I read your post with interest as I have experienced similar issues with
turn-in or understeer. Taking into account that I am not a chassis engineer -
just a novice really - but I have tried a number of bar combinations. (Now you
must remember that my racer is a TR250 with the six so weight and its
distribution are just two diefferences in our cars.
My current setup is a 1 1/16 front bar - Thanks George! - and no rear bar.
With Hoosiers the turn-in is very good with manageable transition to
understeer at the limit. I run very stiff rear springs and the fronts are as
recommends in the comp. manual.
I have never found the car to be stable on the track with a rear sway bar. I
have tried one with three different front bars and have varied the
engagement on the rear bar as well. I could never keep the tail in line.
the set up, it would just feel squirrely up to completely undriveable. I am
believer in the lone front bar and will next try a 1 1/8 diameter.
