Anyone else think the RS looks like the rear sits a bit too high?

What is the experience on STs with moderate lowerering - maybe 10-15mm at the rear.

Are these cars sensitive in suspension geometry or do they lack travel to ward me off an esotheric trim adjustment of the rear springs?

Please leave the geometry alone. For the sake of handeling, CA joint life and aero considerations it was all designed a specific way.

It won't be long before some ja changes the camber to "stance" the car. I can only shake my head

One has already been put onto coilovers. I'm not a fan myself and will be leaving the suspension stock as well.

When I first ordered my car and was looking at forums to join, I came across one whose most popular thread was a Photoshop of an RS that had been lowered and stanced. Everyone was circle-jerking around the picture, so I just closed that tab and joined this forum. Thanks, I guess, for directing me here?

I will be leaving this one as designed. I changed all the suspension on my current car, and while it handles awesome, I hate the day to day ride.

Since the car comes with dual mode dampers, I might put a set of springs that have a very slight drop, but that would be all. The car is fairly low as it is, with some aero bits and the RDU out back, don't want to scrape anything off. That being said, I would prolly fit some sort of metal skid plates to the front and rear. I have had bad experiences with large rocks while returning from snowboarding.

Nope. It looks balanced to me. But then, I do prefer a bit of rake over the stanced look...

10-15mm is around half an inch. For lowering a car that is pretty minor. A person or some cargo can do more to lower a car.

As everyone appears to be saying, leaving stock is probably the better idea. Especially if you include the dual mode struts in the equation.

My thinking is I will leave it stock for a year or two. Then depending on how I feel about the ride quality, look at the Ford Racing/Ford Performance springs. For the Focus ST they lower the car between 1/3-2/3 of an inch. This does assume Ford Racing/Ford Performance will make a set of springs for the RS.

Nope....sits perfectly. Leaving mine bone stock! The first time I see someone who #hellaflush #stancenation #parkinglotposers their RS I'm going to visibly shake my head at them ;)

Wasn't quite suggesting Liberty Walk, stanced, dropped or really even actually lowering here.

All standard Foci have say a 3 deg forward rake. It, the RS, doesn't look like it 'squats' in the tradition of many, many fast & cool cars. None the least its Gr4 Escort forebares.

I get all the tech issues about aero angle of attack, suspension geometry, bump travel, CV angles.

For example: an STI has rear suspension geometry issues and not really sufficient bump travel - when lowered more than a modest 10-15mm (1/2") you get into fast changing toe and camber changes causing significant handling irregularities, mostly causing poor loaded cornering grip on the outside rear wheel. When compounded by short bump travel they are prone to snap oversteer when driven hard on bumpy roads. Not so good, especially for a car that is inclined to understeer on corner entry, in part to the boxer engine hanging out there on its transaxle way past the front axle. Understeer in, chase snap oversteer out.

The aero is, for intents & purposes, academic for my use patterns. I am obliged to have roof bars for bicycles permanently fitted. I don't expect to track the car except for perhaps to get to know how to drive & over drive it - If I want to chase hundredth of a second on a track it won't be done in my daily drive. My VW Tiguan with a dirt bike in tow is stable enough at over the imperial Ton - While 165 mph is a cool number, in Australia they put you in the back of a police car well before then.

So, does anyone have experience with Foci suspension (pertinently - the rear) and the geometry constraints when subtly lowered?
From the pictures of the underside of the RS can a familiar commentator offer if it shares the basic suspension structure (with RDU adaptations)?
Can an ST tolerate some lowering without compromising either geometry or travel (more than the obvious bump reduction) without reducing grip and stability.

Springs are cheap & easy to swap. I'll probably have a pair made - assuming all comes off.

I can't help but laugh a bit at the suggestions of negative aero affects in this thread. Unless you have the sensitivty of pro racer to vehicle set up changes and are planning on cornering at 120+ mph on a regular basis, do you truly think you'd notice the difference brought about by a small change in ride height? Likely not.

Personally I think a slight drop of 1/2-3/4 inch all round (I like the functional look of the rake) and some 18 inch wheels with larger sidewall would really set the looks of the RS alight.

^ I like this so much that I unlike it. Just to like it again

My ST is lowered with steeda springs and have Bilstein B8 dampers. It didn't upset the balance of the car at all. I also added a Steeda rear sway bar and the car still behaves like it should and only enhanced the character of the car.

If I decide to lower my RS I'll go with whatever Mountune comes out with.

Here's a video of my car with it's current setup:

Much more useful than, say, upsetting my aero balance....

Even with the (assumed stiffer) rear sway bar 'It', 'She', your Focus, looks a bit front grip limited?

Care to comment on your wheel / tyre package?

Also - the B8's. I fitted some Billy B6s' to the Tiguan a couple of months back (similar to B8 but for long travel standard ride height, rather than B8 to suit lowered short springs). Night & Day after the flogged out OEM dampers. A bit knobbly but not as much as I feared - this is my wife's car 6 days/week - but how they gobble up bigger holes & bumps, especially g-outs and the loose surface corrugation grip improvement is astounding. Highly recommend the Bilstein lineup. No surprise really. I had some in a little Mitsubishi Colt (Gallant here) rally car when I was a naïve, pimply lad & thought they were pretty good then too.

Did your handling package evolve or all go on in one hit?
How do you rate your B8's? Interesting because I may be able to relate to the B6's somewhat.

Cheers.

Hey Pete!

In that video I'm on 18x9 Team Dynamics with 245/40 Dunlop Direzzas. With that setup the car is actually very balanced for a fwd car, and at the limit (as seen in turn 4) the rear end likes to step out.

To give you an idea of how good the front end is and the balance of the car here's the same track with the same setup:


I did switch tires this past weekend, changed to Michelin Cup 2s. Same tire that's optional on the RS, only I went with the same size as my Dunlops (245/40). Note that these tires run big! They look like 255/45s compared to the Dunlops. With that setup on a stickier track surface at the wonderful Atlanta Motorsports Park, it made the car extremely neutral. The Cup 2s are an amazing tire, loads of grip and they're quiet and comfy for a track oriented tire.

Here's video of that:


Initially I just did springs and the sway bar. Quickly found the OEM dampers weren't up for the task, so I shortly after made the switch to the B8s. The setup is a little bouncy at lower speeds, but once you're going it's as comfy as the car was stock. Added a level of refinement to the handling and ride, made the car more progressive at the limit. In conclusion I really really like them!

Yes! Will rotate.

Smooth hands (no, not getting all metro). Did you see Tiff's jiggly-wiggle wheel work in Chris Harris' 918/LaFoza/P1 piece? He gets it done but busy hands is to understate...

lol! Oh yeah! That's one of my favorite videos. Excited to see the ex-Top Gear guys play with them on the new Amazon show.

Speaking of busy hands, this requires lots of jiggly-wiggle wheel work:
