Whats the largest Big Brake Upgrade that can be squeezed in a 18" Wheel. I believe the factory rotors are 14".

Looking to maybe use KSport but want to go as big as possible with my 18" wheels.

 

Not sure, but I think it would also depend on the wheel.

Some have a lot more clearance than others on the inside.

 

StopTech has some nice kits too. Their website might have info about wheel sizing...

 

It's not all wheel diameter sizing but a combo of that and the spoke design that will determine clearance. Good companies like Stoptech provides templates you can cut out to see if your particular wheels will clear their kits.

I'm fairly sure you'll be doing a disservice to your Porsche if you go with ksports but if looks are your main priority on a budget, these may fulfill that gap.

 

What about just upgrading to a set of big reds off a turbo/4S?

They work pretty dang well on the track unless you are super hardcore, and you can pick up a set pretty cheap.

 

You'd know that they fit in 18" Porsche wheels too...

 

I have GT3 brakes on mine, they fit and work great!

 

The brembo F50 kit as it's called...

I contacted Brembo and they said on a 18" wheel you can use a 355mm or 356mm rotor.

On a 19" wheel you can use a 380mm.

 

Doing some online comparisons and Brembo Big Brake Kit for a Lamborghini Gallardo is cheaper than a Porsche 996...lol. PORSCHE TAX!
