I have the thick front ARB with wide track, uprated springs and stock shocks all round.
Some time ago I removed the rear ARB because, being a Caterham engineering special, the bar achieved a significant proportion of its roll-resistance by burying itself in the aluminum bodywork above the suspension. I did manage to reduce the frequency of impact by bending, fettling and crossing my fingers, but in the end I declared it to be a "useless piece of sh*t" and pulled it off the car. Note that this is one of the older "top mounted" bars. I do not know whether the later "bottom mounted" bars are a simple bolt-in replacement.
Not surprisingly, the car understeers badly under duress. I want to fix that. I could take an axe to the remaining rear bodywork and then re-install the rear ARB. Or I could find a thinner front ARB. Or I could remove the front ARB altogether.
Has anyone swapped from a top mount to a bottom mount bar? Lessons/observations from that experience?
More broadly, has anyone experimented with different front/rear ARB combinations under TRACK conditions? If so please share.
