According to Mike Kojima, you shouldn't really drop a b15 more than 1 inch. Anything lower you start to mess with the camber curve and roll center. I think he mentioned that you should ideally relocate the lower control arm ball joint if you want to go any lower.

Really up to you, choose your preference on how you like the ride. Start with the lowest setting and work your way up.

i agree. tried a lot of different heights, no reason to go very low.

well guys ive been driving for about 3-4 months now on my koni yellow, vogtland combo. the ride is amazinf as well as handling. and the drop is right about perfect. my fornt drop hieght on stock tire size was 1.7 inches, my rar drop hieght was 1.6 the car has a nice rake to it now. i am currently running my rear koni's at 3/4 stiff and the fornts maxed out stiff. paired with nismo stabilzers front and rear, rear one set at roughly 3/4 stiff, and a nismo lower tie bar as well as a stiffer megan race front upper strut brace. i would reocmend this setup to anyone in the budget department as its not costly and is worth every penny.

i havent hit the bump stops yet, and have no weird rattles or vibrations. entering parking lots is a bit of a challenge at times but overall 5 stars for this combo

Thanks....I think the shop that did the install has me a bit too low (1 finger all the way around) will have them raise it up at least a 1/2"

Damn I wish I would of seen this thread before I purchased the Sprint springs a few years ago. I'm going to change them for the Eibach sportline springs soon. Anybody have any opinions?

I just got off of the phone with Tein USA, (562-861-9161) and was told that the spring rates for the S-Tech are actually 170F/270R as listed on this page: http://www.tein.com/ti/p02.html and not the 151/196 listed on http://www.tein.com/nissan.html

Just an FYI. I cannot confirm beyond talking to Tein, but that is what I was told...

Thanks for getting that information from Tein, I went ahead and updated the first post. Why Tein would have two different spring rates for the same product on their website is beyond me, if they are smart they will correct the information.

While this is indeed a better spring rate for the S-tech, you get the same drop (1.3"F/1.1"R) but much higher rates with the Tanabe GF210 at 207F/314R. Since you must have higher rates to compensate for less wheel travel that comes with any ride height drop, I would pick the Tanabe GF210 over the Tein S-tech.

When I asked, the rep told me that Tein Japan posts the website info. He did say that that was a concern, and that people who actually pay attention to spring rates (as opposed to only drop height) will be better served if they are more consistent. In actuallity, the rates are 171/268 (I think), but he said to use the 170/270 numbers on the first link. He said that he would send a formal inquiry, and seemed genuinely concerned at the contradiction.

I agree with you on the Tanube being preferred rates, but Teins are a much less expensive spring, which will mean that as a temporary setup (meaning, transitional prior to a more permanent set-up), I think that the Teins will be popular.

It makes sense that the rates are actually higher, or we would hear a LOT more people on the TeinS/stock struts setup blowing struts, since a lot of new owners seem to use them. As it stands, the lack of complaints led me to do more research on the actual rates.

Even if this thread is just about spring rates I think this link should be added as best bang for the buck in Sentra suspension.
It would be nice to see the full stock travel listed as well so the benefit is obvious

Yes it will bolt on to the 1.8. Dealerships are freakin idiots, my dealership said the same thing but all b15 suspension parts are interchangeable.
