nice pump!
what size SS line you using for this?
as far as strengthing the rack the only thing i could think of was the mounting brackets. i was trying to remember what they looked like from when i had to replace mine. i cant remember if there were any rubber bushings or spacers. i there are id replace them with biliet SS pieces to reduce the possible flex and improve steering input/feedback.
other then that id look at the rod ends and seeing if theres anyway to upgrade them.
if your that close to your knuckle, and your serrious about racing, check out the 99 JDM Galant knuckle upgrade and step up to EVO brakes and wheel studs for the best possible feedback and control
