Minor upgrades for my Civic HX
 

I'm thinking about doing some upgrades to my 1998 Honda HX CVT coupe.

First, any engine upgrades are out of the question. :no: This is because the CVT transmission can't handle more engine power. Besides, the car right now does 0-60 in about 9 seconds, more than enough for freeway onramp acceleration.

Second, I wonder should I considering installing PIAA light bulbs in place of the original halogen light bulbs. I've heard that it might not be a good idea because the headlamp reflector design of 1996-1998 model year Civic are more optimized for regular halogen bulbs, and switching to PIAA bulbs may actually reduce night time visibility. :no:

Finally, what tires should I consider once the Bridgestone RE900's I have on my car now need to be replaced. Note that I will not go to a 15" rim (for 195/55R15 size), given that will cost way too much money for me. :eek: Here are the tires I am seriously considering:

Bridgestone RE910 or RE92
Continental ContiContact Touring CH95
Goodyear Aquatred 3
Michelin X One
Pirelli P6000 Sport Veloce
Yokohama Aegis LS4 or Avid H4

I've heard of lot of good things about the X One, but it's definitely one of the most expensive tires around for the 185/65R14 size.

Comments welcome.
