FC Rear Caliper Differences
 

Hey guys. I'm swapping to Turbo brakes on my SE and following Aaroncake's install on his website. I got a killer deal on a set of 4 Turbo rotors so I'm wondering if they will work in place of my non vented rears and if there is difference in calipers. I just replaced my rear calipers like 3,000 miles ago so don't want to have to again but would love these rotors since they are slotted ( and dare I say....drilled.....). Tried doing a little searching but couldn't really find my answer and can't try it out until like next weekend so I'm trying to get it figured out before i dive in since it is my daily. Thanks!!

Calipers are different for vented to non-vented rotors.

If you have 4 lug fronts and rears the T2 rotors will not fit. If you have 5 lug then the rotors will fit but you should have changed out calipers at that time for both the front and rear if you had 4 lug to start with.

I have 4 lug hubs. I re drilled the rotors using one of the milling machines I have access to here at school and also am in the process of machining the spacers to space out the front rotors and bought 4 piston, Turbo II front calipers. So I am converting EVERYTHING to the bigger Turbo II brakes and they will fit. I was just wondering about the rear calipers because no matter where I look, they just say " Rear calipers" but nothing about for vented on non vented rotors. That's why I wasn't sure. What exact models had the vented rear rotors?

The rear calipers are different between the 4 lug design and 5 lug design. You most likely will need to modify the caliper mounts to use the 4 lug caliper with a 5 lug rotr.

s4: convertible and TII
s5: convertible, TII, GTUS

There may be a few other models, that's the ones I definitely know.

This is what I'm looking for. Thank you!!!!
