This is a tech question along with a rules & regs question, but I didn't feel like making two different threads. I'll be having the roll cage built for the new tub in a few weeks and had a couple questions.
- The cage in the current tub does not have a dash crossbar. There is a stock "dashbar", but nothing welded to the cage. Is this something folks would recommend for the new cage? I'm concerned about it changing the handling of the front end.
- The ITCS weight for the car is 2630. This is what should be used to determine cage tubing right?
- The chart in the GCR says cage tubing for 1701-2699 lbs is 1.5 X .095 or 1.625 x .080. The sentence before the chart says "The following table shows the minimum allowed tubing outer diameter and wall thickness by vehicle weight". Does that mean 1.5 X .120 tubing could be used? Along the same lines, is the 1.75 X .095 or 1.625 X .120 from the 2700 lbs and up legal for lighter cars?
Thanks.
