R33 Rda Slotted Rotors

[08r3308]

i just wanted to see how are you guys going with your rotors , i guess everyone had them bed in by now

what pads are best for these?

anybody run them on track cars?

how did everyone go with orientation of rotors , i know there's left and right on boxes but would this link be right way to do it?

if anyone has pictures please do post

cheers

i can check the orientation when i get home if you want, i have ran Endless SSS and Racebrakes RB74 with mine, prefer the RB74 (I have used many pads, but only those two on RDA slotted rotors)

I love the rotors. Well worth the money. Just running stock pads at the moment and it pulls up much better after a bit of work. No fade and better feel.

Orientation of RDA slotted rotors makes absolutely no difference what so ever as their internal veins are straight...

that explains it , i followed the markings on rda's box and they appear to be same way as on dba site so i guess there's no wrong or right way to put them on.

btw im using qfm HP-X that i got from GLS Rallysport and they are great so far (still bedding in rotors so babying it for another 150km or so)

The only time rotors can be on right or wrong is when the internal veins are directional, in which case it's VERY important they're on the right way!!!

DBA, RDA and most other cheap brands might specify a direction on the box, but it will make 3/8 SFA difference because the internal veins are straight.

Ironically enough, most of the big end of town rotors (Brembo, AP etc.) which do have directional internal veins, will actually have the external slots the opposite of what DBA and RDA specify...

r33 rda's on the front and rear here

heaps of track work (7'ish days)

3 sets of trw on the front

1 set of qfm on the front

close enough to no wear on the rotor (though they have surface marking)

2 sets of trw on the rear

1 set of qfm on the rear

close enough to no wear

qfm are worth the extra $$ over the trw. trw were good but has all the bite at the end of the pedal and in the last 50m, and faded after 3 laps.

qfm has better initial bite and don't fade, they feel harder if you know wat i mean.

there wasnt enough brakes for me. uas caliper spacers and 324mm dba rotors now. testing this weekend.

same set of qfm's and rda rotors on the rear and onto second set of qfms now with some air ducting on the front.

thank you for that john , keep them coming guys

Also keep in mind guys that there are compounds above A1RM in the QFM range, but these do start to become track only pads. Comp 6,7,8,9,12,15 etc...

Do you have more info on these? It might be worth advertising them on here...

Just thought I'd throw this out there, I run Ferodo DS2500 pads and find them a good compromise of street/track but they're not cheap

yeh over double the price of qfm

[08r3308]

i found my qfm are pretty good so far will see how i go

I ran a set of Hawk Blue Track pads at the last Oran Park Day. They worked great but did put a very slight lip on my brand new rotors - I think any serious track pad would. Lots o stopping power there. I couldn't believe how solid the pedal feel was with this combo - totally different feel to a stock pad.

Now I have EBC Reds in (the ones I glazed at Wakefield Park after a 12 minute session). They don't have much initial bite now, but pull up ok at the bottom of the pedal - but the feel is so much squishy-er than the Hawks.

Oh, and the Hawk/RDA combo went a full 15 minute session with 0 fade.

I have rda on my 33, i would reccommend dba due to the fact that they paint the non pad surface area, all rdas will rust in this area and dont look the best from close up

Only other difference is that rda slots go all the way to the end of the rotor, where dba slots stop short of the end of the rotor, not very significant in my opinion

^ Paint the rotor before you put it on?
