Upgraded brakes for NA6

[Fatty]

you could always just upgrade the na6 rotors and pads. i got dba slotteds and bendix pads. stops better now. i've only done the front. i'm going to put na8 brakes on the back, but really the fronts do most of the work so i'm not sure if i'll see much more improvement.

As Fatty suggests, often just upgrading the pads is a big difference. Tyres would be the next thing to look at (since they're what actually stop the car).

Are you having brake problems, or just getting ideas?

If you are talking about options for the track; NA8 brakes are the cheapest upgrade. NB8A are the same (I think) but NB8B are bigger again.

Anything other than this will require brackets or a deep pocket (Wilwood Big Brake kit starts at $2k IIRC).

Upgrade pads if it's just for track days; if it's for a track car then I'd go for the NB8B kit for ~$850.

i think you missed the part where slugoid said "for cheap"

With good pads, a master cylinder brace and some braided lines, you'll have a pretty good setup.

Getting more bias to the rear of an NA6 definitely helps. You can use an aftermarket adjustable valve (Wilwood/Tilton) with the correct adaptors, or you can retrofit an NB valve (~$250) quite easily.

Matty,
The master cylinder brace what does this do, stop firewall flex? Any pics of one.

Thanks

We have just done a Skyline R32 4 spot conversion on one of our SE's. We weren't sure of the effect they would have with the ABS and only ran Bendix Advance pads front and rear but were very impressed with them. Now we will step up and put decent race pads in them for the next event. Also hope to have our second SE upgraded to them as well.

The Skyline caliper is all alloy and quite cheap to get hold of. Additionally there are numerous types of pads available for it. The RX7 caliper was an option but generally they are to expensive to obtain in any great number.

We are looking at the viability of making them available as a kit however they will only be suitable for race cars as this sort of mods on road registered cars can open up all sorts of bureaucratic head scratching......

I thought R32s were a 5 stud hub... What discs are you using?

i'm hoping that by using slotted na6 rotors on the front, and na8 brakes on the back, i'll get more rear bias and overall better performance, and brake fade will no longer be a problem.

i'm no engineer (HINT HINT MATTY - I'D BE KEEN ON YOUR OPINION ) but it makes sense to me that the rears will now have more stopping power, given the same amount of pressure applied to the pedal. hence, more rear bias. i have no data to back this up, so i'll just have to wait and see. the na8 rears are sitting in the shed ready to go, i just haven;t got around to it yet.

also bruce, i have a master cylinder brace (also sitting in the shed) if you wanna have a look at it. i got it thru one of the famous "boags group buys" a few months ago, still haven't got around to fitting it yet

NA8 upgrade isnt expensive, it is if you swallow the prices the local suppliers want though!

Got my 4 wheel upgrade (caliper brackets, new rotors, HP+ pads, stainless lines) ex USA for 550 bucks including freight (Ocean).
