  • Replacement for Steeltech 12" Rotors

    I'm in a bit of a jam timewise, so if anyone can help I'd be most grateful. Does anyone know what 12" (actually, 11 3/4" I think) rotors fit the Stude spindles? I have the Steeltech 12" conversion on my 53 coupe that I race, and I've worn out the rotors. Through NAPA I located a set of 1970-72 Chrysler Newport rotors (rare and pricey) that Steeltech says they use (from their website). They will mount on the spindle, but the hub is too long so the nut can't be tightened enough. I leave for a race in less than 2 weeks so I got to get the rotors quickly.

    Yes, I've sent emails and left messages at Steeltech, and I will chase them, but in case they don't get back to me quickly, I thought I'd see if anyone knows the answer to this.

    Thanks,

    John

    When I purchased my 83, the previous owner had added a Steeltech setup. He put the Avanti rotors in the boxes he got with the kit.

    Here is a shot of the rotor box.



    I can email you the same shot as it is much more clear than the photobucket shot.

    Good luck

      I'm guessing I have the same kit, bought in 1997. (how many did he have?) I should not post as I cannot remember for sure. I am positive the calipers are 78 Impala. I thought the rotors were also 78 Impala.

          More data from the rockauto website. RAYBESTOS Part # 6012R {#6012} Professional Grade;(Bendix 141025 equivalent) And Hub; 11.72" / 5 Bolts (Rebate/Promotion Available! See Promotions & Rebates Page for Details.)

          Looks like the correct size although not cheap at $110/each.

          Thanks JN

              Can't be the Chevy rotors...wrong bolt circle.

                Thanks Bob and everyone else who chipped in. Dave Levesque responded to my email today and promised to send me the part number today, so I'll post it for future reference. He says they are not Mopar rotors. I wish he would update his website!

                  The rotors are 70-72 full size Ford, and 70-71 T'Bird (AutoZone # DL 5405). The calipers are 79-91 Suburban (1.5X1mm threaded banjo bolts), and 71-76 Impala (7/16X20 threaded banjo bolts).

                    If you need wheel bearing seals, National #473010 fits nicely.

                      Dave Levesque tells me that the rotors he used are Raybestos 6012, which interchange to Bendix 141025 and NAPA 4885522. These are a one piece rotor that fit a 69 Ford Galaxie 500 and use bearings BR2 and BR6. I've ordered a pair locally and will let you know if there is a problem. Very pricey, at $159 a piece.

                      As near as I can determine, Dave's website is wrong. The 70-72 big Chrysler rotors (Newport, etc) do not fit - the hub is 4.97" and is too long for the Stude spindle. The 69 Ford Galaxie 500 rotors are slightly smaller (11.72" x 1.19" v. 11.75" x 1.25") use the same bearings (BR2 and BR6), but have a hub that is almost 1/2 inch shorter than the Chrysler rotors at 4.53".

                      Joe, I don't know if the Autozone 5405 rotors would fit - they seem to be the same size as the 69 Ford Galaxie 500 rotor, but they use BR12 and BR13 bearings, and I know the correct bearings for the Stude spindle are BR2 and BR6.

                        Judging from all this info, there was another steeltech kit. I do have Chevy rotors on mine.
                        I have the info that came from him in a box somewhere, if I could ever find it.

                          I am not positive what size bolt pattern a Stude car has {my truck has 6x7.25..yikes} but Chevy made cars in 5x4.75" and 5x5" so there may be chevey rotor that fit unless the stude cars use 5x4.5" which is small fords and most imports like Toyotas and porsches...others as well of course.

                            One heck of a difference from locally to mail order, but you gotta have what you gotta have to go racing quickly.

                              If you don't mind me jumping in. The steeltech kit I have uses 12" gm rotors 1977 Impala or Caprice redrilled for a Studebaker pattern. The bearings are 1975 Cordoba. I still haven't installed this kit yet and was wondering how you like yours? I was going to use the stock master cylinder for now. The instructions seem stright foward enough any tips that any of you have to make this a more enjoyable install would be apprecated.
