Hey guys, my rotors have had their better days and are due for a change, actually that worn that they can't be machined. I have a track day coming up and don't want to risk it with those brakes flying down a straight at 200. I've read mixed reviews on all rotors, just wanted to see what everyone thought. What rotors would be recommended for slight track use but mainly a daily. Note my budget isn't the greatest !

Car is a R33 gts-t

Thanks in advance

What makes you think this thread will be any different? LOL.

Prepare for a clusterf**k of different opinions. Personally, I use RDA.

Over the years I've only used 3 types of rotors in my Riceline, OEM, RDA Slotted and Dimpled and DBA T3 Slotted. In my opinion there was very little difference in performance between the three as far as on the track went. I found that the main difference came to how glazed the rotors where at the end of the day (OEM glazed badly, RDA was better and DBA was even better than RDA) and NVH (OEM had little to no NVH, DBA had a little and RDA had the most)

If I had to do it all over again and price wasn't a consideration, I'd probably go the DBAs for no other reason than I like the look of the slot pattern. In reality I'd probably just go an OEM or OEM style because I'm tighter these days!

I think that you should move down this list depending on budget and application:

1. Two piece floating rotor (PFC, Project Mu, etc)

2. Two piece rotor (DBA5000, etc)

3. One piece rotor with uni directional vanes (DBA4000, RDA, etc)

All will be suitable for light track work.

If your budget isn't the greatest and can't buy a big brake kit. I'd buy RDA/DBA non slotted replacement rotors, good pads and fluid. Because stuff wasting money on slots that do jackall and will probably start cracking at some point and offer little to no benefit.

Yeah if you want to waste even more money buy project mu.

Waste? Have had project mu on my car for years. They cope really well to track work and don't crack like I have experienced other rotors doing. The 2 piece I have on the front of my GTR have stood up really, really well. Something I cant say for their equivalent in a DBA or an RDA. So, yeah, if waste is fixing it once, properly, then waste away. You don't need to spend big dollars on Pommie stuff.

And how much do these 2 piece project mu rotors cost.? Considering OP's intended use is a daily drive with a dream to go to the track(lightly). yes I would consider it wasted money even for their over priced OE slotted replacement vs. the RDA/DBA equivalent.

How much are you paying for your DBA rotors? And how many times do you multiply that by for replacement and/or machining?

Not all PMu rotors are two piece they have a number of different one piece options.

Anyway there is an option there. How cheap or how hard he uses them is up to him.

I dont think project mu's rotors are invinciable or made a highly secret way. you will have to replace them too, Like every other brake rotor. And may of may not add any benefit to braking or last any longer then the RDA rotor which is 1/3rd the cost.

      Much less twat-tastic. CF wheels are too garish for civilised use.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
