i run Caltracs with Mopar XHD springs , have done for over 10 years and various power upgrades .
From footbrake to transbrake leaving @4500 and currently back to foot brake .
I would like to try split monos , weight reduction and probably stiffer . BUT i am concerned how they will hold up to daily driver , probably ok , and when i go racing i have rear race wheels , 29.5x10.5R15 PBR , trolley jack , 20L fuel , spare tyre and assorted tools etc in the boot , not sure .
