Well, given that on their own website, the remote is an option with the OG M2 MPE and not the M2 Comp MPE, I'd guess whomever you spoke with was incorrect.

Waiting on my Vorsteiner Wing Blade and spare trunk I bought to come in.

Just had a MPE installed today. Is it worth $5k? Not sure but it looks and sounds better. I just purchased the car last week with under 600 miles on the odometer. I drove about 200 miles in the car but it was enough for me to know the stock exhaust had to go.

So I'll likely replace them every 2-4 times I swap pads since I'll do it several times a year going back and forth between street and track pads.

I would be careful . . .

On my 1M I reused my strut pinch bolts twice when I installed camber plates and then later coilovers. I had no idea they were single use only. They are aluminum and can only hold their specified torque once. I got away with it the first time, but when road testing the coilovers, I felt and heard a loud snap when turning right into my garage . . . the drivers side shock had rotated enough that the sway bar end link got turned into it and snapped in two! That was an easy fix (Turner adjustable links FTW!).

If you are doing track days, and those caliper bolts are meant to be used once, their failure could be catastrophic, and could fail more easily due to the heat cycles and stress.

If you want to hear my CS with Akra back and AA Equal Length Mid, let me know since you're in the OC and I'm not that entirely far from you.

I appreciate that. Like "most" CS owners considering a new exhaust it will "likely" come down between Akra and MPE. After a deep dive on both systems I went MPE for the OEM factor and no valve control remote required. However I do think the Akra is slightly more visually appealing and the fit and finish "might" just be a tad higher even though MPE was reportedly developed in partnership with Akra

yeah, I'm not surprised by the partnered development. But the MPE exhaust overhang, though slightly looks better under the diffuser, is grossly still large and unappealing compared to the tuck the Akra and a few other aftermarket exhausts have to offer.

Agreed.

You don't need a valve controller for the Akra. It runs off the stock actuators that are transferred over so valve control is automatic like stock. I agree Akra is visually better looking because of beefier tips but the tips do bump the diffuser during normal use, and will cause scratching on the carbon fiber (both tips and diffuser). It isn't visible installed though. MPE might be more valuable long term for this car because it is OEM.

Just an observation - while the MPE on the F80/2 was titanium I understood the MPE for the F87C is steel (except for tips). Regardless, the crack experience I had with the MPE on my F80 turned me off. I think there is still a question overhanging quality and resale on cars with MPEs. I know I parted out before selling my F80 and its problem/reputation meant I didn't get much for it selling separately (1/4 money back). The Akra is titanium and doesn't have that kind of history.

Good to know. I watched the Remove Before Race video when he installed it on his CS. He had the remote so I assumed it was required to open and close the valves. I think the remote is also featured in the Chris Harris video on his car that has Akra? Anyway you can't go wrong with either exhaust. And IMO both systems are a big improvement over stock. Now on to spending money on other mods...

if you purchase the full akra system(link and exhaust) the remote is included with the full set.

I didn't get the remote system and I'm very happy with the normal flap control mechanisms operating. Thought I'd wait and see if I wanted to add it later and long term answer has become a big donut after 6 months.

[to_riffic]

The remote, at times, does require a few pushes on initial startup to open or close the flaps, so that is my only annoyance with the remote because it has it's own wireless signal it keeps to pair with the module in the trunk.

Yes, the Akra sound kit comes with the link pipe, but it is only to have full control over the valves. It is not needed to run stock automatic valve control. I didn't install it because it is a pretty invasive installation and there are easier to install solutions on the market (ie, VSC2).

Update on lowering with H&R sport springs

After a few weeks of local and highway high speed driving I have decided to switch to the BMW HAS.
The rear was perfect but front just a little too low. The stiffness of the springs also really accentuated road vibration at speeds 80+ FYI originally the thought was 5mm spacers were not perfectly aligned so switched to 10mm with lip but no difference. At 10mm there was slight wheel poke in the rear. Ill go back to 5mm with the BMW HAS

Timing was now as I ran into some bad luck with nail front passenger tire and the rears were getting close so Ill change all 4 tires.

With respect to the CDV delete could not be happier and a must do mod IMO
The Porterfield R4-S pads feel very good with no noise or clicking. Approx 50% less dust front and 70% rear.

I haven’t really been driving it. I have been holding off for PPF. I’m going to be excited to take it out for real!

Are these the BMW winglets for aftermarket? Does anyone have some history on the aftermarket ones for looks, durability etc.? At roughly $200 vs the OEM at $1200, I'm curious as I want a set...

Those look to be the BMW ones. I have the same, purchased from a seller on this board. He seems to be have another set his selling at the moment.

You have the OEM ones? I can't seem to find this other set available. You mind sending it my way?

Who's winglets are these? I'm looking for a pair, aftermarket if they're good enough, or discounted OEM.
