I have been running for around 2 years a 4 lug 4 piston caliper 5 lug rotor hybrid on my car thanks 2 Aaron Cake spacers and let me tell you guys this is one of the best mods that i have done 2 my car,brakes feel awesome and stopping is great,next on the list is my ignition upgrade.I have a Microtech LT8S regular wasted spark setup running 2 MSD single tower coils on trailing firing from the stock igniter and a dual MSD coil box running from a streetfire cdi box for leading.Let me tell you starting the car now is easier(bridgeports are a pain 2 start sometimes cause plugs like 2 go bad on them)and spark is way stronger,dwell is 2.75 and coils dont get hot at all!So far so good.Next on the list is my AEM wideband,i had a LC1 unit that went bad and i did replace it with the AEM unit and i love it.Next on my list is a full suspension upgrade and a full cage for the beast.

 

And here is a pic of the test subject for those that have never seen it before.

 

Glad they are working out for you! I think I've had mine on for about 4 years now. No vibrations or weird wear. Though I do need to upgrade the master cylinder.

 

Thanks Aaron for the spacers!I am still using the 4 lug master and brake cilinder and it does seem fine,what makes you thing that you need 2 upgrade the master?

 

think your rotors are on backwards

The original S4 single piston master has a lot of travel with the bigger brakes. Plus, mine is over 10 years old so it's about that time when I'd replace it just because of age anyway. Probably go with the 626 (or is that 929?) master.

 

Now im confused cause they have a R an L stamped on them and they were installed according 2 that.Let me look at it again,thanks for letting me know buddy!

 

The outside slots are irrelevant, its the direction of the internal cooling vanes that determine left from right.

 

i only say this since i have the same rotors, this had me confused, so i had to look up how they go on the car
