| Thanks Dave. I did not realize that the F/S bars were different than the regular v8 bars, but it makes sense to run a bit bigger bar in a handling package. --- On Wed, 12/30/09, Dave Mapes <dma...@erols.com> wrote: |

I can't absolutely guarantee it's right, but it seems like it would be.

Rates were caclulated (other than those for the 1.14" and 0.87") in relation
to the 1.14" or 0.87" (whichever was closer on OD) on a percenatge basis.
The applications listed are my opinion based on autocrossing on the 0.870",
0.990", 1.040", 1.090", 1.140", and 1.180" bars. I'll note that Solo
(autocross) set-ups are often much stiffer (and more tail happy) than road
race or Oval set-ups because of the transition (left-right-left) intensive
nature of the courses. Also you need good shocks (NOT KYB) for any of the
T-bars beyond 0.990" to really work and ride well. What bars will work best
for you depands on what tires/wheels you use, what kind of driving you do,
your driving style, and what kind of feedback you like at the wheel and seat
of your pants.
