without going for a big upgrade, have you guys got anything to say on drilled/grooved discs such as

or, better off with a decent brand solid disc?

 

my current discs, although not showing heaps of wear/lip, are starting to cause vibration under heavy braking at say 60-70mph and wondered if i'd be better off with vented/driled to try and prevent warping in whatever set i get next

 

opinions pliz!

My general view is that drilled discs are far more likely to crack than solid ones, probably best avoided. Discs also very, seldom actually warp, so that should not be a concern for road use.

have you checked other things like tension rod bushes?

polybushed :)

Have you checked for cracked lower arms then? Lol!

You always hear that drilled discs crack but does anyone actually have first hand experience? And if they're so bad then why does nearly every supercar have them?

Yes ... 2 sets of front discs i had Crack on me ..

 

 

but regarding better brakes ...

 

Slotted Discs with Red Stuff Pads ... loads better than stock

I have a CLK Black Edition in my workshop at the moment - the customer has come back from a couple of track days & the discs are cracked everywhere around the holes! Still, only £670+vat per disc!! :scared:

grooved discs then maybe? but not drilled. think they're about the same price anyway

yep grooved/slotted discs will be good

Interesting that I have a slight warp on my stock discs at higher speeds after couple of braking sessions and after fitting the spl tension rods with there optional brake deflector air vents 90% of the warp has disappeared so air flow is an issue to the discs

warp doesn't fix itself so sounds like you had pad deposits on the disc

no it dosent but it was only minor and with heat build up but cured the problem so as to speak
