Did you go through with it? Would you recommend?

It's probably the last mod I'm considering doing (I know everyone says it should be the first) and a lot of people saying its worth it without going into too much detail.

The actual shifter or pedal doesn't feel different or harder right? Its more to do with a slightly more consistent engagement point? But is it a shorter engagement point now? I'm basically looking for a more consistent engagement point mainly in 1st starting off and from 1st to 2nd, which I feel the g87 6 spd sometimes struggles with. The clutch is pretty easy and forgiving in stock form so wouldn't want to make it more on/off like a porsche gt car.

Im also considering doing a clutch stop but don't know if anyone would recommend? I'm hesitant because the friction point is pretty early in the pedal movement in the g87, at least compared to other manual cars I'm used to. (porsche 911s friction point is a lot later in the clutch pedal movement which would make a better candidate to install one on imo. Going right from my g87 to my 911, I would always over rev the first few shifts in my 911 expecting the friction point to be much sooner from g87 muscle memory).

I did, yes.

I also have a clutch stop with 3 of the 4 spacers in tact. Both of those are the best mods I have done to my car, making it very enjoyable to row through gears and quickly shift.

I highly recommend this mod combo to anyone comfortable with manual driving, as it will take off the “training wheels” a bit.

nice. think the cdv delete is gonna be one of next mods. thanks!

just one last question:

have you noticed a less jerky/more consistent start off in 1st AND a more consistent engagement point/shift from 1st to 2nd?

Yes dramatically after doing the CDV delete.

Things you’ll notice:
1. Consistent 1-2 shifts without as much jerking motion.
2. Rowing gears at high speed without any sort of delay.
3. Clutch catch is super consistent and doesn’t move around depending on how you drive, it’s just always up high and nice.
4. Overall happiness

That's what I was hoping to hear. Thanks for the info! Def the next mod on my g87.

Do you have a link to what you ordered? This sounds like a good value, though I don’t mind the current set up at all.

There is nothing to order for the CDV delete unless you don't have a pressure/vacuum bleeder. You're just removing a restrictor.

This is a no-brainer, must-do-mod. Zero downside, all upside.

[CadolinaRipr]

This is a pretty easy mod that makes a world of difference. Just do it. My 2 cents.

Have added it to list when get HAS installed this month hopefully! Just waiting on wheels to arrive.

Genuine question. If it is constantly deleted, why does BMW engineer with them in (CDV valve).

As "training wheels" and for "comfortability"

Pretty much for people to have a safety net for improper clutch releases and mitigation against traffic stalls.

My opinion: toss to the wolves or drive an auto if you need it lmfao.

I forgot to get back to you- I spoke with Ron and am in the order queue for a SSK (25% reduction with a 90a bushing for a weekend enthusiast approach). It’s been about a 3 month waiting period so far as they are all hand made. I am very eager to get this thing!

Will it take a second to get used to the change?

Took me like 5 minutes tbh. It’s just like driving a normal manual car without any sort of clutch lag, so essentially unless you learned manual on this car, you’ll be just fine.

Nah, been driving stick since my Mini S in 2002. Had a bit of a jolty test drive on pick up of the M2 coming from a Mazda 3 lol.

With the valve in place, the risk of damaging a driveshaft or stripping a gear in the gearbox is much less when the clutch is dumped rapidly with no slip and the tyres don’t spin. Basically reduces shock loading to the drivetrain.

I expect if the CDV is removed and a car is taken in for warranty work due to a gearbox or driveshaft failure relating to shock loading, it would be a good reason for BMW to deny a claim.

Does a clutch stop remove pedal travel at the top or bottom?

The bottom

You’re right of course.

But, in my opinion, the fuckery required to trash this gearbox, or something in the drivetrain, with or without the CDV present, would come back to user error. In other words, if you do something so aggressive that parts are breaking, I don’t think the CDV will do much but maybe soften the blow (ie. wearing a helmet jumping off a cliff without a parachute).

The massive improvements in driveability, shifting and clutch feel far surpass the risk (for me).
