and thanks for the tow Max, the PB data showed it definitely helped

I always find that following someone reasonably quick on track or when there's a couple of you following each other around for a "Cat & Mouse" session, makes your times drop. It just goes to show how much quicker we can all actually go around.
Now all I need are a new set of Nitron 46mm's with stiffer springs. I stiffened my shocks at Cadwell to compensate for my soft springs, but found that it was "bobbling" a little too much. I would love to go for either 2 or 3 way dampers, but I'm struggling to get my head round translating what the car's doing on track to what adjustments will need to be made on the dampers. Im sure I probably end up not messing with the settings too much. Is there any idiots guide to adjusting dampers...?
I also may get rid of my rear diffuser, not sure why I've been carrying a lump of iron around with me for so long. I also want a decent plywood front splitter. Finally, I have to get an intercom, so that I can get some tuition. What changes do you guy's want to do to your cars? I must also try & sort out my squeally brakes, mind you when you play back the video clips, at least you can hear when the brakes are being trailed or applied! A small bonus?
