i might just get the engineering firm behind us to put grooves in the std discs. they've got a new cnc machine they're itching to play with so... :P

i ran a set of rotor's on my honda accord and after about 3000 miles they cracked thought in 2 places on each disk.......

hehe, already quoted you on that mate from another post ;)

yes shuan, i had them. they were miss - alined, gave bad vibration when at speed, they look different, the part some may say, they stopped ok & gave me good service, again, apart from being drilled wrong, so they sat wrong at the hub. i got vibration from normal driving. i woudnt look at drilled to be fair, its a starting point for cracks & stresses. just groved & vented are best.
