Hey dudes (and dudettes!)
I mentioned this in a different post some time ago, but I don't think it was quite the right thread.
I've got slotted and dimpled rotors on my VR-4 - made by Znoelli... probably not the best brand in the world, but it was what was recommended by a local garage, and well, they look sweeeet. :thumbsup:
http://www.znoelli.co.nz/Discs_Sport.htm Mine are the DDS ones.
Since I had them fitted I'm noticing a 'ticking' sound coming from the wheels - it's especially noticeable when passing parked cars or along side a barrier where the noise is reflected back to me.
Does anyone else with slotted/driller rotors have the same thing..?
I had a talk to the dude at Ralliart at my last service and he said they shouldn't make a noise - and he deals with slotted rotors all the time in rally cars. (He even said they might be installed backwards and they the slots should 'sweep' forwards, rather than backwards, but I've don't know if I can question the competency of the garage I went to THAT much) Also, Freddy has the same rotors up front and said he hadn't noticed a noise either.
It seems feasible to me that noise could be produced from the quick compression and release of air in the slots and dimples as they pass in and out from behind the pad - like if you pass your finger back and forth in front of your mouth while blowing, but a) the fronts seem to be worse (or at least different) from the rears, and b) the noise is getting worse :embarasse
So... any comments would be appreciated. Thanks.
