Do larger wheels require different brakes?

[romecaddy24]

I just had 20's put on my car and i was wondering do i need bigger brakes or do the original cts brakes hold.

I think most people have used the same brakes.

I guess it works. Theoretically I think your braking power is less than stock. Not to mention I think it looks silly when you have huge wheels and a tiny rotor.

the brakes are fine, most people do go the drilled/slotted route though for looks behind the wheel, not just looks though, some pretty nice stopping power, also painted calipers would top it all off, there was a pretty descent article robert produced in a snoops thread about time for brakes saying bigger isnt always better, and that drilled rotors are not that practical as they may crack under enough stress, the article suggested simply slotted rotors as your best overall choice
by no means am i an expert on this subject, but no its not like your car is just gonna keep going because you slapped some 20's on there

naa i wouldnt really ... but i have read that stopping distance from 100-0mph may be slightly affected

you don't have to replace them but bigger wheels increase your braking distance. How much all depends on how much heavier.

Cost of replacing rotors, calipers, and pads would be more than the cost of your rims and tires.

I only put on 20's with six spoke split pattern..........they didnt feel any heavier than my stock tires when i picked them up.......braking seems fine.....and i would never try to go from 100-0.

so ur fine , dont worry bout it

[samoskacts03]

there heavier by the plain fact that their bigger, what ya have 17's?? 16's??? thats a whole nother 3-4 inches of rim diameter

Have you noticed as Detroit increases wheel sizes they also increase rotor sizes? The rotating mass of the 20" wheels sets out farther. That's why you loose some HP and Braking. Sure the OEM brakes will stop you but not as fast.

Curious, are the factory brakes on my 04 w/sport pkg 17" wheels the same brakes that are on an 07 sport with factory 18" wheels?

So......what's different? Pads? Rotor size?

It's my understandung the only difference it the pad material. Rotors are the same.
