a standard 6061 might be a bit soft, but in T6 it might be ok...the advantage with a corolla is is light and we run relativly small tyres.. so the resistance in the opposite direction of the cars velocity i dont think would be that outrageous.
yeah im thinking 6061 is abit soft, asked afew people in the know and they would probley avoid using it.
especually in a drift car where the hand brake is slamed on rather harshly at some desent speeds.

Someone QA my calcs please.
Because it's only a simple simulation I'm running I can only direct the forces up/down/left/right which is ok but to I feel like I should be modelling it with both the shear force and torque?
Ugh, what I need to do is "attach" a "caliper" to the bolt holes and apply the force to that. That'll give me a more accurate stress loading on the model.
With materials, I have no idea what's good and what's not. I know that bikes are 6061 or 4130, sometimes 7075.
Also, that is office 2003 for those of you that remember. Running a 2006 version simulation software and listening to music from 90's snes games off an IDE hard drive. Totally living in the past still.
Did some more simulations. Changed the caliper mount from a dual "leg" type to something resembling AJPS's FC caliper mount. Made the mount out of 12mm thick 2024. Decrease the 12300N to a more realistic 10,000N by reducing the 100% front weight distribution to 80/20.
The safety factor is still barely 0.55. The highest stresses are seen at the two outer bolt holes. Easily fixed by helicoiling the bolt holes. The tips of the caliper attaching bolts move 0.05592mm. Good enough?
This is all based on the assumption that the caliper mounting plate will be flat. I'll figure that out when I mock up on car.
Got some interesting results re: material, mass and strength, I'll post it up hopefully tomorrow.
I run twin spot brembos on F-series mx13 rear. R33 gtr rear disk (300x22mm) redrilled to 4x114.3 and using an internal drum handbrake. The inner of the disk had to be machined 1mm to accomodate the internal drums. The caliper bracket is flat made from 8mm thick steel.
Nice to see you're still around Eddie.
May I ask why it is that you machined the drum surface of the disc? Are you still running the original MX13 drums and machined the discs to fit? I don't see why you would machine the drum surface if you were still running R33 GT-R drum assembly.
No I'm running an rt142/st141 internal drum setup. The r33 disk is almost perfect in every way except for that one dimension. I still had to take off some pad material even after machining the i.d.
Anyone got a setup on a yr22 diff?
im doing the test fit up now with the brackets i made for the MX13 F diff.
Kaan, I've got a set up. It's just S13 caliper and disc but will allow you to bolt on R32/R33/Z32 rear caliper and disc but you lose handbrake as R/Z is internal drum. It's a pretty goofy set up but I wanna play around with the caliper and plate locations and try and get it to work without spacing stuff.
Next one I make will have R33 caliper mount as well as mounts wilwood forged superlite internal caliper mounts for R33 294x18mm disc.
