The only wrx I have raced was at willowbank test and tune..
I was in a 1ggze corona (and bad bad auto ) - ran a 15.
He ran a 10.09 (on of the quickest wrx's in QLD)
I got a great launch (as good as it could be anyway) and was ahead for about 1.5 seconds.. so i def beat him off the mark.
After that was a different story though (I got to see his time before I finished!)
I've been lead to believe that wrx's (especially worked ones) are quite tricky to lauch well.. In fact they often get a better launch in the wet?
