Hey guys, I'm after some advice and opnion's for a good brake setup for my 89 R32 GT-R. The car is need of new pads and disc's on the front so I'm after some advice for my setup, all I'm pretty much after is a good street setup, though a little bit of overkill couldn't hurt. After doing a few search's and reading all the info (took hours) here's what i've come up with.

Some info about the car that might help.

Already has braided brake lines, HSD HR Coilovers, pineapples, 18x10 Work rims (265/35/18 rubber) 230kw @ all 4.. This is my daily driver at the moment, and the pads on the car are as dusty as hell leaving crap all over the wheels which is annoying. I'd like to minimize brake dust as much as possible.

Current brake setup;

Stock Calipers

Stock 296x32 rotors

Unknon pads

Unknown fulid

After taking in the info, here's what I've come up with;

Motul RBF600 fluid

DBA4000 replacement slotted rotors

(Retaining original Calipers)

Ferado DS2500 pads

Take the dust covers off the front

Ducting to the rotors

Does thing sound like a good setup? Opinions and advice would be great. Also, I've been looking into the caliper spacer that UAS sell so I can run a larger rotor, which to me sounds like a good idea bang for buck, I'm leaning towards getting the spacer kit with the larger DBA4000 slotted rotor, would this be worth doing? I've noticed a few people running the DBA5000 two piece rotor's with spacer kit, but I'm not planning to take the car to the track so it might be a waste for normal/street driving.

Cheers, mat.

if it's for street then forget the DS2500s. endless SSS will be good for your plan. very quiet and not too dusty.

Thanks for your reply, I didnt look into the endless pads. Any advice on the spacer setup vs standard? I understand ' Caz ' on here was doing the adapters for a good price.. anyone know if he's still doing those? (Yes i've PM'd him) :)

For street, the stockers are fine. You dont need RBF600 (Dot 5.1 is half the price and should last longer), or the UAS kit (i have it and its an inelegant solution, a bit too much hacking to get it on IMO). Consider rebuilding the calipers tho to make sure they're in top shape. The kit for the front cost me $85 from Racebrakes. Rear was $40.

Likewise you dont need to worry about removing the dust covers or ducting.

Adam, What hacking was required to get the UAS kit on? I trial fitted the 343mm one on mine and the only thing you had to remove was the stone guards. Be keen to know if anything else is required as I have the kit for sale and don't want to sell someone a piece of crap.

If it is just street you are after I would recommend:

RDA rotors from the group buy section. They are much cheaper than the DBA series.

Ferodo pads, maybe not DS2500's, but a cheaper alternative. Look for something with a friction coefficient of about 0.5.

Any common or garden Dot 4 brake fluid - you don't need 600 degree stuff,

Leave the stone guards (Not dust covers!) on.

Forget about ducting.

Replace both front & rear pads.

For street, the stockers are fine. You dont need RBF600 (Dot 5.1 is half the price and should last longer), or the UAS kit (i have it and its an inelegant solution, a bit too much hacking to get it on IMO).

What chopping needs to be done? Thats partly the reason why i think the 280 to 324mm kit like mine works better then the 296 to 324mm as the adaptor is more robust/meaty.

Interested to hear what had to be done

also keen to know what u mean by "hacking"

Adam, What hacking was required to get the UAS kit on? I trial fitted the 343mm one on mine and the only thing you had to remove was the stone guards.

The 343mm kit is fine - there's enough room to make a simple bracket. The 324s have an odd shape that moves the caliper out radially as well as down tangentially to get enough room. Its cleverly designed and nicely machined, but there just not enough room to make it an easy fit.

Re: hacking, as John P will tell you, they dont just bolt on. I had to do quite a bit of angle grinder work to get them into a position that allowed them to be bolted up. The bolt holes in the bracket dont line up until you've removed material on a number of surfaces. Also, you have to bend the brake line a lot to get it to reach. If i were to make the decision today i'd go for the justjap 330mm G4 kit over the UAS 324.

In this photo you can see the bottom of the lower bolt hole on the hub has been ground to allow the bracket to fit. I had to remove more that what's in this picture, i doubt this picture shows the finished job.

also you have to be real careful with fitting of brake caliper mounts and mods!

i saw a brake mount break away and the caliper swung around and took out the lower control arm ! driver was at speed & in an instant had limited steering and loss of brakes.!!!

cheers russ

interesting, thanks heaps for your input...

bending the brake lines wont matter with me because im going to use braided lines and im fairly handy with a old angle grinder so that wouldnt bother me too much. still seems a bit dodgy that u pay decent money for something that doesnt fit properly. i would expect it from china but not a aussie workshop

or another option would be to get a 343mm kit but would there be rda rotors available at this size, or any other options other than dba?!?

but will 343mm calipers fit under 17 by 9 buddy clubs?!?

Should fit. Check the ap racing website for their template for that rotor size with the CP5555 caliper. The 6 pot CP5555 is larger than the 4 pot Nissan Brembo or the Sumitomo.

In any case you can readilly compare the caliper sizes.

But I don't know of a cheap 343 rotor....

There are a few cheapish 343 and 340mm rotors around. And you will find that even if the likes of hte AP CP5555 is bigger, it actually saddles the rotor better meaning less clearance is required over the rotor diameter.

The std rotor may fit inside a 17" wheel but it would almost have to be a GTR esque offset. Also, the pad area and swept area of the Sumitomo caliper means that the 343mm rotor is an even bigger compromise then the 324mm rotor with std caliper.

Really, in my eyes the 324mm rotor std caliper upgrade is brilliant for R32, Z32 and S13/14/15, but not quite as good for R32 GTR and R33 GTS25t etc.

It works for the 296mm rotor crowd, but you may as welljust find the pennies and either grab some GTR Brembos or flog off you 296mm setup to a silvia owner and get a Z32 or R32 caliper to run with the 324mm rotor and bracket

    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'  
    • D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
