Rotor selection

Elmo370z · 01-23-2018, 12:35 AM

(2 piece)DBA's but gosh they are hella expensive for just rotors. ( 2 piece) Z1 rotors, 2(piece) stop tech. If any has an input far as other 2 piece rotors or any insight on the ones I've listed it would be greatly appreciated.

With rotors, IMHO, you get what you pay for, but there are some tricks

Before use, I cryo-treat mine which doubles rotor life when used with ultra-agressive race pads.

Rotor bedding is mandatory (manufacturer process).

Because DBA is an Australian company (that is the A in DBA) I do tend to use them but have used Brembo in the past to good effect.

I bought rotor rings and made my own hats as I have access to a mill/lathe.

Still not cheap though.

The other thing I did was use DBA 52102 rings as these are for a domestic AUS Ford Falcon GT ... and I bought off a race team who had to order a minimum quantity of 50 - they on-sold 10 pairs (I bought 2 sets) and kept the rest for their race team so it is always worth a lateral approach. I doubt Doran Racing have any 370Z bits left but for the price of a phone call, you never know.

Cold firing helps with life and the original pair has only just been swapped after 6 years of DD and maybe 10 track sessions per year.

Whatever you do, I'd strongly recommend cold-fire treatment.

PM me if you want details.

Thanks for the recommendation

Why do you want 2 Piece Rotors? Unless it's for looks or your running a striped down track car I don't see the benefit. Cost savings would be nice but a quality set of one piece rotors are cheaper then replacement disks for 2 piece. I went with Frozen Rotors blanks, they work well on the street and track and are not expensive.

I believe he is building a dedicated track car.

I'm tired of blowing through rotors. Last set only last 9,000 miles with 2 track days before they were warped. Im getting fASTER and more aggressive around the track, plus i would like the unsprung weight and and heat dissipation of a 2 piece rotor.

Get 2 piece cryo treated then.

Just ordered these this morning. Have slotted rotors right now and think they are causing excessive wear on my XP8 pads. The high carbon ones worked really good for me the first time I used them. Too bad you can't get the high carbon for the rears. (free shipping)

CENTRIC HIGH CARBON PLAIN 125 SERIES ROTOR
2 In Stock $99.00 $198.00
Note: (Front) Plain vented rotor. For sport package models.

CENTRIC PLAIN 120 SERIES ROTORS
2 In Stock $65.00 $130.00
Note: (Rear) Plain vented rotor. For sport package models.

That would be a negative on increased wear. I am at half pad on a full set of XP8's with Dragon driving and street driving for over 80k miles.

Are your running the slotted? Which ones?

I run slotted and would recommend slotted or sprinkled overe drilled. Drilled rotors tend to get stress fractures under extreme use.

Slotted and drilled. If I was doing mostly track days I would only do slotted.
