That's a good idea, I'll try to work on this and host it on the website. ssengineeringllc does have an online store now, finally. I could 3D print templates and offer them as well. Hmmmmm
That logic is tough to apply since cobra calipers are externally the same size with two different piston sizes between the rears and also the 38mm vs 40mm rear calipers. Most of the fitment tightness for the ATS calipers is caliper face to the inside of wheel and in that area they are virtually...
I’ve had both in my hands and test fit a wheel that wasn’t fitting on the cobra R setup with an ATS. They are both about the same dimension width wise, cobra r is slightly smaller in terms of body since the fluid passages are internal on the ATS compared to cobra R.
Keep in mind the hoses are very dependent on the year of car (fox, sn, new edge). I’m not sure what you have but sn/new edge would be a standard replacement style hose where fox would be specific to the year and also sn95 caliper swap style hose.
3/16 spacer required (I sell laser cut versions for $35/pair shipped) the pad fits great on the OD of the rotor, they hang off on the ID. Will obviously push the wheels out a bit more, but it is overall a beefier rotor.
I appreciate your efforts on the above and beyond research you’ve done, it’s certainly helped me answer some questions that customers have had with my insert kit!
I definitely wouldn’t want to see the ears of these calipers with 5mm machined off them lol.
