I have a base (non brembo) 05 and was looking to buy some better rotors and came across Centric. They look good, have good reviews and are at a good price plus I heard stop-tech bought them. Anyways the back rotors are pretty much standard size but at the front they have different measurements. I know the non brembos have 11.65'(295.9mm) and 0.95'(24.13mm), but bigger rotors will mean better heat exchange. They have these sizes: 12.6'(320mm) x 1.024'(26mm); 12.68'(322mm) x 1.031'(26.2mm) and 12.74'(324mm) x 1.118'(28.4mm). My question is if I do get a bigger rotor will the stock caliper grab less or more area? I am assuming less because the caliper is small but i would like to hear your opinions. Thnx in advance

PS: Sorry for the long write up; don't flame me

 

kinda confused by all those numbers, but brakes are a science that comes down to millimeters. If you increase your rotor diameter by 24.1mm (about an inch, one inch = 25.4mm), they aren't going to fit without bigger brackets and whatnot to move the caliper. I think....someone correct me if I'm wrong

 

The 12.6 inch front rotors are for the 06 to 08 non Brembo cars, and the 12.7 rotors are for Brembo cars. You need to keep looking for your proper size rotors.

 

Normally, you pick them by the year and whether they are brembo or non-Brembo, not by size. There may be a slight variation in diameter between what they sell and what the OEM brakes are listed as.

 

Sorry about all the numbers it can get dizzy just by looking at them. I found the proper size but was just wondering if upgrading to a bigger size will work with the original calipers, but you (Mike@blackline) have a good point about the brackets.

 

The question comes from this. When I put the year/model, it gave me these options so I assumed it could be done. The site I used was www.carpartswholesale.com

 

yeah a generic parts website wont have specifics like a tuner-oriented parts site will

 

You have to be careful about trying to pick bigger rotors. You risk having them rub on the calipers or the dust shields. If you could find a caliper relocation kit, then all you would be doing is moving the calipers and pads further from the center of the wheel. What you really want is larger pads to contact more of the rotor. That means bigger calipers too.

Stick with what fits. If you need more brake, then consider a complete brake upgrade.

 

QFT. Besides doing some basic upgrades like SS lines and better pads, theres really no reason to beat around the bush of a full system upgrade. costly, but in the meantime, dont spend money on stuff that really isnt going to produce results
