[Roadsters] Brake rotors

[Eddie]

Ummm, these are BRAKES we're talking about.  I wouldn't be so quick to 
"weld repair" brake components.  Imagine tooling down the freeway at 
65mph, and suddenly one of your break rotors explode because the metal 
was weakened by welding and grinding...

Not a good scenario. 

It's one thing to use, say, Volvo rotors and turn them down.  OR to use 
or make aftermarket rotors.  But welding and grinding an existing 
rotor?  Sounds like a recipe for disaster.  You run the risk of 
weakening the metal in a pretty critical component, which, if it fails, 
could cause a serious accident.

IF a welded engine part goes, you blow the motor.  A risk of crashing?  
Yeah, sure, MAYBE.  If you don't know how to handle a rear wheel skid, 
AND you don't keep your cool and simply press the clutch in to disengage 
the rear end, MAYBE you'll crash. 

BUT, if a welded BRAKE component goes, you'd be lucky if you didn't crash! 

Just my 2 cents... which isn't even worth half of that...
