Wise words
Man you have LOADS of question Mark - go for a drive
Great to see such enthusiasm though, it's like you are possessed by The Z Spirit - are you booked into the Silverstone Classic on 21st July yet ? You'll go totally mental after you've wandered round a few hundred Zs 8)
Then got me thinking about what our options are??Bing said:Wise words

Thats because I'm driving / cleaning it during the day, then in the evening trawling the internet on it
I have really been bitten by the bug though. Thing is this is my daily, I'm not normally into my daily like this (I normally save it all for the drift car) but this thing has gotten under my skin. I think a lot of it is down to this forum / club and all the members. :ilz4f: Everyone is so friendly and willing to help out, there is a good banter and as far as I've seen none of the keyboard warriors / cocks you get on a lot of forums.And I'll have a look into that Silverstone event - but as you have said, I'll be losing the plot after being surrounded by loads of them! :dance2:
Where do you buy tickets from? And is there a club stand or is it public parking (I suppose I should just look for the thread eh? 
)
It's all here : http://www.z4-forum.com/forum/viewtopic.php?f=14&t=32876
Apart from my rear rotors, my brakes need some major attention. After pricing up things I realised I was getting towards about half the cost of a front and rear ksport kit, so that's coming next month
I'll probably get my calipers refurb'd by biggred and keep them if I ever need to refit to the car anyway but I thought why not?

+1.. This was my recollection too
They are, of course our Z4M's are a lot heavier than CSL's.

I guess you could find solid calliper bushings although i don't think i've seen any for our cars plus they would need frequent maintenance to keep them lubed to prevent them from seizing due to road grime and whatever.
No readily available cooling hose kits are available for our cars either, no room without cutting into the bumper and restricting the max steering angle, a custom job that is. The "brake cooling ducts" (not sure they really perform as brake cooling ducts anyway) cannot be used as the opening is much too close to the tire...
Apart from #4 and #5 i've had all the above done and the one thing that proved the single best upgrade has been the brake fluid. I've used Endless RF650 before which i thought had amazing endurance, albeit very expensive and am now using Motul RBF 660 which is pretty much as good but a lot cheaper to source here.
M@r]{, any kit that will fit an E46 M3 or M3 CSL will be able to be installed onto our cars. You might have fitment issues with the stock wheels though necessitating the need to install spacers or different wheel models. The AP Racing kit specifically made for our cars has a slightly thinner calliper than their early E46 M3 kits making it fit behind out stock wheels without other modifications. One thing to note regarding using kits intended for other cars is that they may have been designed for the particular brake master cylinder capacity of those cars and while they will certainly work on our cars they might not be exactly tuned to a Z4M. Might not have the proper front/rear brake balance for example. That said, i've seen plenty of cars with M3 or other kits which work fine and report no problems at all. Just something to think about, that's all.

Do a Google for "BMW solid brake bushings" and you'll find several different suppliers in the US and the bushings cost approx $50 per axle. It's a universal kit across many different BMW models because most use the same Part Number 34 11 1 157 038. I've had them on my Z3MC for 5 years now and had no problems with them. I spray a little copper grease on them, whenever I take the wheels off.
Make your own. All you need is some flexible ducting pointing forwards under the car to collect moving air and the other end needs attaching to the dampers (with cable ties) directing to the aperture in the disc. You can use the front ARB as a point of attachment for the inlet. Mine cost me £15 for 1 metre 2" ID (do a search on ebay for "brake ducting" to find suppliers) and I made my own brackets from bits of metal that I had lying around. They don't have to look pretty because they're out of sight but ducting will improve the "duty cycle" better than anything else.ga41 said:

This is how I've done mine on my Z3MC and the parts have been on for several years now and had no problem. The inlet is attached to the front ARB. The air comes from underneath directly off the engine undertray. I found that the key to getting them right was having the ducting just long enough on full lock so as not to be stretched and also routing them so that the ducting doesn't have to make any 90 degree turns. I've used a digital pyrometer to test their effectiveness using another Z3MC without ducts as a control and they really work! I'm sure I'll find a way of doing something very similar on my Z4MC.
