OK, I need new brake pads and rotors all around for my 50i.
I dont need brembo or anything fancy but Id like sloted and vented discs. Recommendations? Since Im running 18" rims for winter any discs would need to work with that. Ive reviewed all threads that I can find but I still have questions |

Since I'm unsure if you're aware, and others may not be, I'll explain rotors for all to read. A lot of folks think vented rotors means they have the drilled holes and this is incorrect. Vented means they have fins in between each disc that help expel heat from the center. I always opt for vented rotors, and most of your slotted or drilled rotors will be vented unless you're going cheap. Slotted rotors have grooves in the disc, drilled have holes through the disc. When you brake and your pads heat up they release gas, that gas stays trapped between the pad and the disc. Slots and holes are designed to allow gasses to escape from between the pad and the disc and allow more consistent bite. Now, for a street driven vehicle I will always recommend; blanks > slotted > drilled Yes, slotted and drilled rotors look better, so if you're going for aesthetics then go for slotted, but know that on a street driven vehicle you will see a higher price tag and marginal performance increase over blanks. On a track driven or "spirited" street vehicle I recommend slotted. This is where you'll start to see increased performance because you're braking harder and generating more heat and gas in your brakes. Drilled rotors are a gamble and depend in the design. Most consumer market drilled rotors are a no-go and are prone to cracking between the holes. They have too many holes that too closely spaced, too close to the edge of the disc, and not enough chamfer to prevent cracking. I witnessed a Supra grenade their brakes because of cracks between the holes of their drilled rotors. I then checked mine and noticed cracks starting and promptly replaced them. I don't recommend drilled rotors until you are talking expensive, properly engineered, race car rotors. If you're not upgrading your calipers then you don't need to worry about a rotor being too large for your wheels. You can only fit the OEM size rotor with OEM calipers. Search for rotors for your vehicle application and you'll be fine. Rotors themselves aren't that complicated and performance brands have started turning their own, so as long as you're not buying the cheap Chinese knockoffs you're likely fine. Stop-tech was always my go-to for 4 wheels, EBC for two wheels. Pads is where you'll get your moneys worth. Issue is, if you want stopping power and bite, you'll sacrifice long life and have more dust, if you want long life and less dust you'll sacrifice stopping power and bite. Honestly for a street driven vehicle any pad from your local auto parts store is plenty. If you want performance then stick with the known braking companies like Brembo, Stop-tech, EBC, etc.
