Hey Brett, I saw your car down there the other day, it's looking brilliant with the BF front bar on it. What did you get out of your car? Hope your loving it as much as I'm loving mine... Good luck with it Jimmy, the advantage of valve springs is that they allow the tuner to hold the power and torque right to the redline, and in my case that is 6500rpm, my car holds over 300rwkw from about 3600rpm till about 6100rpm, it is literally just insanity... Too right there Robin, I don't want a Good Friday event to happen to me just yet... but Nizpro stage 2 is next and then I want an engine that can hold the rest. Only God now can help my poor 20" tyres... Jeez I wish I'd bought 19's with a 275 rear tyre now... anyone wanna buy some awesome 20's? Jack
