Thanks everyone for the warm welcome. Yes I hope to attend a few meets once lockdown eases. I'll keep an eye on the events page.
I had the 2.7 Cayman, so it was down in power 100bhp or so compared to the Nismo. So there is a noticeable different in power and the zed feels a lot quicker. With the Porsche it really had to be revved hard through the range to get the most out of it, although that was no hardship as the flat 6 sounded great.
The Cayman had 19" wheels so the ride could be a bit bumpy, and although the same size wheels are on the zed the ride feels smoother. I'm really impressed with the handling with the nismo so far, and it doesn't feel too heavy or big compared to the Porsche.
Both are great drivers cars but I'm pleased I made the switch. I also prefer the looks of the Nismo.
