H&R Lowering Springs?

CBRich · 01-04-2010, 04:34 PM

In one of the threads here recently I thought I saw mention of H&R springs being in development. At their website they show an application of springs for the 370 but I can't find any other information about them.

Does anybody have any info on these at all?

Take that as a no.

Not heard anything about them yet.

I saw that as well. I am interested in them as well because of the drop. I can't seem to find anything on the spring rates though. I guess I will just keep looking.

I would be very surprised if you find anything on the spring rates. They dont give it out and I could not get anyone to give me an answer as well. Not even the reps at H&R would respond to that question.

When they made the 350Z versions...same thing. Other users could only guess on the rates based on other spring comparisons.

Though if they really drop the car 1.3 inches...its going to be pretty low. But you will remove pretty much all of the wheel gap. The Tanabe's at .8 ish are pretty low already.

Goodluck though on finding the rates. If you do somehow though...post it up. The look would be pretty nice. Looks wise...comparable to most on coilovers since the average drop seems to be about 1.2-1.4.

Agreed, it is difficult to get some spring rates on H&R stuff.

However, I hope they're stiff!
They are available for sale as well, and I may stock a few sets..

H&R Springs for the G37 were the springs that gave the biggest drop. I assume it will be the same for the 370z.

I currently have the 18's on mine and the wheel gap is 1.75" in the front and 1.5" in the back. I plan on putting 19's on soon. You say the Tanabe's are already low but what bothers me about them is that they drop an inch in the rear. Why would anyone want .95" of gap in the front and .5" in the rear. Shouldn't it be the other way around?

You would think...but it is not that bad actually. I think that the assumption is that when you are racing or autocrossing...the weight shifts from the rear to the front, when braking hard before a turn. Too low of a drop in the front and you will be dragging something down there. Remember this is only springs so we dont have dampening rates on the shocks to control any weight shifts, compression, or rebound.

If you are looking for a level/even lowered look, then you might want to use coilovers versus a spring only drop. That way you will be able to fine tune things a bit easier.

Using the Tanabe GF210 springs, with the 285/35 in the rear...I cant get even a finger in there straight. The front is barely 2 fingers of a gap. Maybe 1.5 or so assuming you stay with a 245/40 front tire. Though...I am on 19's.

Hope this helps a little.
