I run the 25/25 kit and it is ACE with the iPd lowered springs and good shocks! Turns in like a normal car at 100km/h, simply amazing. The comment on the page about a touch of oversteer is accurate too, which is odd on a 240 that usually has understeer first.
23mm rear bar is 242 GT only and very rare (pretty sure though happy to be corrected here)
