Do you know if the cross-drilled rotors from stoptech have the possibility of warping?

If so can they be resurfaced?

 

Cracking would be a larger concern with cross-drilled.

That's why it makes little sense to drill holes in perfectly good rotors. It does nothing to improve track performance but measurably weakens the rotor.

Looks nice on a show car I guess, but those aren't generally driven very hard.

 

Porsche only drills holes in their Hi-performance brake packages not the standard.

 

Should i be worry now... so drilled!

 

And that means what? Drilled rotors crack and crack easily. Want to see my Brembo rotors from my F after a grand total of three track days?

How about this:



So I guess that implies Porsche only screws their high performance brake owners who don't choose the carbon brakes.

 

My Porsches rotors have 88k miles & zero cracks. Porsche carbon ceramic rotors are drilled.

 

THis is what you call Hellaflush brakes!

 

How many track days do you have on your Porsche? 88k miles implies zero track events.

I never see cracks on anything I only street drive.

 

do bbks that are made for is250 fit the is350s?

 

Yes they fit.

 

Rotora's have different p/n for the is350s and 250s... Luis at L-Tunedparts is not so willing to let me have it due to the different p/n as he wants to ensure fitment... any idea where i can show it to him?

 

I got a new picture hehe . PS LOVE UR BREMBOS PHIL. BALLIN

 

what kind of volks are these? are those the rays progressive mes which are the same as the volk ones but cheaper?

 

yes they are Volk Progressiv ME on the GFM IS350 owned by Javy i believe... and the one with 7 spokes are VOlk GT-7.. (orange bbk)

 

^^^ Spot on, professor!

I'd love to get my hands on DDQuach's black chrome Volks...
