I am having a front brake job done (pads and rotors) next week. My brake lines are OEM and 15 years old now so I was thinking of having them replaced with stainless steel lines as preventative maintenance + performance mod "while I'm at it".

Is there any performance advantage to replacing only the fronts with stainless steel? Is there any drawbacks to replacing only the fronts? Or should I be doing both the front and rear?

Well, the rear OEM brake lines are also 15 years old, so it makes sense to replace them at the same time. Not only that, but there's less flex in SS brake lines, so leaving the worn (rubber) rears might not allow the brakes to function at an optimum level. Finally, most SS brake kits include both F&R lines anyway, so why not do them both "while you're at it"?

I'm not doing them, the shop is so if they're already having to root around in front I figured I'd just wait to replace the rear lines when I replace the rear pads to save on labor.

I read recently that since stainless lines dont flex like oem it would put more pressure on the old lines to run them together since theres less area to expand at operating temperature. Any truth to that?

Had mine upgraded to SS years ago. Was told they'd be more stable and never give you that 'mushy' brake pedal feeling. Not sure braking in this car is really the place you want to cheap out, but it's your car so YMMV.

No, and I doubt any reputable race source that would state that...
