My previous setup: 2004 G35 coupe with Tein 350z H-Tech springs and Tokico Spec-D struts. SPC front camber kit, rear toe bolts and rear camber arms. Initially the car was lowered 3/4" up front and only 1/4" rear. I performed the rear spring mount mod to get 3/4" lowering in the rear. This setup handled great but absolutely sucked from a ride quality standpoint. The front was OK but the rear would bottom out and rebound excessively on rough roads which we have a lot of. Increasing the dampening helped to control the excessive rebound but that would stiffen the ride excessively from a compression standpoint. I may be getting old but I hated the bumpy ride. My modded Evo rode better. My G is a daily driver and NOT a track car so started looking for something that rode better. I have previous experience with Swift springs (Evo) and the spring improved both handling and ride over stock. So I debated getting either the G35 or 350Z Swift springs. Ultimately I decided to go with spring meant for my car rather than the Z.

Despite the lack of reviews on this site for the G35 Swift springs, I went ahead and bought them. Some say the lower than stock spring rates are undesirable. I disagree. I think the Swift engineers know what they are doing. The springs are awesome. Combined with the Tokico struts, they handle nearly as well as the stiffer Tein springs but the ride quality is even better than stock despite the lowered ride. I will measure the exact lowering once the springs settle in the stock rubber mounts. I also installed unmodded rear spring mounts.

Nice, keep us updated on the springs, cuz i heard alot of good reviews for them from my buddies with evo's also

thanks for the review.... Swift is one of the leaders in the springs market, so it's no surprise really.

I do know a lot of people really still have no idea what Swift is and the work they put in their products, and that's a shame.

I had a set of Swift springs on my other coilovers, just a precision instrument straight up.

im on swift 350z springs....best spring set up ive had on any of my cars

Thanks for the review. This is good to know. Right now I'm on stock springs with the D-specs and I really like the setup - good ride but much improved damping for better handling. I would like a lower stance, but I have been afraid to lower due to my steep driveway and local potholes. It's encouraging that Swift has gone with a softer spring and you've dialed in higher damping rate and you're pleased - I think this is the approach that BMW takes on its cars as well, though I'm not 100% sure.

I measured my ride height today. The Swift advertised drop is accurate. 1" drop in front and 0.6" in the rear on unmodded rear spring mounts. I'm debating modding the rear spring mount a little but I really like how the car rides now. However, I'm sure Swift intentionally engineered a rake in the drop for handling and rotation.

Was her 04 with the OEM stock sport suspension in the beginning, since you mention Swift handles better than stock.

I'm looking at them myself.

There was no "Sport" suspension in 03-04. In 03-04 there was a Performance package with 18" wheels, Michelin Pilots, and rear LSD.

i have 350z r spec swift springs on my car. the ride is more comfortable than stock and in love with these springs and love the drop!

Thanks for the review, my buddy is debating swift vs eibach. Very helpful!

So far I have firsthand experience with Swift springs on 3 cars: 2004 G35, 2005 Evo, and 2011 STi. In all three vehicles, I can sum up Swift springs as maintaining or improving ride quality while significantly improving handling. Swift does a great job matching their springs to stock dampeners.

I have Swift on the front of my Buddy Club coilovers. Original springs were teeth-rattling 14kg/mm....Swifts 12kg/mm made ride just right. They are also quite lighter in weight.

I am debating the swift springs for my 05 G35 sedan. Planning on getting tokico hp struts and like the swift but think i want a little more of a drop that 1.0-F and .6-R. If i get the coupe springs, can i expect another .5 inch drop?

Thanks

Yes and you're welcome.

Thanks for the info! Is anyone running the swift coupe springs on a sedan? Do you like the ride quality?
