    I'm looking at the billet aluminum 2 pision d52 calipers from wildwood.
    They're only 165, but not sure which on to get

    they have 1 1/4 bore with either 1' or 1.25 thick rotor and 2'bore with either 1' or 1.25' thick rotors

    they also note go with smaller bore if you convertered to 4wheel disc which I have, but i Imagine that they mean go with smaller bore for rear caliper and not the front

    So I imagine i'll need the 2inch bore version...just not sure if I need the 1in rotor version or the 1.25' version

    ihelped a friend of mine replace his orig front drum brake setup with a wilwood disk conversion kit on his '67 mustang with a hopped up 5 litre. these are 4 piston calipres.. we had to fabricate all new brake lines for them.
    good instructions and a quality product. now the stang really stops.

    yea, ive seen the 4 piston calipers but I dont want to go up to a 16/17in rim

    these 2 pistons are direct bolt- from oem, and also uses oem rotors/pads which is what I like

    Wow, those D52 Wilwoods look pretty good.

    SSBC also makes 2 piston calipers but the thing I dont like about them is that they use a smaller d43 pad..they have a competition series with a thicker d43 pad buyt the stock d52 pad still covers more braking area

    pretty sure my rear disc kit bore is 2.497 = 78 Cadillac Eldorado large single piston caliper
    and I guess since those wilwood are 2 pistons I'd have to multiply the stated bore size by 2

    so 2in bore piston will be 4in bore
    and the 1.25 would be 2.5 inch bore
    Is this correct?

    Mike if youre going from regular factory caliper discs to these calipers, please report back with any improvements that you may find.

    Tagging on, thanks for the link.

    yes, I currently have stock front calipers, I might just call jegs or something to make sure about what piston bore I need for sure.

    I probably wont get the best I can out of this due to using the stock disc/drum mc till I can afford to go hydroboost

    I started reading about these a bit more in depth, and noticed the only reason they specify the bore difference is to allow for the stock proportioning valve to work correctly.

    Thats a simple fix, just get a summit adjustable one. My bro's 83 grandprix has one, and it works well.

    lol. Thats odd, seems like something that should be sold as a pair.

    I guess they make it convenient if you break one some how.

    I think I'm more anxious to see how they turn out than you are. Looks like Jegs and Summit both have them for the same price.

    Nothingface5384 Detail To Oil - Car Care

    lol yea, I should have realized when the price of caliper is like 165

    and the kit 2 calipers and pads were like 380
    they pretty much sell you 50 dollar brake pads with the kit

    pair without pads would be 330

    The May 2010 issue of Car Craft has an article that describes this conversion on an Olds F-85. Lots of pictures and a parts list too. Check it out!

    perhaps I will next time i'm at walmart or something
    oh and apparently you can use a d614 pad off a 94-96 impala!
    This results in a slightly thicker pad with alot more braking surface area which equals into slightly longer lasting with better stopping power

    you may also run 88-92 1le camaro rotors which are 11.86 in diameter and 1inch thick I'll do these two options next time as ive already bought stock d52 pads and stock 11'' skylark rotors
    Note: 1le rotors have a taller hub, so they'll push youre wheel out a bit
    BTW got the other caliper today :)

    just to recap, and revise a statement or two.

    Front brake upgrade:
    wildwood d52 2in bore x 2 pistion aluminum calipers (1in thick rotors)
    d614 pads from 94-96 impala (same thickness as stock d52 pads...but more braking area/surface)
    either use stock 11in skylark/gs rotors or upgrade to 11.86 1le rotors via 88-92 firebird with 1le package!

    *note* 1le rotors will push youre wheels out by about an inch
    also 1le rotors comes with 12mm studs...so you'll either have to buy 12mm lug nots are drill/press out the holes to worl with youre 7/16 studs

    anything bigger then a 12in rotor you'll have to step up to a 16+ in rim!

    Any word on performance yet?

    Are you using the 1LE's on your car?

    Nothingface5384 Detail To Oil - Car Care

    no, my dip stick tube snapped where it meets the oil pickup tube..cant get the damn dipstick to go back in.!!! lol

    but no havent did the front brakes as of yet

    I wont be using the 1le rotors as ive bought stock rotors/inner/outer bearing and outer seal prior to everything

    I will be using the larger impala pads though

    I dont feel like buying new lug nuts to use the 1le rotors anyways ...they're also like 90 plus for the rotors compared to like 55 lol
    on a side note...the firebird rotors with out the 1le performance package is only like 30 bucks...so if theyre atleast 11 in in diameter and not 10.5 that'd be a nice deal right there
    I'll most likely have it installed next weekend
