As my dad (aerospace engineer) would say in his most precise technical terms: "If it ain't broke, don't fix it." The last thing you want is to spend $1400 and have the car turn slower laps due to higher unsprung weight or brake bias issues. Add displacement and if you find that you are incinerating Pagid race pads it will be time for bigger brakes. It will greatly depend on you the driver and your choice of tracks. Regular fresh brake fluid and high temp pads may be the only upgrade you need.

Super Blue racing fluid and new stainless steel braided brake lines made my factory brakes feel like I put in a whole new big red braking system. Amazing firm feel when I hit the brakes hard.

You should definitely try this $120 fix before you spend any more on the car and see what I'm talking about.

I always run Super Blue, flush the brakes frequently, and run PFC pads. The brakes are great right now. I'm only wondering what to do if I add significant HP to the car this off-season. I don't know how much reserve the brakes will have with increased speed at the track.

You may need better brakes up front and you may not.

Why spend the money now? Get the added HP and see how it stops for you and then decide...

unless you have a money tree in the back yard :dance:

S brake conversion & caliper rebuild

Check my thread for updates... going on the track on the 25th and planning to put on the new front brakes after that.

I have experienced brake fade on back roads in my 3.6 1998 Boxster with stock brakes.

And I've experience brake fade in my 1997 Boxster with a stock 2.5 in it and stock brakes.

A lot depends on how you use your brakes and how often you use your brakes and if you downshift effectively.
