Tein S. Tech
Anyone here have a set of S. Techs on their G coupe? I just purchased a set and wanted to know if anyone here had any pics of it installed....and also if you had any alignment issues. thanks

Should have gotten Z H-Tech's. Its a great drop IMO. Its what I have however the G S-Tech's are gonna be pretty slammed. I think thats a 1-1.1" drop all around while I'm at .8 or so I think. Doubt you'll be able to get your alignment back into spec with that.

i plan on getting the camber kit very very soon....its 1.2" up front and 0.9" in the rear....not too bad at all. I was already measuring with a tape measure and 1.2" isnt that bad at all....it will still have a tiny gap.
what's the rate on the S-Tech? I remember the G tein spring have sucky spring rate. I got the 350z h-tech in my trunk right now. Can't wait to put it on. Also, them camber kits cost an arm and a leg!! I'm trying to avoid that route at all cost.

First off, the OEM rates are; OEM Spring Rates F: 314
R: 342
The Tiens are, from what I've found on-line; for the G-35 NOT the 350Z
Tein H-Tech
F Drop: 7mm (.3in)
R Drop: 4mm (.2in)
F Rate (324lb) (+5%)
R Rate (260lb) (-22%)
F Progressive
R Linear
Roll Stiffness Transfer: 27% to front
Tein S-Tech
F Drop: 17mm (.7in)
R Drop: 14mm (.6in)
F Rate: (358lb) (+14%)
R Rate: (274lb) (-18%)

Roll Stiffness Transfer: 32% to front
OK... now somebody that knows needs to chime in here as to why in the name of heck they have made the rear end so soft in the G35's? The 350Z's are 3% to front and 7% to front for Roll Stiffness Transfer. I've gotta' tell ya', the rear end of the G's doesn't need to be any softer, especially if the car pushes.
If you want the front to bite better, you make it softer and the rear harder, that's old school basics. Now of course you can do it this way and perhaps leave the stock sway bar up front and put a stiff one on the rear and you'll have less body roll in the front and let the springs do the work. Where if you put a stiff sway up front it's just going to make it push worse. Perhaps they are also thinking that they'll go with really soft springs on the rear so that no matter what the road conditions you'll have an easier time getting the rear end to stick, even if it's really bumpy. Then you put an adjustable rear sway and really crank up the rear percentage over stock and the front push will go away in an instant. Allowing you to steer with the throttle fairly easily.
What is confusing to me is traditionally there have been two schools. One believes in hard springs and soft sways. The other believes in soft springs and hard sways. With the Tein springs you're going to have to have BOTH. One end (the rear) will be really softly sprung, (which may do a lot to help wheel hop and keep the rears planted) yet have one MOTHER of a sway bar. Although I worry about it sagging a good bit under power.
Then the front will be fairly stiff on the springs, which keeps the car more level yet adds to the push, but really plants the tires. Then you put a medium to light sway, which you'll have to play around with to find the balance where you'll cut out body roll to keep from adding to the push that is known to be there, and hopefully find a setting that allows the rear end to be more throttle responsive. (Without making it loose as hell.) Remember, 99.9% of the drivers out there would rather have a car that pushes (is tight) than one that breaks loose (is free) when they are flying down a 2 lane road doing 85, AT NIGHT!

The theory being if it's pushing, you'll have time to let off and gather it up before you back off the road into a big oak tree. I'm just not sure about 27% ~ 32% more push as that seems a bit extreme unless you have a really sweet (IE spent a lot of time tuning and testing it) sway bar setup to go with it.
Just my 2¢...
Anyone else?????
