Will my 60 foot times be lowered ??

I'm currently re-building my rear. I'm getting .....

31 spline trak-lok
31 spline moser axles
replacing 4.10 gear
upper and lower boxter x2c control arms
full length sub-frame connectors
torque boxes and axle tubes welded

My previous best 60 foot time on nittos with a 2750 rpm launch was a 1.90

With the addition of the 31 spline trak-lok, sub-frame connectors, torque boxes being welded, and upper and lower control arms. How much better of a 60 foot time can i expect if any. Hopefully some since i'm spending a fortune on all this.

Thanks
Josh
