Looking at some new front discs for a non-Brembo R32 GT-R as the oldies are starting to squeal constantly and RDA seem to be the cheapest decent discs around for a decent price. What i'd like to know is if there is going to be a big enough difference in performance between their plain discs and their basic slotted drilled discs to justify spending around twice the price? It's only due to still having the original nissan calipers that we're looking for a cheap 'band-aid' solution to last a couple of months.

seems you need to decide if you want cheap band-aid fix or something decent...

have been told the RDA dimple ones are a good way to go.

Yeah, not got the funds for better discs, but bigger brakes are already high on the list of needs so it's only going to be temporary hopefully. I suppose everyone here goes GSLRallysport for their RDA+QFM setups? Any one maybe in Sydney or Newcastle or in between?

Plain discs (Not slotted, drilled or dimpled) work fine on road cars. So just get some of them and save your money.

Just rang GSL Rallysport and Brakes direct, both same prices and said plain discs are actually more than the slotted ones. Shipping will be a bit more from GSL probably but i'd rather go with an SAU advertised dealer than anyone else and especially over the guy on Ebay with some hilarious feedback. I think i'll ring GSL back and see what they can do for postage on them, cheers for the advice so far.

Slotted rotors work, I reckon the pad bite is unreal.

However no, I don't appreciate the price difference.

I buy standard rotors for 70-90 bucks a pair and send them to a CNC machinist friend who slots all my new rotors for a quick cash job. I generally end up at least 50 bucks and sometimes well over 100 bucks ahead of buying them from RDA/DBA etc

All that needs to happen is to set out an inner radius of pad area, an outer, and to make some arcs any slight radius rouhgly 6 times over the rotor. Then flip over... An easy task for any CNC machinist who knows what they're doing with a bullnose bit.

Alternatively, I reckon the Sumitomo calipers are more than enough for a Skyline... Just a decent set of pads and standard rotors should do.

if you honestly want a cheap band-aid fix for only a few months, try ebay rotors.... mine havent fallen apart yet :ph34r:

Was going to until I read some guy actually got a used machined disc in his set which put me off instantly, like how bad do you have to be. Rang GSL Rallysport back and ordered the RDA front discs and a set of the QFM HPX pads. Told him I found him through SAU too which he seem pleased to hear. :3some:

Greg at GSL said RDA had updated their range and they were some dark anodised style dimpled discs so i'm keen to see how they look aswell. All I can say is thanks for the help guys and a big thanks to Greg at GSL for being very helpful over the phone and organising it all promptly, cheers mate. :action-smiley-069:

Why have you got big brake upgrade high on your list?

Do you take your car on the track a lot?

The stock brakes are highly effective for quite a while if you upgrade the pads and rotors before you need to go spendkng thousands on bigger brakes

With a few simple mods the car can be pushed easily to 350kw, with internals its 400, but yes the car will see plenty of track time once it is reliable enough not to break parts. The pads arrived on Friday, discs today. I really hope they get rid of the soft, spongey, very un-nerving feeling the car has had since purchase..

Look at adjusting the brake peddle up.

Similar problem on my 32GTR (ABS).

I have replaced everything with new to get rid of this - Discs, pads, callipers, braided lines, BMC upgrade, Booster. Bled 5 times with new Motul 600bf (by 3 different JDM Import shops).

About to replace new Ultimate pads with new Project MU HC+ pads (not cheap) any of this.

Note: ABS DOES NEED BLEEDING.

I'm fairly certain now that I need to adjust peddle to where I feel comfortable/confident.

I should have done this first :/ (plus it should have been suggested by said "experts").

    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
    • Bloody apprentices! 🙄
    • Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
