The Tein H-tech springs for the G Coupe are advertized to lower the front approx .61 and the rear.31. Tein says they are slightly stiffer front and rear. Can anyone verify the amount of lowering and stiffness compared to stock, and are you able to re-align to proper specs? I live in California where we have hills and bumps. I am not interested in "hammering" my car. Max lowering .7 front and .5 rear is plenty for me. Any photos? And, what sway bars would be best in conjuction with the G H-techs? Thanks!

 

My avatar is a pic with the H-Techs installed. Conservative drop without any change in stock feel. I'm happy with them.

 

It seems like most people feel they would have liked the car to be lowered the .6 front and rear. Mine came down .75 front and .3 rear, measured at the front and rear of the car. The ride seems stock, even though the rear springs are softer that stock.

 

Pedal Pusher- did you have to order a camber kit for the front and rear?

 

Slighty stiffer in the front is correct, in the rear they are a lot SOFTER then oem.

Tein H-tech G35 coupe & sedan(fronts are progressive, rears are linear)
324/260
Stiffer then oem by F+ 5% R-22%
Transfers +27% roll stiffness to front

But, based on what your after I think they would be your best choice. You can make things better by also chucking the oem shocks and replacing them with Tokico D-spec shocks, they have much superior valving, not just in a performance sense, but in a ride and drive quality sense.

 

I have Specialty Products rear arms on my G35 coupe. In my opinion they are necessary on a stock Z or G35 if you want to increase the life of the tires. When you decrease the negative camber you do decrease the cars ability to pull high speeds on a skid pad or at the track. I am a former SCCA driver and understand the result of decreasing the camber to "less" than factory specs. However, if you run 1/2 to 1 degree negative you will still have great handling and longer tire life. You do not need camber arms to keep the rear camber within factory specs using the H-Tech springs. Speciality Products is at specprod.com. I purchased mine from iapdirect.com. I talked with Speciality Products yesterday and they said they will have front arms this spring.

 

Correction...I talked with Speciality Products again and talked with the R&D department and was told the front arms will not be ready this spring and they are not sure when they will be available. Darn!
