I finally got round to giving the GTV a good blast this evening. It went in to Autolusso last week for Powerflexing as the creaking had to end. As luck would have it a few days before the oil cooler decided it was going to give up the ghost so one big job turned in to two. It rained quite hard on Thursday evening and I didn't fancy seeing quite how much a difference the new bushes made as the roads were wet and greasy.
Then I was round my other half's all weekend so didn't get a chance to try it out until now. It's nice to be able to give it the beans without the fear of the oil falling out of the bottom of the engine or the rear suspension eating itself up! The back end feels a lot more stable now and seems to follow the line of the front better, plus the powdercoated arms look ace peeking out from the back of the car
Thanks again to Ned and the boys, and I'm sorry for keeping you from your Chinese for so long
