Good to hear you can drop a disc in, saves me posting one to them. Can you ask if they can do a floating disc rather than just a bolted one?
I have been on the blower to compbrake aswell and am in the process of setting up a possible group buy for the 280mmx22mm 2 piece discs! Looking at getting the price back today for a possible minimum order of ten units.
I'm going down to Compbrake this morning as I have some track rod ends to pick up but can't leave my disc with them as it needs to go back on the car but hopefully they can get the measurements they need. Btw, how do floating discs differ from the usual bell setup?
Floating discs sit on lugs and have a small amount of static movement to the bell. They are not bolted hard. This means they can expand with heat. If this gets fudged in conversation, let us know.
Looks like at least 3 of us have been speaking to them independently about 2 piece G60 discs, hopefully that will help show there is genuine interest in them. When I spoke to them I mentioned a group buy and they seemed open to accommodating one. Look forward to hearing how you get on today.
I've not spoken to them. I've no idea whether they make discs (doubt it - buy in?), but clearly they'll make bells. Whatever, disc origination is pretty key here. The bells I have could be supplied. BG Developments are the alternative, AP use them all the time. With that, a generic AP disc could be sourced (if avail in 280) and inherent quality is then more transparent.
I have just spoken to Brent at compbrake and he's got the measurements today of one of us that dropped a disc in. He is also going to develop some mk2 16v wishbones that will be fully adjustable and Rose jointed when I send him down a wishbone next week so keep you ears peeled on these too!
I've been in today and seen Brent and dropped off a G60 disc so it's underway. I've asked for floating setup if possible so he's going to try and sort that. I also left a mk1 wishbone with mounts and have expressed interest in getting some scch style arms made up as you mentioned gingernuts.. I've explained to Brent that demand is out there for the right products in the mk1/2 golf range so hopefully they can come up with something. I'm collecting the disc Tuesday morning so will update you all then.
brent seems confident that we should be able to get a good group buy price so will have to start looking out people who are interested. did you manage to find out whos discs they use as i presume they just maufacture the bells?
Fully floating 280's with radial mount 4 pots? mmm Great effort gents, floaters are the missing link - - FWIW Momentum Motor Sports offers conventional disc mount 4 pot kits for MkII & MkIII's with the latter's front hub - - radial mount Wilwood 4 pot for 156mm disc; lug mount for 280mm disc, the latter 4 or 5 stud; both utilise a 22mm master cylinder, claimed 2.2kg reduction in un sprung mass, Can$675 ea kit http://www.momentummotorparts.com/store/brakingmk3.asp (Chris, whats up with my paid membership status pls?)
Are the Reeves' front brakes fully floating, partial, or? Chris, Presumably the socket headed capscrews in these photos pass through radially elongated slots in the discs, thereby permitting the discs' radial expansion & contraction relative to the aluminium bell, and retain reasonable axial alignment, again relative to the bell, due to tension applied by the special clips under the head of the capscrew? In other words the capscrew, flat washer, spring clip, and nut assembly do not clamp the disc firmly against the bell due to either a hidden specially shaped nut or separate bushing/spacer, which is marginally longer than the disc is thick - - similar to the American sourced brake assy posted by steve r, except that system lacks a tensioning spring and therefore axial movement? Oh, and there's a few grams unnecessary unsprung weight there if all bell to bearing housing fasteners protrude 5mm or so past the female thread as shown
I believe the part in blue to be the case, but have not had these apart myself I'm sure the grams comments are in gest! When a rather unaerodynamic ~vertically-screened silhoette is being forced through the air at high speed, it's sheer engine output that's needed to do it. The grams at this level make negligible difference, plus a greater weld surface area and serviceabilty has been achieved!
FYI. I just picked a spare set this morning, these are Zimmerman VAG Sport cross drilled disks. With cgti discount this are now 97+VAT.
Once more very late, speaking with racing brake specialists let appear hat fully floating discs are NOT necessary under 330 mm, minds differ At 330 mm.
It is a very difficult science to follow. However, a Wilwood / Rally Design non-floating ~300mm set up using a disc quality that cannot be verified or tested in any way, warped on the Reeves Golfs. These were switched for a similar size of floating race Brembos, and have been perfect since. Implicit in the equation is the distinction between the higher-end Brembo parts quality and the more budget aspects of Wilwood parts.
