I've been on a bit of a shopping spree for my 40k basically stock M235i and I'm looking to complete the pile of parts before I tear the car apart. M performance exhaust is already installed

Mad stepped core HD FMIC
M4 take off front strut brace and carbon brace
M2 oil pan/pumps
034 crank seal guard and trans mounts
Sonnax ZF 8hp45 valve body tune up.
Quaife LSD
D088 inlet and FMIC to tbody tubes
VRSF high flow catted downpipe

I've been reading everything I can find but many of the intake reviews/suggestions don't specifically address the carbon brace clearance. What intakes have you guys used on single turbo N55s that clear the carbonfiber brace?

Has anyone installed stiffer differential bushings, and if you have, what are the NVH effects? I'm considering just using inserts in the stock bushings, but I'm doing the rebuild myself so it's a simple enough thing to work over the bushings at the same time.

My goal is to make a track demon that isn't going to drive me crazy on the road.

I'm sure I've forgotten something but thanks for reading.

not sure about what intake will clear the carbon brace, but the BMS does not use a heat shield so its a safe option for what you are looking for

lots of good charge pipes on the market, if you want the best value, get the MAD charge pipe, if you want the best quality, get the evolution racewerks

Updated OP with new parts and removed answered questions.

CTS or RK Tune intake - MST V2 or BMS inlet.

I really like the Rk but since the car is meant for the track I'm worried about covering up the radiator so I'll likely go for the CTS.

Is your car an automatic? I haven't seen any issues with the RK Tune and over heating - one guy on the M2 side didn't either when he was tracking.

But I thoroughly enjoyed my CTS intake, you really can't go wrong.

Is he running an OG m2? Got a link?

The reason I'm asking is the carbon brace clearance.

I'm pretty sure the stock intake will clear the carbon brace. Fritz Ramos on youtube does it. Other forum members report the NVH from getting stiffer diff bushings is very noticeable. I probably owuld stay away from getting anything higher than 90A.

While you're down there, I would do solid rear subframe bushings. hardly any NVH increase but a huge increase in performance.

How come a quaife LSD over a wavetrac?

[Coupsoup]

I really like the fully geared setup, and alittle novelty is cool. I've built hundreds of differentials in my time but I've never built an ATB style differential.

Considering all the reading I did i'm surprised wavetrac got by me honestly. Just read up on them, seem pretty good.

Might have to look into them a bit more.

As far as the intake goes, I'm not sold on the whole 'stock intake is good' argument. I think the proofs are out there that a well designed intake is better. I'm positive it will clear the brace, however, so I've ordered a panel filter for the time being, as well as modifying the stock box.

If you shove a 3 inch hole saw through the front of the lower air box it magically becomes a m2 air box for free

[Coupsoup]

My thoughts exactly!

Yes.

Perfect place to start - I strongly suggest the inlet though, it really does make a difference.
