Quick update after participating in several more autocross events. My combination of swift springs and OEM sport struts is still performing very well. I have zero regrets. This is MUCH better than the stock setup in my opinion.

Swift Spec-R

Hey All, No question, the swift springs greatly improve the handling, however, I was just getting at the drop as it was just simply too low (pics included). I've basically determined that it was a total crappy install, as the bump stops were destroyed (supposedly installed new ones, BS!!!) and my strut mounts were totally cracked too (post install).

I switched over to Dinan Springs, and I tell you, it doesn't handle nearly as tight as with the Swift Springs, which really is quite disappointing. I am heading up to LA tomorrow, adn will be crushing Angeles National Forest, and several hundred miles of mountain roads, to really give it a good test. Dinan Springs are definitely a step above stock, but the Swifts really were tight, but the ride quality was awful, and not being able to go over speed bumpts or driveways, was really quite ridiculous (again, most likely a result of the shoddy install by HP Autowerks).

Just check out the pics, and you can see just how ridiculous the drop was...

Regardless:

FS Swift Spec-R Springs, only 1,500 miles on them!!!! $300!! LOL!

Here are some pics too.

I’ve had the Swift / Koni setup in just over a week now, the “ride” feels perfect and handles amazing!
My driver’s side rear is low, just like your photo (tire tucked into fender), the passenger side rear is perfect, just like the fronts (can just see the top of the tire). Going for an alignment next week, hopefully this will correct the difference. If it doesn’t correct the height difference, I may need to look to Swift for some replacement rear springs.

I contacted Swift and had the rear springs replaced. The ride and handling is perfect considering the amount of drop. The Koni yellows work really well with the Swift springs dialed in around 60% of stiffness. I'm currently plowing snow here in Toronto, but no real issues with the suspension.

My gap is gone, rear is just slightly tucked. Koni yellows seem to be holding up well (no bouncing, nice and firm). Trying to avoid potholes at all costs, more or less I've been dodging the chunks of ice buildup from other cars on the road for the last 2 months, spring time can't come soon enough for me now.

I realize im digging up an old thread here, but I am currently debating getting a set of Swift Springs with Koni Yellows and I can't find a whole lot of information. I'm a bit worried that the swifts will be too low/rub with my current setup (18x9 ET30 235/40/18 front and 18x9.5 ET35 265/35/18 rear).

Any long term reviews on these springs? I really like the stiffer rate, but as I said, I just dont want to rub or scrape on everything.
