Hi!
I have 12l4 with some upgrades like blue rear end from IRS,
front lower arms IRS, and untill I drive on slow engine, like 10.5T,
car was great. For modified ... I switch to 12R5.1 and my problems
with t-bar go away
I play a lot of time with 12L4 but better laps I got when I switch to 12R5.1.
Regards!
