I Have a Is250 but want to do the 350 rotors along with some stainless steel brake lines.
My question is do I have to change the calipers also? Some people told me I don’t have to while others say I have to change the calipers if I change the rotors, thanks for your help.

While at it I’m thinking about getting STOPTECH ROTORS OR POWER SLOT ALONG WITH THE EBC PADS, ALL SUGGESTIONS WELCOME.

Yes, you will also need the IS350 calipers, brake pads, and backing plates if you want to convert to the IS350 rotors.

Thank jeff....

Also note the stock lines are kevlar, going to stainless lines won't be any upgrade at all (unless you look under your car a lot I suppose)

Never looked at them or under the car before lol
