Eagle F1 GSD3 XL
 

Are these much of an improvement on the GSD3?
Just seen they are on offer at black circles, and that they have a stronger sidewall - a complaint I heard about the old GSD3, but I must say didn't experience at all myself.

its basically the same tyre,all the xl stands for is extra load meening it has a stronger/stiffer casing for more load bearing,and to be honest prodrive ONLY recommend an extra load tyre on the 225/40z18 size fitment on the impreza,
