Getting excited... pick her up tomorrow...





Tomorrow they finish up the rear. Subframe bushings are already in.

might be doing something else too if they have time

[CJ421]

I was just down there yesterday getting track inspection and spacers and stuff ...

That car is going to bring an instant smile to your face when you get it back.

[ashmostro]

Ha! It's a good crew ain't it?

I know dude I'm pretty pumped! Finally decent handling... Can't believe the crap BMW puts on such a capable chassis to satisfy the lemmings.

[ashmostro]

All done! Will post up reviews of various parts and services separately...

Which toe arms are those?

They've changed colours from the blue:

Aha I see that now. The OP has a psychedelic rear susp Looks good. Rear sway bar too?

[ashmostro]

Hehe yeah the colors are funny but I think it just gives it more character :-D

The sways are e93 m3 front and e92 m3 rear. Slightly more forward bias without erring too far to lose rear grip.

[BRGmatthew]

they changed the color because all of megan's track cars are pink now

[ashmostro]

How it sits now

[CJ421]

How's the car handling/riding vs. stock?

Did you tell VAC how much lower you wanted it?

[ashmostro]

After tweaking the fronts for more rebound damping, the car is pretty good right now. I haven't had a chance to really test out the handling yet since our roads are so damn boring, but the comfort is quite good - better than I expected and I was expecting a lot! There is more jounce at low speeds which makes sense since the natural frequencies have gone up 50% and 20% f/r. At speed the ride is more comfortable than before due to a calmer disposition. Over a sharply cut rise, the front of the car no longer tries to sail up into the air like it used to (very unsettling).

The front end is more tactile over rutted surfaces due to the M3 components. I'm also quite surprised that the Vorshlag camber plates don't seem to introduce any additional noise into the cabin at all! Quite happy with them.

The rear Megan arms were a good choice IMO - no harshness or noise so far. But I don't expect that to change given the sealed bearings.

As for ride height, I gave them a picture of a lowered e92 that was nearly ideal and said "get close to that, then corner balance it" knowing that the end result wouldn't look perfect and I was ok with that. I just didn't want dumped, or too much gap. This is a liiiiiittle lower than I was expecting but it's totally liveable.

[CJ421]

Cool. Better to be a little lower than a little higher, IMO. Your ride height looks good.

[ashmostro]

Agreed and thanks. Like most prosumer coils, these ASTs are shortened so they need the droop travel.

What spring rates did you go with?
I thought you were going with GC? Guess you wanted another damper

[ashmostro]

I was originally, but then started leaning towards the TCKline DA's, and then these came up used for not much more, along with camber plates and lower M3 arms so I took the plunge.

Rates are 336/672 and are extremely streetable. I could even live with a bit more spring in the front but that can always easily be changed if I want. Very happy with my setup right now.

OP, which diff bushings did you get...Powerflex 'street' or 'race'?
How about the subframe bushings? Any reason you didn't opt for the M3 ones?
Has your setup completely eliminated wheelhop?

Good questions.

I got the purple diff bushings which I think are the street. Only introduced a teeeeny bit of additional NVH. Nothing obnoxious at all. I imagine the race would be more noisy and for my purposes, aren't needed. I don't have any wheelhop but I do have an LSD which helps, along with the M3 subframe bushings (I didn't go with powerflex for the subframe).

My main goal with the subframe bushings was a planted rear end with traction, more than eliminating wheel hop since I'm more of a road racer than a drag racer. I rarely do a clutch dump. The main reason I did the diff bushings was to eliminate the driveline clunk I was getting under modified power levels. It worked perfectly.

Good to know, I have similar overall goals, so I think I'll go the same route.
In what stages did you install all the suspension parts?

[ashmostro]

The suspension mods were done all at the same time. The LSD was already in, but not the bushings.

Is it sound and/or vibration? Gear whine or road noise?
Been thinking of doing those bushings for over a year but sensitive to added nvh in my dd

[ashmostro]

Very, very, very slight whine. Can't hear it if the radio is on, or if I'm on the gas. It doesn't bother me at all.

No additional road noise or tangible vibration.
