I had bits from a c4.1 which I sold on. The vega just looks and feel a more well built car so decided to stick with that
I've actually started to run with green rear spring as standard, it makes the car more predictable from what i've experienced so far - however dropping springs all round is normally the first thing i do.
Weight distribution does feel alot more biased to the front, when jumping more throttle is needed compared to when I ran the SV2 to keep the nose level, which has made me go for a even softer rear end than say the centro runs.
Anti squat I was running two degrees, but towards the end of the day I was told possibly running more would help me. On power seemed OK - however nothing amazing compared to others I was watching. It was more the car over rotating through the corners which I struggled with.
