+2. My stock shifter is perfectly fine, long-throws and all, except the 1-2 shift. It feels like crap, even at leisure speeds (haven't ventured above 6K rpm yet, and always shift gently). I'm at 1,500 miles now, but mostly highway, so I don't consider the tranny broken-in yet; hope it gets better with miles. I have no doubt it'd grind if I was to shift aggressively now, like many others report. Don't understand why. All other gear shifts feel fine, including 3-2 and 4-2, but 1-2 feels notchy as hell, like something is blocking the 1-2 gate, and you hit either the left or right of it; plain weird. Every once in a long while I get it right, but man, it's just by accident. It does improve a little when fully hot, which made me wonder if it'd benefit from Redline MTL oil, like my new Accord 6MT did (they use the same special MTL oil).

Does anybody know what might be the problem with 1-2??? I suspect it's not the shifter but a burr on the gate, or something inside the tranny, like a synchro. My worry is if it's something wrong with the tranny and we have an A/F shifter, we might be f***ed. Or be forced to change it back before taking car in; what a PITA that would be. Comments welcome folks.

That looks way easier than the E46 M3 where you have to worry about the bitch pin.

I'm guessing most dealerships would probably never realize it's an aftermarket SSk instead of the original.

But I'm with you that it's not the shifter that causes the difficult 1-2

The tranny/shifting breaks in nicely. I had similar concerns and read others say it would break in but was hesistant to beleive them. Give it a few Ks and you will see/feel the difference. My 1st and 2nd were not smooth at all so much that I would often wonder if I was putting it in R instead of 1st.

I looked at different SSKs on-line and noticed that they differ in height. It would be good to try these before deciding which one is best for feel, etc. But the install looks like a ton of work as a DYI.

AP Racing Strap Drive Systems

Next on the list was brakes.

We've always been a big fan of AP Racing BBK systems. AP Racing brake discs are made from the highest quality cast iron. Curved vane technology is used to shed internal heat, and the optimized cross-drilled and slotted face pattern is developed to increase pad bite and improve cooling. Each hole is radiused, not chamfered, to reduce noise and increase fatigue strength.

The new 7100/7150 AP kits were also designed to fit behind stock 18" wheels and clear without the need for spacers, which is an added plus when our M3 starts seeing more track use.

The AP Racing engineers are the same ones who manufacture the OE brakes for Ascari, Aston Martin, Bugatti, Caparo, Farbio, GTA, Holden HSV, Koenigsegg, Lotus, McLaren, Morgan, Noble, Pagani, Rossion, Seat, Spyker, Tramontana, Ultima, Zolfe and other limited, high-end exotic supercars.

Strap Drive Systems

The Strap Drive System (Patent Pending) has been developed by AP Racing both for Road and Race applications. The standard fitment discs on many performance cars can suffer from brake vibrations caused by disc distortion. This generally occurs on fast road and track installations.



On many performance cars the typical standard disc will be a heavy duty ventilated single piece casting. Couple this type of rigid disc to a standard hub and wheel bearing and the result is any hub distortion / run out will transfer onto the disc brake faces. This eventually results in brake vibrations, usually picked up through the steering wheel.



The strap drive system offers a new take on the floating systems already in the market place. Strap drive uses a series of stainless steel straps to locate the disc to the mounting bell, producing a flexible coupling between the hub and the disc faces. This allows the disc to run true in the caliper under all conditions and also permits the disc to expand and contract without being restricted. Some current replacement discs in the market place have evolved from Motorsport applications, they typically use a drive bobbin to provide some disc float and were devised to reduce pad knock off on race cars. This system can work on a road application but there are some major drawbacks that the Strap Drive has overcome with its simplicity.

Bobbin float discs rely on a series of drive bobbins moving freely in drive slots. This movement can create wear during service and promote noise. The slots can fill up with road & brake debris causing them to seize. AP Racings strap couplings can't suffer from any of these drawbacks. Therefore service life, brake noise and also brake pedal travel are all improved.

After contact with Brake Pros (AP Racing USA), we were able to schedule our M3 in for test fitment as the caliper brackets were not completed yet with final measurements needed to be taken and custom machined.

A couple of weeks later, our new brakes arrived:



Let's begin:

Front Caliper Fitment




























Rear caliper fitment








Brake Pad sensor modification

Nice install, those brakes are awesome. Good thing they'll be on track, it sucks when they go onto a show car

New shoes were installed for last weekend's SoCal Euro event as we were invited to participate in Yokohama's booth on display.

Wheel specs:

Front: 19x9.5" VMR CSL, Matte Black
Rear: 19x10.0" VMR CSL, Matte Black

Tire Specs:

Front: 265/30-19 Yokohama ADVAN AD08

Did a quick photoshoot for VMR today with the Matte Black V713s that will be coming out soon:

















Wheels are V713s with 19x8.5 fronts and 19x9.5" rears wrapped in Yokohama ADVAN AD08 rubber (245/35-19 & 275/30-19).

Wheels will be removed and up for sale soon on a separate thread.

In the meantime, enjoy!
