I don't want to drag this debate up again but stuck some SO3's on the back yesterday (have SO2's on the front) and they are superb! Feels much more stable and grippy when cornering...mind you the old ones were completely FD!
S03's appear to work well on TVR's with larger tyre sidewalls. My '96 4.0 Chim feels excellent since I had them fitted. Have done 2K miles so far and love em.
JMorgan, Can't understand how you have worn your tyres out in just 3K miles. Any track days? Are they worn evenly??
I used to own a Clio 172. The S03's I had on there were terrible. I switched to Toyos as the tyre of choice. In short, terrible grip and really fast wear.
