Interesting as i was going to go this set up, what have you gone up against etc etc Ivor?
Just so i get an idea if it's going to be quick enough for me or i have to go KO4 route.
Apart from a track day @ Oulton in November, I've not had a play with much, TBH. Had more tale's with a lot of cars with the old KO3!! My favorite encounters were the new S3 who was barely pulling away up a DC (my turbo was dying at the time, too, LOL), & the E46 M3 who had to let me pass @ Donington, then came over to my garage to see what I'd done to the Golf!

I've spent a lot of time over the last 6 months tweaking it to get it right.
