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 stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
