Vanne's lightweight/ interior modification thread

[Vanne]

These are on the way to get the SC running the best it can.

 

[Vanne]

Bit of stuff done..



CSL headers Ceramic coating ... Check..

new position for the oil cooler as the intercooler will go below. New oil coolers plumbed in.

 

[Vanne]

Part of the kit... Finally building it.

 

[Beedub]

cant wait to hear your thoughts on the blower!

Are the CSL manifolds any better than the normal UK ones?or are they just lighter?

 

[Vanne]

Hey bud, the CSL headers are the Euro headers. (ill include UK in euro in this point as there are only 2 kinds really.. Euro (in the case of the z4m, all non US cars had the same headers as the CSL M3), so if you have a non US Z4m, you have Euro Headers (which is the same as the CSL unit)

quote

-"Euro Headers" refer to the European M3 headers. They are fully compatible with Z4Ms
-"CSL Headers" refer to the Headers used in the M3 CSL and the European Z4M."

and you can easily tell if you have the US headers as they have the extra fat cat section at the bottom.

unless the UK has its own kind? oke:

 

[RedUn]

Ahh fair enough, yeah the UK and euro ones are the same! I thought there was some secret performance benefit to be had with the CSL ones. Did you look at the supersprint stepped headers? Supposedly some nice gains to be had there?

 

[Vanne]

I sure did look at them, however, there's a little exclamation point on the ess website when shopping for SC. "Not compatible with stepped headers", why? I have no idea.. but there it is.

 

[Vanne]

And then, finally... My Penske rear custom suspension finally shipped from my mates joint in Abu Dhabi.. couldent even go and collect it, had to ship it due fucking covid..

Anyways.. here it is in all its glory...







Freaking amazing set.. custom hats, custom base, custom mounts... Love them. Makes my KW clubsports look like toys.

That is some epic s**t right there!

 

[RedUn]

Suspension porn :evil:

Diff refurb took an other direction, bought a proper race LSD to swap into the casing.

But have decided on 30/60 ramps.

 

[BMWZ4MC]

Why rally / gravel not the maximum grip circuit set up?

 

[Vanne]

It's s custom setup, not just off the shelf. I had a 4 hour long conversation about what sort of track/race driving that I do and this is what was recommended.

As for ramp angles I can tell you that 50°/65° ramp angles are most forgiving option and excellent choice for grip driving especially for less experienced driver, while 30°/60° ramp angles provide аgressive lock on throttle, but soft on engine braking.

So for our car we've gone for a more aggressive race track setup.

 

[BMWZ4MC]

I don’t know much about LSD setups, but aggressive lock up under hard acceleration and more benign behaviour on the overrun (and therefore under braking) sounds like a good idea to me

 

[Vanne]

Yup, i just hope that the pre-load and balance are correct. id hate to be oversteering like a mofo if that isnt correct. Had a long discussion about that too.

 

[Vanne]

And then we started with the race dash...

Really happy with how that turned out. Just roughed it in at the moment, will need to sort out the gauges and panel fitment.

I have some ideas on that, but will need to be fleshed out some.

 

[Vanne]

Racingdiffs race diff arrived..

Holy s**t, comes with brand new output shafts.. unexpected..

 

[MrPT]

That is the most hipster packaging for car parts I have ever seen. :lol:
