Brakes and 22's

[Quizzle23]

Hey Everyone,

I am getting ready to buy a set of 22's for my 06 X5. I was told I would need to get bigger rotors to insure I brake properly. Has any one heard /done this before and if so what is recommended?

Thank You

"break properly"? i hope mine doesn't break at all.....

Lol u know what I mean. I fixed it so maybe you can help out if you have 22s.

[jddssc121]

i honestly don't think you "need" bigger rotors. They were designed to tow 6K, i think they can handle your bigger wheels just fine

Nope not me, I don't like jarring my teeth lose when driving down the road

is this a serious question? u think that changing ur wheels is going to affect ur stopping?

[serge1]

The overall diameter of the wheel/tire combo will not change, right? No need for bigger brakes then

No, you do not have to change your rotors, drilled/slotted rotors are for performance, and average brakes are just enough. Unless you're going to be doing some hard track breaking, I recommend a big break kit.

If someone is telling you that you have to change your rotors for 22'' rims, they are wrong.

Thanks for the info guys. I guess I just have to see if small breaks look stupid or not lol

Not an X5 but this X6 with a BBK with our CV3s really completes the look

If you're really want to hide them better, get rims will many spokes to fill it up.

wheel size DOES affect braking.. and i dont think towing capacity is very relevant here lol.. it is important to make sure your brakes can handle the wheel size change.

also if the overall diameter of the wheel/tire combo changes, then the speedometer will be off.

RIMS don't affect braking, but the tires and the overall diameter of the wheel can, but not the rim size.

FFS people - BRAKES, not BREAKS

Calm down, honest mistake. No one is perfect.

larger wheel size assumes a heavier wheel most of the time, which will affect braking

Yes, there is more unsprung weight but the difference between 20" and 22" is probably minimal and the tire's stopping ability is more a factor. Meaning performance 22s would stop better than all season 20s. Plus the X5 was designed with 20" in mind.

I would also guess the type, quality, and cost of the rims influences the weight. Light 22s would be no heavier than cheap 20s, but I'd assume the OEM 20s are good rims.

OTOH, once the OP installs the 22s, the large open space may look odd and he'd want BBKs for looks.

But no, larger brakes are not a necessity with the 22s.

The wheel shop may be referencing the average SUV that comes with 16s and has poor brakes to begin with. I guarantee the 22s will cause a huge difference in unsprung weight and increased stoping distances as well as the stresses on the system.
