Hey folks have questions regarding the ROTORS [X5 '05 4.4i sport]:
F rotors current thickness is - 31mm [the minimum thickness stamped on the F rotors is 28.4mm] difference of 2.6mm.
R rotors current thickness is -20mm [ the minimum thickness stamped on the R rotors is 18.4mm] difference of 1.6mm.
1. Does anyone know the thickness on brand new oem rotors F/ R ?
2. I'm about to change ALL F/R pads - should I change ALL Rotors at that same time, does the above thikness of 2.6mm F and 1.6 mm R is enough to be left for new pairs of F/R brake pads ?
3. How many miles this rotors thickness of 2.6mm F & 1.6mm R down to the minimum will last ...... [ just a wild guess] ? ---- [ sure it all depends from the driving style and so on other factors but still on average .... is it for example 1k or 10k miles ]
4. Currently my X5 does have 70.000 miles any opinions if that are the original rotors or it is on the second, 3rd pairs ?
5. when installing the Rear rotors do they SLIDE over the Ebrake pads with no problems or you will need some tools to fit that E-brake pads ? --- [ or if the Ebrake is NOT applied then it's all ok to install R rotors with no problems].
6. any opinions on drilled or/and slotted rotors on the X5 ? ---- [ they are pretty much the same price as the none drilled non oem rotors ..... so I'm wondering if I should go for drilled ones...[for the look/ performance]] ...
Thanks in advance
