Actually your better off with the civic's front bar. it will clear the K-series header fine (as long as its off an EX)

so that gives you three size choices

1. 25.4mm
2. 22.0mm
and 3. 15.9mm

Personally for compitition, I prefer the 15.9mm front bar.

hmmm really? i have the 15.9 bar on right now. what would be some cons to upgrading to a larger size ex bar?


and on a side note what class do you run at autox? STS?

I did run STS, but havent ran at all this year due to lack of $$ for tires.

For compitition the cons of increasing the strength of your front bar include, and are not limited to...

1. Increase in understeer.
2. Decrease in potential traction on the front end (the front end can potentially produce less traction then it did before, and though you can tune the car to rotate as it did before the stronger front bar, the cars overall traction budget will have decreased)
and, 3. Increase in corner exit wheel spin (mostly due to the above)

Now there are specific instances where a stiffer front bar can be usefull. Such as if you are running excessivly low spring rates and or Arnt running the nessisary amount of negitive camber to prevent the car from cornering on the tires sidewalls.
