Worth The Price Hike?

[K4L4M1TY]

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.

decent set of pads and some slotted or dimpled rotors would be nice increase in breaking over the standard getup

Slotted rotors are a marketing ploy to sell more pads.

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.

I've read this, but can you prove it either way? Genuinely curious

A 300kw road car?

Many people report reduced pad life with slotted rotors. It makes a lot of sense. Lots of nice sharp edges continually "cleaning" the pad = a planing machine.

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.

[Missileman]

gs rallysport and brakes direct are the same company i thought????

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

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.

Plain rotors, HPX pads, full flush with fresh fluid (Super DOT4 minimum), you'll be sweet.

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.

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.

They seem to have an incredibly good cost to performance ratio.

Do you know what materials they use in these pads?

[niZmO_Man]

No idea, would have to ask QFM. They don't munch discs either, my R31 ones have been going great for two years now. I might even take it to the track next month.

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").
