Warping isn't so much an issue because the MPS I'm pretty sure runs a sliding caliper anyway. What's more important in not ruining the pad is that it's bed in properly, and that the disc doesn't have any DTV (disc thickness variation).
Not critical but always recommended to change or machine rotors where possible.

http://nissansilvia.com/forums/index...post&p=5383135I used these pads on my S14... held up well! Similar in pad feel to Ferrodo DS2500s but without the hefty price tag![]()

Guys, I would recommend these. I threw a set on the other day before our Fish n Chips cruise and was very impressed with the initial bite and feel, they are definitely on par with the stock items - and so far have noticed less dust buildup too![]()
Thanks mate. From cold they definitely still hold all the properties of a normal street pad, but it's on the track or through the hills where they're in their element!![]()

Oh believe me, they got a good flogging that day![]()
So did the RT615s - im in love
I wanted to make the point about cold bite in relation to the stockers because I know quite a few people who have been disappointed with the Hawk pads in this regard which are a popular choice.

So good initial bite hey? i think i will be buying some. you had the HAWK pads too didnt you jmac? initial bite over them is noticeable?

Hi Tone,
Nah I skipped them after reading some negative comments.
The plan is to get DBA 4000 slotted rotors next (When required).
To be honest I have not noticed any difference over the normal pads in initial bite, if anything its better.
Hard on they are great!

Yeah I think i might get some of these. and stick the HAWKS on the back.
Pay day monday. There will be an order then.
thanks for the info JMAC daddy
More positive feedback from HPX users!
OzVR4HPX Pads received Greg- fantastic delivery speed!!
Bedded them in last night and i can say i'm VERY impressed. They have more bight and better co efficient than the RB74's i was previously using with better pedal modulation.

Hi Greg,
I have to say the longer they are on the better they feel.
I am now preferring these vastly over the stock pads, and I have to admit my rotors were not machined either.
For that price im not going to bother even looking at the OEM items anymore, for initial bite and feel these win hands down.
Cheers
Justin
