He wants to raise his rear height... by what I'm guessing is a half-inch. I would, too, if I could do it for free, and my my rear Vossens wouldn't poke with the loss of neg camber.

Modding the car is all about compromise, and I suppose some people just really, really hate compromise.

There was quite a bit of at-idle vibration after the install. So I removed the heavy rubber damper nubs that were attached to the mid-pipes, and the vibration all but went away (mostly). You don't have that option, because you don't have the OEM cat-back anymore, so IDK what to say, except maybe to put this cross-member back on, like we're talking about.

Have to come up with some creative way to weld bolts with bushings to match up with the original holes on the ends. Hmm. Anyway, here it is:

I too was looking into welding on the tabs so that I can re-attach the OEM brace that supports the Cats and Y-pipe. I even went as far as to cut the tabs off of my OEM Cats. Just have not had the time (or welder) to do it. LOL Maybe this could be my excuse to buy a Lincoln or Miller "buzz box".

I was really close to picking up a set but since I didn't really hear much about them on here or on the Facebook pages I decided to go with RSR when the time comes.
Yeah I've heard good and bad about the rebuild time. I just really wanted the EDFC, surprised other companies haven't done it.

Just throwing out ideas, but is there any way to put a spacer or larger isolator on the rear springs?

As a matter of fact there is, and it's been done by quite a few over on 35driver

No hiss that I know of...

Not at neutral when I was on RHFC with stock catback, and non with RHFC with ARK.

Lubed up my rear sway bar bushings with some green synthetic waterproof grease I picked up at Auto Zone. No more squeak

Also noticed one of the exhaust mounts that bolts to a stud was missing a bolt. Fortunately I had a something to fit in my collection-of-miscellaneous-nuts-and bolts-collection. And that, boys and girls, is why it is probably a good idea to double check all the hardware a few hundred miles after installing a cat-back

While I was at it, I dialed in another turn, front and rear, for the Konis. This takes me to 3 sweeps from full soft for the front and rear. Surprisingly, the PSS seem to have softer sidewalls than the Potenza S04s, so I wanted to stiffen things up

Bought set of wheels with 245/45/19 tires, still have decent tread so I'd like to try to get a year or two out of them (drive <5000mi/yr). Calc says 3.6% increase in overall dia. which will throw off speedometer (slow) & odometer (short) readings. Anything else I should be concerned about??

And looks are subjective but not entirely hating a little extra meat around the wheel

I think OEM size is 245/40/R19, either way shouldn't be a huge deal. Are they staggered?

Connor, how do you like that non-resonated X-pipe?

Lego, how did you adjust the rears without dropping the struts? I REALLY, REALLY want to stiffen up the rears. Since it's been some time since I've done mine, turning the screw on the top of the fronts all the way to the left is full soft, correct? Thank you in advance, sir!

Ok thanks.

Wheels are staggered, tires are same all around (guess for an AWD setup)

Only other issue will be learning to drive with touring a/s tires vs. the OEM summer tires

I had made sure to mount the rears with the window facing out. Jacked up each side individually, took off the wheel, and squeezed my hand up in with an allen wrench and got them turned.

It would have probably been easier to drop the shocks. They are only held in by 3 bolts, and the two at the top are like 10mm. If I do it again, I'll just drop them.

The adjustment **** should have the firm direction on it.
