Here is the before video on the busted up road I was talking about. stock suspension with SPC camber bolts only. RS3 tires.

After I installed the Swift springs, still with SPC bolts and Asymmetric 2's

Not sure if you can see the front pogoing after some of the bumps and potholes on the second video.

Yes it rebounds to quickly with these springs, but it's not horrible. The rears are pretty much on point. That is why I think the 3k or 3.3k front spring of the FR-s spec and hotchkis would be closer to ideal.

Believe it or not my fastest time on that road was with stock suspension and tires.

more pics! =)

Just confirms that I need to wait for bilsteins, go cut koni or get more of what i already got, which I was trying to avoid...

Thanks so much for feedback

Passenger Side Front:

Tire marks on front coils:

Front clearance with tire. My index finger feeler gauge was pretty accurate. abt 3-4mm clearance at full droop.

Nemo camber:

Driver side rear:

I'm hoping a 5mm spacer will let me add some more camber using a second set of camber bolts on the strut bottoms while eliminating the tire contact with the coils. May have to go 8mm spacer...

Did the spring come like that? Also, on the lower spring perch are your springs seated like what you see in my photo?

SPC camber bolts and Swift BRZ springs.

the spc camber bolts and the 1" drop is getting me about 1.5 degrees of neg camber, more or less.

Just a little update on my suspension with the Swift springs installed. Initially after installation the rear end felt very good with the factory dampers offering enough damping for these up-rated springs. Now, while I'm still pretty satisfied with the ride and performance, I feel the rear damper's compression damping to be a little bit lacking for the springs. I'm not sure if it's the oil in the factory dampers breaking down in viscosity or if I just hadn't noticed before, but the rear seems to have softened a bit. Not to the point of bottoming, but compliant with a little boat-like action over some bumps.

I suppose you really can't ask for too much with just lowering springs. I'm sure when they are coupled with heavier duty dampers they will be that much better.

Here's a recent test 'lap' I did with stock wheels and tires after adding some more negative camber out front. http://s174.photobucket.com/user/sol...43611.mp4.html

Did you cut the bumpstop during installation? I haven't driven around enough to have a proper impression of the springs but so far been pretty happy with them.

Yes I cut the bumpstops.
