Drag Racing Tech - SFC or TA for Full Bolt On

From your experience, what suspension component will best help my 60' on a full bolt on car... SFC or TA?

Currently cutting a 1.82 w/ M6.

I do not have SFC's on yet , but when I installed my TA, I was actually able to get decent numbers out of my Drag radials, which I had previously thought were junk, they are now working.

both would help. but subframe connectors mostly will help to prevent chassis flex. if your interested i have a brand new set of umi bolt in 3 points which would go well with a tunnel brace mounted torque arm. pm me if your interested.

Each has it's own benefit, but they work better together than without each other.
