anyone running this ?

 

Are you doing this for performance or looks?

Here's a thread with a few users installing (https://www.s2ki.com/forums/s2000-br...lipers-1182574). When I was researching BBK's I saw some users having issues with their front pads not being aligned correctly in the Ballade kit.

This kit does not address the performance issue that people have with the rears. The Urge vented rotor kit is the most OEM solution for performance. Sakebomb or Reilly garage makes a kit using an RX-8 caliper and Mustang rotor if you need more rear braking bias and/or heat capacity. I would not trust the Ballade kit on track. If it's just for looks on the street, it'll probably be alright. That's also not getting into the drama with Ballade as a company. I'm trying not to be biased but there is no effing way I'd run this kit.

BBK's for actual track use take research and design. This kit does not appear to be heavy on either of those. Upsized non-vented rotor and hardware to move the caliper out. It is a thoughtless kit to put a product on a shelf $$$. I recently bought a BBK for my car and thought Sakebomb had the most complete offerings to address front and rear as a matched pair. Also, since Stoptech prices increased dramatically, I don't think they're the obvious choice any longer. I think the best budget setup that truly increases capacity front and rear is Sakebomb's Wilwood front matched with the RX-8 rear.

 

thanks for the info , i will just pass on these then.

 

A larger diameter rotor will increase brake torque. Same hydraulic pressure, more braking force. In other words, press pedal as hard as before, you'll have more braking force at the rear.

This will throw off braking balance, unless you equally increase brake torque at the front (using an equally, by percentage, larger front rotor, or a caliper with total larger surface area, or some carefully calculated combination of the two).

Worse, you won't actually solve anything, other than looks. You'll have ever so slightly more heat capacity, but since not vented, it won't shed heat any faster.

The slightly higher heat capacity means it'll last slightly longer on track before overheating. But once overheated it'll actually take longer than stock to cool back down (more heat to shed, but no additional heat shedding ability).

This is why the vented optio make so much sense.

Urge vented rear adds significant heat shedding capability, without altering brake balance at all. Also lighter than stock.

SBG and Reilly add even more heat shedding ability, more heat capacity, and cheaper, though add weight vs stock. If you don't need this added capacity, you're adding weight for no benefit (although cheaper is a reasonable benefit).

The best brakes are just large enough, and no larger.

 

thank you , about to order the urge rotors . thanks

 

FYI on the urge rear rotors - concept is great, but I think that the required shaving down of the brake pads reduces the benefits quite a bit.

Brake pad life and wear rate is not linear relative to pad thickness. A brake pad starting at 20mm thickness has less than 50% life left at 10mm of thickness. This is due to thermal capacity and accelerated wear rates once a threshold temperature has been reached. Thinner pad material comes up to temperature much faster than the cooling can keep up with it.

My thoughts are to go with the RX-8 upgrade over the Urge upgrade.

I've gone from Stock to Urge to RX-8 to C42. The last upgrade from RX-8 to C42 was because I wanted true BBK bling in the back to match my fronts - also decided that I was willing to ditch my e-brake in the process.

 

thanks for the info. i had already ordered the urge rotors before seeing your reply . i dont track the car as hard as some on here , so i was hoping they would be good enough for me. i can maybe hold up 3 laps before i start to lose focus.
