re: E28/E36 M3/E34/E32 brake swappability? **Rob

["Jay Guillermo" <jcguillermo@xxxxxxxxxxx>]

What about a bolt on brake/rotor upgrade to an E30, in particular an '84 
325e?

I recently had an incident where I slammed into the car in front of me.  
The impact wasn't that hard and there was no damage on my car except a 
minor bent on the kidney grill, but I don't want to experience that 
again.  With the kind of braking power a bigger brake/rotor provides i'm 
anxious to find an easy upgrade.

TIA.
