GM Brembo Caliper Identification

So more times than I can count customers have miss identified calipers , these can be expensive mistakes. I hope this post can clear up some of the confusion and shed some light on some of the subtle differences that these calipers have. First let`s talk about front calipers. Each Brembo caliper is created to fit a certain rotor size and for the most part we keep them on that intended size to keep things simple. So starting with the smallest 4 piston the general uses, the “JL9” or ATS is the base caliper on the JL9 brake optioned C7 corvettes and also that same caliper was used on early ATS Cadillac’s and most recently the V6 6th gen Camaro w/ Brembo option. All of these calipers use a 12.6 inch rotor, however each rotor has its own differences, the C7 rotor is the one we use with all of these calipers for most conversions. Reason being is that the c7 rotor has the legacy pilot hole size (2.78) and the low hat depth of 2.010. below is a list of the rotors critical specs for each C8 JL9 =12.6 2.010 hat 5 x 120mm 67.5mm Pilot 14MM studs C7 […]

The Holy Grail of 3rd gen spindles

Bet you were thinking 1LE ? right? Heck no..those were std 3rd gen spindles modified by the factory..same thing we do to them to bring our conversions to life..it`s better than that ! Just look what these are going for !?? no…. Belltech 2 inch drop spindles. Long discontinued, highly coveted and rarely for sale. Oddly enough these were only on a car for a short time before being put up and ultimately removed from the car they were installed on to bring it back too original. The owner of these would like to see them go to a deserving build and knows they are worth more than original retail ..sealed bids ? best offers ? a reserve amount is in place.. Q’s Idea`s .. lmk

6th Gen ZL-1 and CTS-V3 conversions

Yes those massive 390mm / 15.35 rotors and those Huge 6 piston calipers.  These brakes command respect, the shear mass of the rotor and caliper dominate the poor little 3rd gen spindle.  Staying current has always been a trait to keep new business flowing and I have to admit, I’ve had these brakes sitting here for a while now. Not that I hadn’t tried swapping them onto all the common spindle set ups I do but I kind of zeroed in on the 3rd gen first and after several attempts to graft them in with all the usual mods- I came up short.   I’d pull them out every now and then and try a new idea and like past attempts decide that the necessary mods are too extensive or involved.   I try to make these brakes fit vintage era spindles as simply as possible and that had not happened until today.  Sometimes the easiest answer is starring you right in the face the whole time and you can’t see the forest for the trees. So with the solution in hand now I can safely say this one is conquered. And I can make it fit all the other spindles too.. […]
