There is a new lightweight option for those that want to simply replace their stock Delco-Morraine single piston iron calipers with aluminum dual piston calipers. Wilwood has now produced a direct bolt-in replacement for the D154 pad calipers using the 10.5" x 1" rotors.
Thought Id pass this along. These are going on a very lightweight application I am doing in a 1967 Austin Mini Cooper build where I am using my old Camaro spindles and brakes up front. 4.6 lbs each caliper loaded.

thanks for posting that. Im going to put these at the top of my list. I wonder if they will make a set of ebrake calipers. Id love to upgrade from my weld on kit
A very interesting upgrade. I'm a big fan of high performance parts that are "plug 'n play" with stock sizing, without cutting, grinding, adapting etc.
I'm confused on two issues though.
1) Those specs on their page say min rotor diameter of 11.0 inches. Would our 10.5" brakes qualify for this?
2) How does one go about choosing the right size piston? I'm seeing options for 1.62" and 1.12"......Are these interchangeable and is one always the better option? Basically what would somebody with non-1LE disc brakes (like me) ask for when ordering?

Hi Gordon,
1) Wrong info on Wilwoods part. Same pads the cars have now and same fitment- so of course it will work.
2) Total volume on Iron calipers is 4.43. The 1LE PBR calipers are less with 3.53 total volume piston area. THUS- using the Wilwood dual piston with 4.12 would be perfectly fine for bias and just very very small tad more pedal pressure which is good for modulation and overall feel.
Also, these have been around for years, These are only single piston spec racing replacement calipers of the actual Delco-morraine iron caliper. pretty much the same thing in piston size, etc...only made of aluminum and much much lighter then the iron ones.
Since these don't have a dust boot, thoughts on a weekend/fair weather car? Also, how would these stack up against an LS1 swap?
This is why I won't use Wilwood calipers on any of my street cars. I've also been told by a PA inspection mechanic that calipers without dust boots are not allowed (won't pass yearly inspection).
A LS1 swap is much better as the rotor is both thicker and larger in diameter.

It is all about corrosion. you guys in the bad states obviously have severe problems with all of the car rusting out. We do not have issues like that in So Calif. so obviously dust boot to help prevent corrosion is not an issue. I do not even have window wipers on one of my daily drivers. I ran Wilwood Radial SL6piston calipers with out boots for a decade no problems. I had some dynalite pros on the rear of a dune buggy that had problems from dirt and water extensive use. hey would freeze up after sitting and not being used for months.That buggy saw very muddy situations.

they make a full kit that bolts on. for under $390 if I remember. this is a nice upgrade. I did it 3 or 4 years ago. when starting the redo of the car.it drops about 8 to 10lbs off the brakes also.
but as upgrades go.. they never made it on the car for long..cars not done and a upgrade was done yet a 2nd time..
this kit drops 38lbs off the car..and I don't need the wheel centercaps...

That willwood kit is drag race only. That is not suggeted for road use. Years ago I inquired about those wilwood drag kits and was refered to Doug at Global West. At that time Doug was contracted by Wilwood to make some road race worthy hubs tht would not crack under cornering strain as those hubs will do. Doug had that CAD file still and ran me a duplicate set for my car back in 2003. I was the only other person to get a set of those other than the Wilwood G-body 4000 lb road race car they specially designed them for. The only other viable option out there right now in aluminum hubs is Core3.
The difference is Articwhites rotors are not vented and the hubs are light weight for striaght line use, not cornering. Those rotors will not accept heat in multiple stops. Made for one time stops then cool off for a while- hence drag race use only. they are only .35" thick rotors and those aluminum hubs are thin backing unless they have redesigned them in recent years.
These are 13" x 1.25" think vented SRP rotors made for track use.

yes.good info... as my car is a drag car/street car..and is always looking to drop a lb or 2.
cars on a diet..anyplace the lbs don't need to be...and my rotors are Vented..

LOL, I just checked wilwoods site. looks like they copied my kit. I piece mine together years ago and custom machined the brackets and hub centric spacers along with Dougs hubs. I still question Wilwood using those hubs they sell for road race use(cornering) I would like to see a better pick of the back site of those hubs to see if they are radius with thicker aluminum. http://www.wilwood.com/BrakeKits/Bra...isc+Brake+Rear
things are a bit better now... this rotor set up is .89 and vented. just a tad under stock.
and the hubs are billet alum.. not road racing the car.. but its fun on the street..

Im just curious if you have a pic of the back side of the hub. I think it was Jerry (jerrywho) who told me one time privately when we were at the track together years ago that he cracked one of those early wilwood hubs.
they have 3 diff set ups. as to the way they go together.. safty wire..no safty wire. and type of bolts. have looked at all they had before the upgrade.. I was a bit put off by the way they bolt together...but I always check the car out top to bottom with aftermarket parts..keeping an eye on things..weekend to weekend.. will get a shot of the backs in a few min..had to put some power in the phone...
Thank you. Just a word of caution-those are still the same design that crack. They crack right across the 5 star extentions where the other silver alumunum piece bots together. They are not strong at all to take any kind of prolongs road use. I am shocked wilwood is putting themselves on the line like this. They had diclaimers on their wesite for years that I no longer see. Wonder if they are making them out of 7075 now.

as the car is not a fulltime street car.. fri/sat night at best.. and I have not had the car on the street in over 12 years..(locked away) I will keep an eye on anything after market..when it is doing the car shows/drag strip/cruse night thing...
anytime its on the street its driven as if by a old lady...give or take a romp in first/2nd gear...some times...
better material nowdays makes things hold up better/longer. but I would like to see them made from steel..

Thumbs up. That is how that kit is intended. Just a caution for anyone else thinking otherwise.
I will see if the boys at my old shop can make the hubs out of the titanium or stainless steel we have... (I use to make jet eng parts)...lol shop comes in handy. can make anything..we/Thay.. even make parts for the 30mm bushmaster cannon..ya say.. race car part can you make this..they are all over it....lol
you would be surprised what a good pizza lunch will get you..
