Worth The Price Hike?

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").

      I hope it's actually possible. This is a write off in insurance world.

      Yup. 2-way with shallow ramp angles. Still works.

      Duncan's V37.......race car?

      By Duncan · Posted

      That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      By CRSKmD · Posted

      I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain.

      OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
