Installation of the Agency coilovers took about 3 hours. Nothing out of the ordinary for the installation, everything was straight-forward and there were no fitment problems or oddness with the parts.

I spoke with Fab’s techs after the install and asked them their opinion of the Agency build quality and ease of installation vs. PSS9, HR, etc.
They both felt the build quality looked quite good and installation was no different than any others.
They did note concern of the rear dog bone ball joints and felt these parts may wear out rather soon, but that they are also easy to replace.
Also noted was a lack of suggested setting parameters, so they left the damping at the setting as-shipped from the factory and only set the ride height (5/8″” drop front / rear).

I had concern that the 15mm spacers may be too much for the rear but Fab assured me that with OEM wheel offsets it is totally fine. He also added that you can go up to 20mm safely. After looking at the outcome I would say he is right- I still have room if I want to space it a bit more!

So, installation was finished, ride height checked, and an initial alignment set (we will do the full alignment next week after the coilovers settle in)-

Fab jumped in the car himself for the maiden test drive (looks like Fab test drives all customer cars personally, I like that!).

He was actually gone for quite a bit, then rolled up confidently with a smile.
I asked him “what do you think… good / bad / iffy?”
He said they felt great- He was surprised since they had not adjusted the damping from the factory settings, but he felt that it was ‘just right’ and wanted to leave it that way for this next week of driving / break-in.

He told me to jump in and check it out- So, off I went- Straight to the 405 North and hit a few crummy streets on the way.
Here is what I noted, my comparison is vs. the stock OEM suspension.

-Bumpy streets at low / medium speeds. Huge improvement. I thought these coilovers would feel more harsh, but they actually muted the sharp bumps and had no ‘jarring’ like the OEM setup had. Very pleased!

-Freeway at 65, crummy pavement sections. Much improvement, same notes as above. No “cheap suspension” bounce, firm and smooth. Very pleased!

-Freeway at 85mph to 115mph. Again, high marks. No more ‘porpoise’ at higher speeds and nice and firm withought being jumpy. I feel more confident now pushing the car faster.

-Big dips. No bottoming out, it is a firm but soft ending to the suspension travel and no hard jar like the OEM suspension. Very pleased.

– Cornering. Cornering was limited to freeway sweepers, it felt much firmer and less body roll. My alignment is slightly off so will reserve more serious cornering tests for post-alignment. I think they will do quite well though.

-AutoX / Track. Well, I don’t know yet. I don’t autoX and I have not made time to hit any of the local tracks.
My only concern after today’s driving is these might be a bit soft for serious track use, much like the PSS9 or HR (non clubsport) setups. I have no idea what the damping is currently set at so I will crank it up to full firm this week and see how that feels. but, these to have the adjustable camber plates in front so that may be of nice benefit to the more track-minded crowd.

Overall, after a few hours of town and freeway driving on all sorts of roads, I have to give these Agency’s two big thumbs up. The overall feeling is firmness without being harsh or bumpy. They feel solid on the car. I think if priced right they might be a good purchase consideration. If they continue to ride the way they ride today, I will be pleased to own them.
