Contour Enthusiasts Group Archives Forums General Autocross and Open Track BAT 21mm bar?

Check the archives, but yes, I recall some people having the same issues with the BAT bar as the Aussie bar wrt subframe/bracket failure. The great TH suggested to me that I consider reinforcement regardless of what bar I chose.

As for the diameter, check the archives again, but I think the BAT bar was something like 20.4 mm. The stock "19mm" bar is actually 18.x. To confuse matters even more, the early SE "19mm" bar and the later SVT "18mm" bar are, IIRC, exactly the same.

The BAT bar is indeed bigger in diameter and heavier than the SVT bar. I didn't need to use calipers when I swapped bars out. And it makes a *big* difference turning the car too -- remember that diameter in sway bars is a fourth power!!!
