Coilover Suspension

[Schu]

In the front my tires are a few mm away from the strut body. Spring perch is higher than the tires.

we were talking about coil overs... not OEM struts.

Here is Dusold Design's thread with 18x11 wheels front and rear: http://www.mustang6g.com/forums/showthread.php?t=12272&page=6

that is perfect... I love Azenis, until they get greasy

Depending on design the coilover spring perch may still be higher than the tire. In this case it better be or my 285 tires will not fit if the spring is lower on the street body.

So same issue. The strut body is the clearance limitation in the front.

I have a total nob question for you guy's, go easy on me. If we get true coilovers in the rear, what happens with that huge cast aluminum piece attahed to the sub-frame carrier, that the current rear spring is perched in?

Does the spring stay to suppliment, or it just sits empty or what?

this is the exact reason I have never run them...especially on this heavy ass mustang lol ya might make it through half a lap, at least on anything thinner than what Dusold is running

Yeah, I'm going to probably buy some wheels from them with the correct offset for the front. This pic makes it look like the front poke's out a little, so wonder if the wheel would catch if they lowered it a couple inch's

Great time!

On great wheels.

front poke doesn't bother me... poke at all doesn't bother me.

has Offset been discussed yet or is it still secret?

1) It is unlikely that there will be any "true" coilovers for the rear except maybe for "almost no rules" full race cars with roll cages that also provide very strong mounting locations for coilovers. From looking at the factory service manual and my car in detail there probably isn't enough strength where the top of the shocks mount to also handle the load of the springs and the shocks. The top of the factory spring is supported by the "frame" of the car which is very strong. Also, as various folks have stated in several of the many coilover threads, there really isn't enough shock travel available for shocks to work properly in the factory spring location. Shocks need to move a reasonable distance to work properly.

2) The huge cast aluminum piece where the bottom of the spring sits is the lower control arm of the rear suspension. That part isn't going away. Good explanation of both the front and rear suspensions here: http://www.edmunds.com/ford/mustang...15-ford-mustang-gt-suspension-walkaround.html

Hope this helps.

you spoke to soon ......These work perfectly fine in the production car without any problems (lol)

Interesting. I would love to see the structural explanation. Any pictures that show the actual mounting brackets for the rears? The pics just show normal spherical bearings.

Edit: JRI dampers are certainly "credible"!!!!

Ridetech will also have a true coilover in the rear. Currently in testing.

Spoke to KW today.

Front and rear springs are progressive on front and rear.

Let me know if you guys are interested.

The springs in the PDF aren't progressive. The rears have a keeper spring it collapses completely when the car is sitting. So the spring rate on those thin springs are only strong enough to hold the springs from coming loose in their perches. I had KWs on my 2010 they weren't progressive and I measured the spring rates if I remember correctly they were 350 front 250 rear that has no bearing on the S550 of course completely different geometry on the rear.
