Drilled Brake Rotors

You still need to sort out master cylinder and rear brakes with that kit. The one you want is the Goodwin brake kit.

no, brembo can supply it all. it would be exy, but would be well worth it.

back on topic though. so i shouldnt drive my car on the race track with the curent setup, or very hard for that matter? so does that mean no spirited driving?

dont go the wilwood
I have been told that all they do is upgrade the front brakes.
for the rears they just have a spacer for the calipers and put in a bigger rotor. so you get all this extra braking power at the front but pretty much exactly the same on the back.
If you are willing to wait a fewish weeks a member from the advan group (we call the place WHEELSPIN) has just made their own kit comprising of mainly RX-7 brakes which are as a matter of fact... bigger than the wilwood kits including bigger calipers and rotors for the back.
The front has 12" rotors and 4 piston calipers while the real has the same rotor i think but big single piston calipers.
PM the guy, MX52NV
the kit is his and it is still prototype at the moment but he is hoping to put it into production really really soon.
Big Up for Wheelspin!

half of the advantage of getting a quality big brake kit is for the weight saving.
why would anyone want to stick huge heavy rotors on their car & stuff up the handling by adding so much unsprung weight when you could get a quality kit like Goodwin which uses lightweight calipers & alloy centres on the rotors & is heaps lighter than the tiny little NA6 brakes.
you get much better braking & better handling because of the reduction in unsprung weight when using a quality kit.

Just to address the points raised on the weight issue.

The standard NA6CE single piston front caliper weighs 3 kg.
The FC/FD RX7 4 piston front caliper weighs 2.5 kg INCLUDING the adaptor brackets.

As mentioned, the kit is still under development - we are endeavouring to use readily available OFF THE SHELF parts.

Stay tuned for updates.

i know that.
i checked out all the popular conversions before i bought the Goodwin kit a couple of years ago.
with the RX7 conversion that guys in the US were doing all the extra weight was in the bigger rotors.
Brembo & AP have light weight parts available but trying to sort out a kit that will fit properly was a hassle & no one new if it would work properly.
Goodwin was the only company supplying a kit made just for the MX5 & the complete kit is heaps lighter than the original NA6 brakes it replaced.

I had a mate with DBA Gold Cross drilled rotors on his EB XR6 and he managed to get about 100 cracks over the pair of front rotors just thru harsh treatment on the street.

Everyone I know with slotted rotors, regardless of the car, have not had similar problems.
