Not sure if import taxes etc would push the price up even more though.
I did toy with the idea of those as well, but i didnt want to go up on spring rate which they recommend and are valved to suit, maybe the lowest spring they do (400lb) might be ok on road though, i would want front and rear with springs etc though and it was going to be more than i can get Ohlins for so deceided to go stock Koni again for now.

Ahh I see - I thought those rears were just Koni's but shorter.
That's the trouble with looking at the American forums, I'm not familiar with the brands and usually get half the info!

I'll put the zipties back on for a few days then take a measurement to see how much extra travel is used. Another option if space is really tight could be the Dinan top mounts -

Yeah the rears are modified to allow incar adjustment and they revalve to suit springs supplied, fronts they really go to town on and again revalved to their specs but also threaded to take aftermarket coilover spings and make them height adjustable, nice setup I think but pricey due to all the work that goes into them, on rears they supply height adjusters for rears as well, see link - http://www.tcklineracing.com/webdocs/It ... ils978.cfm" onclick="window.open(this.href);return false;

I think the Dinan rear mounts are only required if going mega low, as you've found a little off the bumpstops makes plenty of travel for normal ride height cars :D

Interesting stuff again :)

Here's a good review of Bilstein B6 & B6 a10:

http://www.m3forum.net/m3forum/showthre ... 953&page=4" onclick="window.open(this.href);return false;

There seem to be limited suspension travel with B6 in front compared with koni yellow, this can be compensated with GC camber plates or cutting the bump stops:

Could this be the reason why the Birds suspension feels harder in the front too?

Yes ive read all those and been chatting with Dal quite a bit over on M3cutters, he has nearly as bad a suspension swapping disease as me :lol:

As you've found internal bumpstop on the inverted dampers can easily be trimmed, its just a question of how much is safe I guess, I felt the Birds fronts could of done with a tweak myself as there isn't a huge amount of travel before contact starts, i know Kevin at birds said they get Bilstein uk to do some tweaks once dampers arrived from Gemrany and i suspect that tweak the bumps might be what they do, i have no proof though its just an idea.

Sleeves pull off the oem bumpstops easy enough but the birds bumpstop is a little smaller OD so wont hold the oem sleeve on, you could use cable ties to hang it from the cup washer at the top, i have actually done this on one side as my modified bumpstop first bonding didn't hold 2 parts together and sleeve fell down, will get a picture when im next under there.

Here is a picture i found on my phone earlier (well 2 pictures spliced together), it shows the difference in rear bumpstop lengths with OEM (from a E82 which was same length as my E87 but slightly different nose shape) as longest in middle, Birds B1 on the left and my modded E87 short one on the right.

You're right Ian, the question is how much to cut. In that aspect the GC plates might be a better option, there's 7/8 '' extra suspension travel, possibillty adjusting camber and the bump stop retains its full lenght and progression, but it costs extra cash :D

Here's a fierce debate about Dinan mounts :) :

Another option is the Bmw E90 poor road package, these 10mm spacers are fixed between the springs and the car body, but they raise the car also 10mm.

Nice pics, they show a clear comparison. The Bmw seems to be progressive, the Birds bilstein linear.
