Vanne's lightweight/ interior modification thread

Love that ARB! I've been rethinking my setup recently. Do you know if your supplier has hollow/adjustable bars for the OEM pickup points?
 
Pretty sure they do Liam, have a look at ground control arb's mate, this one is a custom race version, but they have many.

Do the helper springs not go at the top?
 
They are at the top, these are in inverted. Lol.. :thumbsup: have to still see which way they will be installed once the wheel is on properly installed. (They are only loosely installed at this stage and only to stop the suspension arm from hanging) but to answer your question, helper springs can go either place. Top or bottom. And these shocks can also be installed either way, upside down or right way up, just depends on how you fit them and for what reason. These have provision for remote canisters, and as such would be upside down, but as I have no need for that, leaves me open to install which ever way I like. :) Which might even be this way as the main body will see less fod this way.

Interesting never seen suspension you can fit either way before! Certainly different that! I'd fit them the other way to protect the damper rod from picking up damage?

Fod, are you in aero? :thumbsup:
 
Yup, sadly as it's probably the worst sector to be in ever. All of mates have gotten fired over the last 8 months. :( I'll have a look see after my wheels are fitted, depending on clearance.

Thought so, same here, bad times, lots going over here too, it'll be back though!
 
I sincerely hope so mate, only surviving as i am on the 777 fleet, nothing to do with skill or otherwise, just luck of the fleet. not sure how were gonna go though the 380 is like the Titanic, and will most likely take all of us down with it as it sinks down into the depths of stupidity. :headbang:

On the upside, my Injectors arrived today.. :D and my diff is ready to be picked up... :thumbsup:
 
Meanwhile...

Really looking forwards to this hooking up.
 
Not sure Liam, but it's within spec from the lsd manufacturer. I queried it too, as normally around 0.06 to around 0.03. but racingdiffs said that this was in spec for thier race LSD.
 
I'm pretty sure the M diffs are looser than most. Up to 0.15mm IIRC. I'm sure yours is bang-on.
 
Yeah hope it's fine, I feelt it when I try to turn it, there is a little give, but not much, I'd call it a millimetre. But it will loosen up some no doubt. Bolted her up today.. finally starting to get back together.. I need to remove the bump from the spring perch as the upper control arm will probably tough it other wise.. :thumbsup:

Have you considered running without a RARB Liam? I know a lot of the E46 M3's run without one in the Kumho championship.

When I measured the roll stiffness at work the stock RARB only added a 6N/mm increase in roll stiffness per corner. In your quest for weight loss it may be worth running without and making a small step increase in rear spring rate to compensate for this.
 
Interesting - thanks Jono. I have a 21mm RARB at the moment. Assuming I can get out for some pre-season testing I'll disconnect it and see what happens.

Ironically, I replaced the drop link bushes and painted the brackets over the weekend!

Nice, I fitted the H&R adjustable bars to mine in November (27mm front, 21mm rear). Currently have the rear disconnected and it drives really well, but the trackday I had booked at Cadwell was cancelled so sadly I haven't had chance to give it a proper test.

I plan to measure each position at work, including disconnected. So when I have the data I'll put together some graphs and upload them to my thread.

FWIW, the E46 M3 CSL uses a 30.8mm front ARB - and it's hollow!

Yup, just not the easiest item to get your hands on. I like having the adjustability available that the H&R offers also.
 
youll probably initially feel its easier to drive with the rear arb missing/un-attached, but that just means that your rear suspension isnt set up correctly. Alex has many posts in regards to this on the /other/ site. might be worthwhile reading up on that before dis-counting your rear ARB.
