They handle flipping brilliantly.
Just by lowering mine with 40mm Pi springs, made a huge difference.
Simple homemade mods will tighten the handling even more without spending lots on manufactured parts.

In the wet, however is a different story...............

My m8 has been using his XR2 on track for a few years now. He thought he'd buy a Corsa w/ a 2.0l red top as he was struggling on the straights. He doesn't feel safe running round the track in that, even though the suspension has been set up for the specific track.

The XR2 wins hands down, but just needs the power on the straights.....thats when the Zetec comes in.
