How does it compare? Well.. I've got a Silverstone which still feels a lot more 'chuckable' even though it's only front wheel drive & is down a _LOT_ on power compared to the Q4. I spent a while getting the suspension fettled on the silverstone though & the Q4 still needs bits doing. The Q4 feels very heavy in comparison - so it should it's nearly 300kgs heavier! On the plus side, the Q4 has more grip than you can shake a stick at & once rolling is quick. I wish I could combine the two.. a lighter Q4 that revved would be great! (the std Q4 is only really worth taking up to 5,500rpm where the Silverstone was only just coming on cam from 4,500). Oh & I really need Tar-Ox brakes again!
It's strange though, my brother & I drive (raced a bit) both cars back from Halifax & the Q4 wasn't that much quicker if both cars were being driven hard. But if you get caught of cam you've had it wink
