Yewhiong Neutral Newbie January 12, 2009 Share January 12, 2009 Hi Bros, I am due to change my brake rotors. Based on the same dimension of the brake rotors, which is lighter - slotted or stock (solid) ? Please enlighten me.

Please enlighten me. Regards, Kent Honestly, there's not going to be much difference.... If you're going to slot the stock rotors, you're only shaving off very little metal that isn't going to reduce weight that much :) It's more for aesthetics purpose only if you ask me...you want better performance, you need a larger rotor and calipers.

Based on the same dimension of the brake rotors, which is lighter - slotted or stock (solid) ? Please enlighten me. Regards, Kent Stick to stock rotors but you can choose other brand. Cross-drilled rotors are actually weaker and the slots will increase wear to your brake pads. It will also cause noise. Link to post Share on other sites More sharing options...

Please enlighten me. Regards, Kent If you want better braking power without spending alot, the best to get a bigger size rotor. Bigger rotor dissipate heat better/faster and aid in braking.

Dwoon 1st Gear January 15, 2009 Share January 15, 2009 Bigger rotors using the same calipers will require a customised bracket to mount the calipers further out. I've heard of people doing this... but is it advisable? Also, the wheels need to clear the bigger rotors/new caliper positioning .....

Some stock calipers can take in bigger dimentsion without modificaton. In my previous car, I changed the calipers from a higher model of the same made to accomodate a larger rotor. Still alot cheaper than going for aftermarket calipers. Regards, Link to post Share on other sites More sharing options...
A_korusawa 5th Gear January 15, 2009 Share January 15, 2009 (edited) Well, its best you replaced the brake hose with teflon & stainless steel types. Its a 'must' before you do anythings to your rotors. Also, make sure that the hose is teflon & stainless steel type, eg. goodridge etc. You may wanna save cost by slotting on your original rotors. OEM stock can be slotted but NOT drill thru' holes!!! This is b'cos stock rotor is casted and stress fractures may result from drilled throughs. Replacements of rotors will only be worthwhile if you are going for bigger ones, and that means changes to calipers and brackets are unavoidable. Another way to increase your braking is to fabricate a brake stopper. Its for minimizing the gap tolerance 'flab' by the brake pump. Last but not least, replacing the brake pump. The above are listed in sequence.......hope this helps! Cheers Edited January 15, 2009 by A_korusawa Link to post Share on other sites More sharing options...

BMW320i Neutral Newbie January 16, 2009 Share January 16, 2009 If you want better braking power without spending alot, the best to get a bigger size rotor. Bigger rotor dissipate heat better/faster and aid in braking. Regards, It doesn't aid braking but rather it aids endurance. The gains from larger rotors as mentioned in other threads I have posted before but people are too lazy to search and read is because pad contact with rotors is applied further away from hub centric.

The above are listed in sequence.......hope this helps! Cheers What you just mentioned is improving better braking "feel". Braking "feel" cannot be translated in to "actual increase" in brake performance. eg. reduced braking distance. If the rotors are unable to sustain heat, you can insert titanium braided hose/stopper and that won't benefit you in any way. If the original thread starter need to change his rotors due to wear and tear, the answer is slotted rotors. Slotted rotors will help reduce uneven pad wear. However it does not necessarily translate to improved braking performance due to the same compound nature as factory rotors. Lighter rotors, 2 piece rotors (non strap types), harder compound, larger rotors helps. If you haven't already change your pads to higher temp ones, now is a good time so that the new pads can wear into the new rotors. Link to post Share on other sites More sharing options...
BMW320i Neutral Newbie January 16, 2009 Share January 16, 2009 best is change the whole brake kit...... Changing the whole brake kit does not necessarily improve brake performance if the user have poor braking technique. You can buy 2000 pistons and 1000mm rotors but if you don't know the fundamentals of braking technique, your braking distance will be longer than what a factory can yield. I've already seen factory calipers beat 6 pistons, 8 pistons over and over again at the track simply because those people are stubborn, throw on the biggest that money can buy but don't know how to use them. ↡ Advertisement Link to post Share on other sites More sharing options...
