Hello,

So I can purchase some d2 coils used for a good price. The guy selling them also has some swift springs available. He never ran the d2's with the swift, so I can't ask him how the ride is. But I wanted to know if it was worth the extra money to run the d2's with the swifts. I know d2's are taiwanese crap compared to bilstein/kw, but would pairing them with swifts make them a bit better than by itself?? Any credible feedback appreciated, thanks

And a follow up question. Would tokico struts with swift springs perform/handle better than the d2's? I am looking mainly for comfort, won't really be slamming my ride even with coils.

Are we talking about Swift specific rate springs like i run on my coilovers or, 350Z specific Swift lowering springs?

If they're Swift springs that are in sizing/specs for coilovers, they will be an improvement over what they come with, however the dampers are not the best from all the info available online. Swift makes great springs, whereas many coilovers just come with generic ones where the spring rate kind of gets wacky once they start compressing.

^^Just the person I hoped would chime in. Yes, swifts for coilovers, not their normal lowering springs. What coils are you using them on? Would they make a big difference over just d2 springs?

A spring is a spring (talking about specific rate)

A china 8k spring is still an 8k spring, yes the tolerances are not as good as a swift but most people will never notice the difference.

8k is 448 pounds, a pair of china springs may have a 450 pound and a 440 pound spring. Then over the course of time the spring may change a bit more. Unless your a serious track junky, no need. Besides the crappy D2 dampers will hold you back anyhow.

I would take china springs on quality dampers any day over a set of china dampers with quality springs.

Here's the million dollar question. For an extra 200, would you get the swifts and replace the china springs? I heard so many good things about swift springs so I was expecting them to help the coils perform a little better. A friend of mine told me his stance with swifts are silky smooth on the road.

What rates , OEM or true coilovers position

VMRWheels

Just save the extra money and stick with what they come with. Yeah, Swift makes some of the best stuff but you won't notice a big difference in real world driving.

true coilover position. Spring rates I believe were 12k and 8k front/rear

8k in a true coilover for the rear is too much...

terrasmak

iTrader: (8)

I would not want 8k rear as a true coilovers without a 16k up front

(ZzzzzZ)

iTrader: (1)

wow really? What should the rear be on a true coilover setup? The d2 spring rates are 10k front and 7 k rear

terrasmak

I run a 12k front and 5k rear for a well balanced setup. Very similer wheel rates to Nismo T2 springs that are 12k front and rear in OEM location

For equivalent wheel rates on my car it would something like 16k/~7.5k. This is on a race tire equipped car.

Just went for a ride in my friends z thats running d2 coils, true coilover setup. Ive never riden in a ride with coilovers, just stock suspension, so I'm not entirely sure how coils are supposed to feel. But I didnt like the ride. The car would be smooth and drive straight/level to the ground if the road was flat, but if the road was even remotely bumpy, uneven, or had some holes, the car would kinda sway left to right on turns and the front would rock up and down a little. I was expecting the car to stay planted and drive perfectly level to the ground. Is that an unreasonable expectation from coils?

D2 coilovers are known to be stiff. I would suggest to save up more and get some KW coilovers.

The D2 coils are **** because of the adjustments, more than actual dampening. The adjustment range is not fixed, it's exponential because the adjusters for the foot valve are cheap and shitty.

Just as an FYI, Swift does not use conventional spring steel; they have a proprietary alloy supplied to them by their parent company. The proprietary alloy allows higher spring rates to be used relative to control without the normal jarring feel that higher rates afford. Because of this, when getting Swift's springs, it's generally recommended to order higher rates than an equivalent from another manufacturer.

VMRWheels

D2s are documented to be somewhat stiff/bouncy to people.

From my understanding, Swift and companies like Hyperco for instance feel a bit smoother than typical springs of the same rate would.

If you're not looking to slam a car beyond where all of this matters, I wouldn't recommend D2's. And this is coming from someone WITH D2's on his ride now. I love mine for the price, but I'm SLAMMED. I bought them to SLAM my car. While the car has seem some moderate drift time, I still wouldn't really recommend these if you're looking for a comparible track setup. I recommend D2's if you're looking to slam on a budget. My situation was I had issues with my BC's and wanted something quick to toss on. BOOM. D2 saves the day. And again, I'm happy with mine. But the only time I honestly recomend these is for slamming on a budget. REAL TALK. And I'm less than 2" off the ground for reference. At that height, suspension geometry is so far outta whack and at that height, you're gonna feel the road regardless...especially with a thinner sidewall. So that's why I'm saying the stuff you've mentioned doesn't really effect me cuz CLEARLY I'm doing form>function
