Forward bite is off too, going down the straight the rear end breaks loose. I used to have great rip coming out of corners, I could clear the triple with ease before, now I need a decent run at it.
Overall the rear end is a mess.

Suggestions appreciated, thanks!
Are these the same springs you were running on your V2 shocks? If so, you'll want to use the 1.7 pistons and heavy oils (37.5/35, or 1 step lighter). This combo will make the big bores feel more like the V2 shocks, but you'll loose a little pack.
If you're already running a full size pack, then don't add weight. Actually, I can't come close to the forward bite that Alex has (even when I've tried his setup). His car is glued to the track, and wheelies where my B4 and RB6 start to get loose.
