drove on the springs, and my large 45-sidewall OEM tires look like they are part of the wheel well.

I have a one finger gap between tires/fenders on all four corners.

 

wow, that looks good!!

 

Looks really good.

So the ride really is comparable to the sport sedan suspension? I want a slight drop on our 6MT but like the current stiffness of the suspension. I don’t need another car that rides as harsh as our Saleen. It sounds too good to be true, to get a lower ride height and maintain the ride quality.

Do most sedans with the S Techs align within specs.? What is the published drop?

 

If you are only looking for a slight drop, you may find the Tein H.Tech's to better suit your needs. I have to be extremely careful around town now, and take all sorts of strange angles to get into/out of driveways. The drop on the S.Tech's is approximately 1.9" front, and 1.5" rear. They do not feel at all stiffer than the OEM springs, and for now the OEM sports shocks are holding up well. I intend on switching over to D-Spec's in the coming months.

 

So from the H-techs, I may get a similar suspension feel to what I have now but a smaller drop of around an inch or so? I will be taking a close look at the D-specs as well.

I can’t get over how good those stock wheels look. To bad 245 and 275 tires won’t fit on those rims.

 

Looks awesome

 

Good looking sedan.

 

Which DIY writeups did you use? Where can you rent a spring compressor from?

 

Looks real nice!

 

Agreed. Looks awesome!!!

 

I used this one by DrSifu: http://www.g-owners.com/article_read.asp?id=25

You can rent a spring compressor from any Kragen, Autozone, or similar automotive parts store.

I'll take some more pictures tonight, as it seems that car has taken on a lower, more agressive stance.

 

i had the same springs before, and yes, makes the G look tuff,,,,,,,,now, let it settle for about a week and get an alighnment....and then get ready for a camber kit...the front will be off, due to the 1.9" front drop......as for the rears, they should be able to get it back to specs.....have fun.

 

Congrats! Looks good! Incidentally, today I installed a 350Z suspension into my G35 Sedan... Since I was replacing the entire strut assembly on the front, I think I had an easier time... Some tips for those who want to do this DIY:

1. Getting the front strut out once everything is unbolted is a pain without a spring compressor, but it can be done. I used the factory jack to push the wheel assembly down until I could clear the strut away from the assembly. It takes a lot of trial and error, but a good thing to do is to try to twist the strut out from back to front (I think)... you'll see what I mean... it only comes out one way.

2. Please please please, use a jack stand! I don't want to hear about people getting crushed under their cars because the factory jack failed! The factory jack wasn't designed to handle the amount of force you will need to exert to do this job. It's such a flimsy piece meant to be used only once or twice in an emergency.

Otherwise, G35sedan's instructions were extremely good, and very easy to follow. Total time for me was 4 hours... 2 hours on the first front, 25 minutes on the second front, 1 hour on the first rear, 20 minutes on teh second rear, and 15 minutes more because I was a dumbass and forgot to reattach the speed sensor lines on one of the fronts! (yikes!)
