DIY...Big Brake Kit for Under 2k

[ngng]

Gotta love when your rotors are bigger than the entire wheels on cars. On that note, you’re .75inches shy of having larger brake rotors than the Tesla Roadster had wheels.

i get fitting the same size rotor as OEM, for replacement purposes. fitting a larger rotor for a car that doesn't get tracked (where it makes sense) feels wasteful to me. a) it's not going to increase stopping power b) you're adding rotational mass which will actually make your car perform worse.

Looks like you didn't read original post and making a post with zero first hand knowledge.

A) Absolutely increased stopping power, it's still way better than OEM now 2 years later.
B) 2 piece rotors were lighter than OEM rotors even though they are bigger.

have done plenty of diy and off the shelf bbks in the past. no need to be so defensive. my reply was in response to the 390mm rotor, which, will be heavier than a 370mm rotor with the same 2pc rotor hat. yes, there are weigh savings from going from the cast 1 pc rotor to a 2pc setup.

oops, accidentally hit reply

as for "increased stopping power". i guess it depends what you mean by that. will give your braking system greater heat capacity, for repeated high speed stops? yes. does it make your car "brake faster" no, it won't. a sticker tire will do that.

I mean, by that theory all the P- Tesla’s are wasteful. And really any car with more than what? 300hp? Is really wasted if you don’t track it. How many people NEED to go 0-60 in under 3 seconds? And how many regularly do?

I get your point - it’s certainly one that’s well understood by me. But don’t mistake a general appreciation for the part for a lack of understanding.

haha, i'd argue > 100hp is a waste...but, this is coming from a a spec miata owner. don't get me wrong, i love modding things, if you wanna throw 390s on, by all means.

No reason for this post except my RB brakes just passed the 50 K mile mark with no problems. RB pads and fluid change work perfectly except for the occasional click now that the rotors have been worked hard a few times.

do you know RB uses standard or floating rotor harwdware?

My RB rotors came with standard hardware.

Thought I’d fill you guys in on the development!!!

I didn’t want to void my warranty by drilling out the caliper mounting holes to 14mm so we modified the calipers instead. We made inserts for the caliper to go from 14mm to 12mm. Let me know what you think.

Nice setup. Where did you get those solid (w/o slots and holes) brake rotors?

looks clean! be careful with those 2 ton stands. the S is heeeavy.

Just completed mine:

Wonder why RB changed the rotors. My front and rear rotors are drilled within the slots.

realistically? prob cost less for blanks. no reason for a street car to have drilled. greater potential for failure with drilled as well. slots have some benefits, but also increase brake wear.

I don't think RB makes rotors. I think they are buying rotors from 3rd party and makes hats for them only.

Tbh I would be happy to have blank rotors

look at the plastic fender, that is the S's heavier big brother.

in that case...be even more careful with those 2 ton stands

yum, those are lovely! you'll never have to replace your brakes again haha! ironically though, I removed the ceramic brakes from my porsche and replaced them with steel because they were too expensive to run on the track :lol:

Will your shop consider a group buy for the hats? Thanks
