Hi All,

First time in the Suspension, braking and tyres section - no doubt the last time.

I want to upgrade the brakes on my R33 GTS-t and have been doing a little research on options.

The car will be used for street and track - hopefully more track, depending on my ability... he he

So the options are:

* DBA Slotted Rotors, quality pads - braided lines (legal ones) - Least cost option

* As above but GTR Bremblo Calipers on the front (source second hand) - Med $$$

* AP Racing or Wilwood - This option is the whole nine yards - big $$$

So - which is the best value (not lowest cost , I already know that) - which one will stop me better for the best $$ ?

Depending on wheel size i would suggest you get the biggest best quality rotors to go with the braided lines, pads, and fluid.

The std caliper is good enough not to justify replacement. 4 good size pistons, decent size pads and you already have them.

Some 330mm (approx, fits in 17" rim) DBA 5000 series rotors are what i wish i had of got in hindsight. I have 330 x 30mm one piece slotted rotors that are a rough equivelant to DBA 4000.

If you find you dont have enough brakes once you have the bigger/better rotors (i would be very surprised) then you can always then upgrade to aftermarket calipers.

I have seen plenty of quick Skylines at tracks using std calipers, especially GTSTs

And one more thing, my experience is the improvement in braking is more in feel and consistancy, not outright stopping distances. The car may wash off speed a little better, but it will definitely do it lap after lap with more pedal feel.

After my brake upgrade a friend was surpirsed that the car didnt stop noticably better (he was in the passenger seat at Eastren Creek) but if only he was drivng.

My thoughts are to reduce stopping distances you have to look at tyres used & suspension setup, calipers/discs wont do it alone, but a disc upgrade will give you fade free fun at the track.

I'd go with something better than DBA for the likes of you Brendan.

Something like Apex rotors with cast in slots (not the machined slots like on DBA rotors). I'd stay away from drilled rotors.

Good pads like the Endless NA series + a brake cyl. master brace and MAYBE some new braided lines.

T.

Try the rotors/pads/lines first, they should be good unless you have a very powerfull car. The new DBA 4000 series rotors are very good, much lighter than the older ones, and work well.

If you wont more i suggest looking at CSC, ther were advertised in HPI a few months ago, the price is just over 2k for a set of large 4 piston calipers with 2 piece discs, 343x32 from memorey, this is only a little more than a gtr brembro setup and is much better and all new.

Brendan, the GT-R upgrade may be the one to go for using the following formula:

bang for buck/hard road use*, where *=no. of track days

otherwise, the DBA 4000s with Ferodo DS2500 or Pagid pads (as recommended by DBA) and good quality and condition brake fluid and braided lines may be fine.

I tend to agree with Roy, consistency is as important as outright stopping power.

Agree with you Roy & Dino - What I should have said was " which one will stop me most consistantly on the track - for the best $$ ?"

I seriously doubt that I will be driving as hard on the road to warrant a brake upgrade over the standards R33 brakes - So I suppose after thinking about this, it is all about the track !

Cheers for the help peeps.

What about these

Something like Apex rotors with cast in slots (not the machined slots like on DBA rotors). I'd stay away from drilled rotors.

I can almost guarantee that if your referring to the slots in the face of the rotors, then the Apexi discs have been machined as well.

You dont get that sort of finish from a casting woithout a lot of machining

Roy - I think those DBA 5000 Series are for GTR so would need Bremblo calipers to go with them.

I've seen GRT Rotors and Bremblo Calibers for sale on this forum for about $1600.

DBA 4000 upgrade will be about $1000 minus 15% members discount (w00t)

Brainded Lines $550 (with members discount - double w00t)

So Option 1 = ~ $1450 pus pads

Option 2 = ~ $2200

Option 3 = well over $3500 I'd say.

Hmmm if I get the Bremblo's I could put the 4 pot GTS-t calipers & rotors on the Gloria ! Hmmmmmm

Don't forget B-man, as you get more power, braking power required increases by far as well. And it sounds like you'll have a fair few extra ponies ;)

Another factor is quality of your tyres, the better they are the less you need to brake as you can take the corners faster in the first place.

Third factor really is the number of full on laps you'll do at one time. I go a bit over the top sometimes, if you give the brakes a lap to cool down after every 5 its much easier on them.

I'd be taking option B, you can always trade them back in again and upgrade if you're still having problems...

Roy - I think those DBA 5000 Series are for GTR so would need Bremblo calipers to go with them.

If you are going to be opting for using larger rotors then an adaptor must be used with the std caliper to allow for the increase in rotor diam. Basically offsets the caiper mount.

The R33GTR/GTST & R32 GTSt all used 30mm thick rotors std, so the R33 caliper wont have any trouble running the DBA R33 GTR rotor which is also 30mm thick.

Im guessing but havent looked that the DBA rotor for the R33GTST is around the 296mm diam as DBA rotors are typically bolt on replacements, and a change in diameter means they aint no bolt on proposition. So if you want a bigger rotor, you have to run GTR re-placement rotors.

The reason i like the 5000 series over 4000 series, is they are lighter & dissipate heat better. The added bonus they look horn behind the wheels.

ha ha - thanks for pointing that out - goes to show you how much I know about brakes - Lucky for me there are ppl in this forum that know more than me about stuff.

Cheers,

PS Don't you think Bremblo sounds better then Brembo

Cheers,

Brendo :(

Simonster, I tried greenstuff and was *very* unhappy. They are great for dust, but they fade horribly under hard use. Not what I expected at all. Bendix Ultimate are half the price and fade much less, dusty as hell tho :D

I have found the Bendix Ultimates (F&R) pretty good so far with the 4000series DBA rotors (F&R). They withstand the 7 lap sprints around Queensland Raceway no problem, and they are cheap. Which is why I got them, I had run out of money with the other mods, but they are the single dustiest pad I have ever used. Have to clean the wheels every week now, and I only do about 200-300km a week. And my wheel are not the easiest to clean!

I would try quality slotted rotors, braided lines, quality fluid, GOOD pads, and master cyl brace first. brembo callipers as well if you can just throw them on.

track quality pads/rotors/fluid make a big difference when compared to normal or standard items.

  • 7 months later...

Reviving this thread from the dead after I got brake fade (at wakefield) on my Std brakes with SBS pads. Was scary stuff in my car.

UAS are working on a high quality adaptor for std calipers that will allow me to run the DBA 5000 slotted rotors. Now that seems like a good first step. The rotors are re-usable with the Brembos or AP Racing calipers in the future if needed.

So if I go the rotors, braided lines and good pads - I can see how that goes - if I need more, I can take the next step.

My question is - Since the DBA5000s are larger than the standard rotors, will the standard calipers/pad have enough surface area for the larger rotors ?? I understand that mounting the calipers with the adaptor will mean the everything fits - but will the pads miss out on some nice juicy rotor ?? (Means if I put larger rotors on later, the rotors will have worn uneavenly maybe ????)

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
