looks very nice. I'm thinking about the same spring for my coupe. please keep us posted on ride condition and your over all feel for it. please let us know also how's the allignment goes--- ( camber or not). Thanks

 

Whats the drop for the H-Tech Springs? 0.5 inch?

Which do you think is better, Eibach or Tein?

H-Tech drop is .6"/.3" and S-Tech is 1.2"/.9". The S-Techs should be very similar to the Eibachs, as far as I know there aren't many complaints about either. If you do a search you can find more info about both Eibachs and Teins - IMO you can't go wrong with either if you don't mind a progessive spring.

What do you mean by progressive spring?

The H. Tech only drops it .6/.3? Is it noticeable? It seems like I woudlnt even notice the drop in the rear. Why didnt you get the S. Tech?

Its noticable but its subtle at the same time. This is the first time I have put lowering springs on a car, and I wanted to avoid going too low for my taste. If you want a very noticable drop go for the S-Techs or Eibachs. However, if you drop it 1" or more there is a very good possibility you will have camber problems and won't get it aligned within spec, although you can probably get it close.

I am no expert on spring rates, but I believe a progressive spring has softer initial rates and increases in stiffness as the spring compresses. The stock springs are linear so the rate is fixed. Most aftermarket springs are progressive with RS*R being an exception. If you are going to track your car you might want to stick with linear springs and the RS*R's have been getting good reviews - drop is .6"/.6".

Nate, what is up with the alignment? have you had it done and what was the spec.? I'm ready to order these spring, but wanted to make sure that everything is cool before i take the plunge. thanks

<hr></blockquote> I always thought the 350z RS*R's were linear both f/r too. However, it appears we were only 1/2 correct. The following comments were made by Koji Ikeda, RS*R Director of Sales and Marketing here on 3/10/04.<blockquote><font class="small">In reply to:</font><hr>

Thanks again for all the comments. The 350Z spring is as follows:

Front Spring - Progressive Design.
Rear Spring - Linear Design.

Why the difference? RS*R spring designers have spent a considerable amount of time between different designs for the springs. When all is said and done, this design; drop, spring rate, linear vs. progressive, netted the best spring design for what RS*R lowering kits stand for.

The G35 springs are progressive for both front and rear. The engineers at RS*R have done a fantastic [job] creating two springs that compliment the specific cars very nicely.

RS*R G35 Downsprings

Drop: 1.0" front / 1.2" rear
Spring Rate: 315 front / 315 rear
MSRP $329

Remember, we have both the 350Z and G35 springs.

350z Part #: 30-N200 (down spring) 32-N200 (Ti2000)
G35 Part #: 30-N400 (down spring) 32-N400 (Ti2000)

<hr></blockquote> So, it appears that there are now two very different downspring options from RS*R for G35 coupe owners to consider! Got 4 myself, but hope this helps out the 2drs.
