I drove a 4C Spider for about 35 miles today (it had 20 miles on the clock!), with roof on and off.
Turns out that the 4C Coupe I drove 2 weeks ago has the racing pack with the stiffer suspension.
Spider has standard suspension. I was again very impressed (more so this time) by the damping and the suspension compliance over rough roads. Superb, firm but hardly ever crashy. The benefits of a stiff chassis no doubt.
Spider steering was a revelation too. It still tugs and seeks out cambers and dips, but it's a lot more 'manageable' and less 'violent'. It's less frisky, less frantic and much better resolved for UK roads .. no doubt much of the difference is due to the standard suspension. I came away thinking that the steering was perfect for the car .. chatty, alert and with decent feedback. The trick is to relax and grip the steering just enough so that you can control it when it does 'unexpected' things, and not so tight as to make it seem like you are fighting it, or it is fighting you. Flow with it while retaining connection and control, and it's great. Try to make it flow with you, and you end up having an unsatisfactory experience. With more seat time, I think I could grow to love it.
The other revelation is that the Spider's cloth roof means that it's much less boomy and noisy at motorway speeds than the Coupe -- the noise and echo effect simply seeps out through the roof. For me, the Coupe was borderline unacceptably loud and boomy, to the extent I found it annoying and uncomfortable. The Spider is just fine; still very raw and loud, but nothing annoying or uncomfortable, and in keeping with its character.
As it stands, my 2 main concerns are dealt with, and comprehensively.
Roof down, the wind noise is not too intrusive until you exceed 85mph, at which point it gets a lot wilder. But even then, for me, it's OK. Was a very windy day with lots of cross winds, so there was wind swirling all over the place. I imagine on calmer days, roof down will be a lot of fun without too much assault on your senses.
One thing I noticed roof down (but not up) is how close I am to the header rail .. around 6 inches. Which felt much too close initially, until I got used to it. Pushing the sunvisor towards the windscreen helped to reduce the slight feeling of claustrophobia. If I bought a Spider, I might want to remove the sunvisor altogether.
Strangely today, I noticed the pedals being more offset to the left than what I remember from the Coupe. It felt a bit awkward at first, but by the end of the drive, I no longer noticed it, and it didn't bother me.
The seat recline adjustment is limited. For me, it has to be on maximum recline. For some strange reason, the top of the instrument panel was slightly obscured today (not in the Coupe), but that is no doubt to do with driving position settings.
The dealer is finding out when the Akaprovic exhaust option becomes available.
I am that much closer to ordering a 4C Spider .. it's almost scary.
