H5-H4 Conversion to do or ???
 

I am in need of a lower valance paint touch up on my 89 Carerra and have been thinking on installing the euro H4. Will there be great benifit v. the stock H5? They look the same, although I have been told that they are dramatically different. Figure this is the time to do since the body shop will be matching the color anyway.

Also, what sort of bulb combo works well for an upgrade (incl. relays) so as to amplify performance but not blind (read offend) oncomming traffic (read cops).?;)

Read up on all the stuff I've done to my car and I can say with no hesitation that H4's were the best money I've ever spent on my 911. AWESOME upgrade. Worth every penny.
