For the sake of disseminating information, I will comment on the RR Racing sport performance (4 pot) front BBK because I bought one.
When I first got the kit (a few weeks ago now) I measured the pistons and recall they were ~38mm based on my eye and a crappy school book ruler. The rest of the relevant info is available on their website so I stuck the values in a torque calculator and came out with a slightly higher torque value with the RR Racing front kit than stock. I did this a while ago so I don't remember the exact values but my point was that Rafi mentioned this was the case so I can confirm he never said anything misleading or incorrect.
I realize it seems the real issue CSG and JRitt have is the claim that increasing rear bias is beneficial when their own findings indicated that wasn't the case and are looking for data from RR Racing to back their claim up. I'm not going to lie here, I DO think the rear kits are primarily superficial especially for cars with no rear downforce so I have no plans on getting one.
In the end, I'm of the opinion that AP's caliper and rotors are the best so if you want the best, you need to pay the extra to go with AP. In my case, I'd love to get an AP kit but the reality is that I cannot pay for it now or in the forseeable future. If an affordable alternative never appeared, I'd never be able to upgrade. Suggesting that I save up for it isn't helpful because I'm also saving for a house and every dollar spent on something else is a dollar that doesn't go into the house. This is why I look for products that are 70% of the high end product for 50% of the cost and RR Racing has released an offering that appears to be in this range, targeting people like me. |
Actually, that would be the AP. Ironically the math is almost perfect, in my example below, using crude calculations
My kit of choice is a Brembo front, but that costs $3895 retail. The AP Sprint is $2099 retail, and gets the job done just as well for 90% of the people out there. For those running full slicks, and/or are boosted and/or want the best and/or will only run forged wheels, the Brembo *is* the superior product.
The AP is, hands down, the best bang for the buck (especially when you consider longevity and the cost of upkeep with heavy duty use), and that's why the CSG car runs the Essex AP kit. The cost is brought down by using a genuine racing product, that is acceptable for street use in a variety (but not all) conditions. Because there is no fancy paint (which burns off), dust boots that will burn off under hard use anyways, and a lot of common components (e.g. pads), the cost is brought down, while maintaining top notch quality.
