ebay brake discs, any good???

[chrisJDM]

ive been looking around for some new brake discs and found a good price on ebay for all four.  They look ok and are only grooved and not drilled which i prefer, anyone else purchased them???

Also in the ebay ad it says:
"THESE DISCS are HIGH QUALITY and CAN BE ZINC PLATED SILVER ,GOLD or BLACK PHOSPHATE TO PREVENT RUST..at £19.99 (For the 4)."

is this worth doing?

i have a set and they are good

just make sure you give the bells a bit of silver / black hammerite before you put them on or get him to coat em (think he charges a bit extra for that) and do the obvious - like get all the oily stuff off them, and bed them in etc.

[chrisJDM]

cool cheers, did you get the zinc coating done on yours?

They are probably blue print oem ones that have had grooves machined in. I wouldn\'t expect any real performance improvment.

[chrisJDM]

well my current discs came on the car, ive had it 3 years, they are grooved disks but im not sure which make, where would it usually say on them???  Im changing the pads and doing a fluid change so thought i might do the discs aswell as im not sure what condition the current ones are in.

i bought the fronts only for £100 i think. cheaper than stock items LOL. this guy makes disks for all sorts of cars and no one i know round here who has these has had a problem with them.

ok - i know they are very cheap. they arnt stock items as they come in a yellow box that doesnt have blueprint written on them (i cant remember the make sorry)

anyway as a measure of performance -- i managed to lock the front wheels at 90mph before abs kicked in - during an emergency manouvre (sp) on the motorway, (nob head in a mondeo decided to cut me up then gives me the finger as i go past!!!) anyway my point is they do work lots better then the stock ones i had, good feel nice bite but controllable, trust me its a mucho improvement not had them fade on me either.

I didnt get the zinc coating done - no - lol, now i have to hammerite them cos they all brown rusty colour but i have some silver hammerite and when i get round to it they will look like new again!

Im looking at getting some decent brakes too. I was looking at these http://www.turboimport.com/catalog/rx7.htm but dont want the dimples as they are prone to cracking and he wants a fortune to post them over here.

[chrisJDM]

wot i might do is take of my current ones and get them tested and see if they are ok, if they are warped or badly worn will get some new ones.

[RobbieRX-7]

do that yourself. If there is a deep lip on the edge of the disk or any ripples on the surface of the disk they are worn. To test if they are warped just find a long downhill where you can get a good 80mph. press the brakes hard and If the wheel starts to shake, they are warped, or use a dial test indicator with magnetic base on each disk

[chrisJDM]

cool sounds good i will take a look at them and give that a go cheers
