Until I get the offset top mounts you want done, the ideer was to use the original top mounts.. The aluminum for your offset stuff arrived Friday.
I will be sawing it up tonight probably.

Sounds good - I will try to pull one off the car and swap in a 50 and see where it sits.

Quick question - any reason I couldn't use two of the 'locking perches' to hold the spring and thereby continue using 2.5" springs? Or another perch with a very thin dealio to locate the spring? I figure over time it might bugger up some of the threads...but considering once set I never adjust the ride height, is that really something to be concerned about? That would also allow maximum space for tires...and mean the growing pile of 2.5" springs I've got could still be useable. Just thinking out loud...

Yeah, but I might be out of work after next week. Got another Chump cage coming in also.

If you get the blue car finished that fast....I'll run a rally this year.

Woo hoo~!!!! Someone's coming to a rally!

Does anyone know of a kit or combination of parts available to bolt on aluminum calipers and aluminum hat/rotor for a E36 that will fit in a 15" wheel? The Ti w/s50 swap that I picked up already had big three hundred-some-odd mm rotors and big calipers from a 330i (17" wheels minimum), and now seemed like a good time to get a lighter setup than spending money on getting stock parts and upgrading later. Thanks.

Dave sent me some of the parts so i could try mocking up something gravel friendlier but Bitchiner---maybe even if we're lucky Soooper bitchin-er.
First look---actually about the 5th look see says the gawddamn Nazi bastids could have been nicer with the lug center to center distance... Doesn't look easy for a lug mount caliper.. Gimme some time.

Thinking somewhere in the 280-283mm range and maybe 1.25" wide..
oughtter be fine for us.

Sellholm has a tidy Alcon setup. Of course, JV will go on a tirade because it's expensive and he didn't make it but just letting you know what's out there. If John makes an affordable JVAB setup that would be a great alternative. It'll have to have green rotor hats or something, though.

Sellholm kit:

Thanks folks- Doivi, I'm no expert in Swedish, but it appears that a kit is approx. $3600? Is that for front and rear? Do you have a stock m-cyl or dual with a bias bar?

JVL- looks like radial mount is the way to go.

Here's another option.

I got non-M calipers for free from someone upgrading to M parts. Spent $100 on new rotors and got some R4 pads have raced on that ever since. Of course brakes at a hillclimb aren't a huge priority and I'm just getting started with stage rally (finished day 1 at Ojibwe and DNF'd - oil pressure related on day 2) so I'm not fast enough there to need the fancy bits yet, but haven't had one hint of an issue with brake fade.

FWIW, this also goes for using these cars at stock power levels (325 chump car, and the 328 coupe rally car) out at a road race track with no duct work on a 90 degree day. We did have the pedal get a little squishy at the 7 hour enduro race on the 325, but we're using all factory components (boosted master, fluid runs thru ABS module). We're going to try real good fluid (SRF) this weekend to see if that helps at the 12 hour...but honestly, I was the only one on the team that noticed a difference as whatever squishiness the pedal developed, it happened during my first 1:30 stint and never got worse during the weekend.

Dropping $3500 on fancy brakes may not be required for these cars, but if you've got a better engine planned, that may change things. I'm inclined to say that given a RWD car doesn't get extensively LFB'd on stage as you would a FWD or AWD car, that also probably lowers the need for bigger expensive stuff.

I don't really know the exact costs, Dave Hintz ordered all that stuff.

Here is the m/c setup we are using:

Is that the OBP pedal setup? Looks nice and engineered to get pushed up against the firewall from the get-go. I had to monkey with my tilton pedals to get them far enough forward that I actually fit without looking like a pretzel.

I would agree with that. A good set of pads with the 325 brakes would probably be adequate for most people. Going to an expensive fancy setup as shown would give a better feel and balance but you may not need that much braking power unless you're trying to compete with the likes of Will Orders.

Anybody know to what level Derik went with brakes on his M3? Seems that car really moves.

As an alternative...I wonder if stock M3 brakes could be clearanced slightly to clear a set of proper rally wheels? I'd imagine there are plenty of options out there for 2-piece stock replacement rotors.
