Def at least give the back a shot if you have the tools. The shop time to do the fronts vs the backs isn't that different since they have stronger tools, so you'll be saving almost half the money and installing the easy half yourself.

Just had mine installed -- after a few days of settling, based on OEM height I'm currently measuring a drop of about an inch all the way around.

To be more precise - OEM height on the Sport Rays: F= 27.87"; R=27.99"; on Swift Spec R: F & R (so far) both = 26.94"

Pics in gallery ("Back in Black!").

:tup:

Jordo, grats ! Give it few more miles and see them drop another .25 ..IIR. Note: most have seen the passenger rear to be a tad higher even after all four corners settle. No explanation as to why...prob because most weight is always on drivers side..dunno, makes sense thou.

Enjoy them Swifts !

Curtis!!!!

Hello.

BTW: I put two calls each into Pierre and Chad the week before last and neither returned my messages. :icon14:

^ Pm'd you.

You are the man. Thanks.

Weird. The passenger rear is actually lower than all the other corners for me.

Just to add to the Swift height database, this is after almost 9K miles:

26.55" driver side front
26.50" passenger side front

26.60" driver side rear
26.35" passenger side rear

For anyone about to install or thinking about installing springs:

Remember to torque down all the pivot point bolts with the suspension under load!

On the front, use a hydraulic jack under the brake disc to raise it up to where it would be while driving, then tighten bolts. The distance between fender and center of wheel bearing is about 14" under normal load with these springs fyi.

I wish I did this the first time around :ugh2:

Hopefully getting my springs today, just need to wait for my tires/wheels to arrive. Waiting sucks!

Another day and the car is even lower?!

Current measurements:

F = 26.69"
R = 26.81"

Total drop from OEM now:

F = 1.18" drop (just shy of advertised 1.2")
R = 1.18" drop (over advertised 1"!)

Car looks and feels really, really good (note: Koni yellow shocks with the springs) -- about 1 finger of fender gap between tire and wheel arch.

I'll share some fresh pics later in the week, or whenever I see no further evidence of additional dropping.

What's your settings for the shocks??

I can't wait to get mine on... waiting really sucks ugh.

I wonder if it's normal to have variation like that. Even if it's not a lot.

I actually attempted to find a shop with a shock dyno in my area so that I'd have a very clear idea what effect changing the setting would have -- and it was a failure (although they seemed to think after playing with each shock that the dial only adjusted rebound rather than compression or both).

The two shops in my area that can do it are set up specifically for Penskes, and had no way to mount the Koni to their dyno :shakes head:

Luckily I know of a very good shop in my area that preps track cars routinely, and has experience with Konis, so I do not know the exact settings, but they told me they were set to "medium firm" (which is kind of meaningless)...

When I go back for an alignment tweak in early December (when I have time and after the springs have completely finished settling), I'll see if I can get more precise info to share.

Sounds good bud. My swifts settled already.

Hi guys,
I just installed my Swift 3 days ago and I havent had my alignment done yet. I will do it tmr. However, My steering wheel were shaking pretty bad when I drove back home these days. Is it a normal thing that happen when We just installed our Spring or its because of somehting else. My steering wheel was fine after installing the Swift plus the front spacers. I think its either the Spacers or the Spring. I am just worried but will get alignment done by tmr. Hope u guys can help! Thanks

Spacers

:iagree:

Definitely spacers, even some of our customers with the higher quality H&R spacers have this problem when using them on the front!

Never go cheap on wheel spacers! I would only buy H&R

:iagree:

It could also be the alignment. Did you include rear camber arms? If it feels really squirrelly, your toe settings may be off.

I'm still scared to get these springs, I feel like I will ruin my f1 exhaust and I already scrape that black under spoiler guard.

I just don't want the saggy spring too low look

Good, you wont get this with the Swifts:tup:

Swifts are about the best bang for your buck mod you can do to the 370. They increase the handling a ton and give it a much needed drop. Get $600 bucks together, buy some Swifts, a set of sway bars and itll handle 7834989 times better.

:iagree:

thanks, ya i already got the PSS that helped my handling tremendously thanks the mronzedge praise. Swift springs are for sure next. Some questions`

-will i be ok with 20mm spacers all around?
-Also i will need an alignment for sure right?
-What about camber toe stuff! If i dont really care about tire wear does it matter or does it help your handling.

I have the FI exhaust and Swift and have only scraped one time in over 2 years. Took a speed bump on angle and touched one can, its fine barely touched it. Just take speed bumps head on and you will be fine.

spacer size will depend on what wheels u are running. if factory, then 20's all around should be ok. swift springs definately not give u a crappy saggy spring look. in orger to not scrape u will jsut have to be aware of potholes, and entrances. take angles, and go slow.

u will deifnately need an alignment. with swifts the front camber can remain just in spec. while the rear will be JUST outside of factory spec. not enough to make a big difference on tire wear


here's a pic of the stance of my car with jsut swifts.

as u can see, its not like they "slam" your car or anything. just give you a nice mild drop to take out some wheel gap.

also, as i'm sure many can atest too, your car will be much less twitchy under mid corner bumps with these springs.

Once dropped on Swifts how do you guys deal with the small plastic air dams that are right in front of the front wheels?

It seems these little plastic pieces scrape everything even at stock height?

I appreciate your feedback.

Im not gonna lie, mine scrape on EVERYTHING.

No worries, they are flexible and bend with every scrape.

I took mine off. They also scraped going up the rhino ramps I use. They've been sitting in my garage for 1.5 years!

I understand their purpose, but I haven't noticed any ill effects at highway speed without them.

Actually, you might say they are self clearing. Scrape them enough & they'll stop scraping ;)

Your exhaust or the plastic pieces up front?

Thanks for your reply :tiphat::tiphat:

What is their purpose?

Look up Bernoulli's principle and aircraft flight dynamics. Its the exact same idea.

Essentially, lift can be generated at high speeds by creating an area of relative high pressure under the chassis.

The chin spoiler and little air dams serve to redirect the flow somewhat to negate this effect I believe.

Plastic pieces.

Question.. I was thinking about getting the HR springs because it seemed like they had more of a drop, but I was comparting the specs to the swifts and it says that they are the same? It also seems like the swift are better performance wise. Any thoughts?

Function over fashion for me. I got the Swifts for the performance.

All depends on what you want. If it's just a drop you want, you can save a few $$$. I wanted performance not a drop, but it came with the performance so it stays ;)

Well I definatly dont mind the performance gain, the more I read this thread it seems like swifts are the way to go

is this a problem with all spacers even with a proper alignment?
