It's pretty hard to tell how much headroom I gained over stock as I had a headliner, no rollcage and different seats and seating position etc etc so it's too hard to tell on the headroom side of things, but we have dropped the seat down at least 70mm or so from the depth of the original seat mounting holes, so I guess that in turn means that technically if I mounted the factory seats in (not possible but you know what I mean) that it would amount to 70mm extra headroom.
More importantly, we've moved the seat more towards the middle of the car also which gives just as good an improvement for taller drivers as the side of the roof comes in so quickly that moving closer to the car takes me away from that. Will know if everything has worked out in a week or so once we get the car back from having it's new floor put in.
Re the Tilton pedals, there's a couple of reasons for me. Firstly, my car started life as an auto, so I had no factory pedals, but even if I did, I would still go the Tilton way (floor mount if you're small enough) as they have a built in brake balance bar so it's easy to adjust the brake balance front to rear on the move. Also, with the new driving position, it's easier to mount these in the right place and with the new brakes, it's also easier to choose the right size master cylinders to suit the new calipers......
The advantage of the floor mount is that they offer clutch, brake and accelerator, but with the reverse swing mounts they only offer clutch and brake...... no idea why they don't do one with an accelerator as well. Just going to use the stock accelerator instead, but would have been nice to have all been one unit.
I was going to initially go for the Tilton 900 series pedals, but after a good long chat on the phone to Tilton, they told me to save my money and get the 600's !
I'm from NZ too and I don't even have an NSX (it is a dream), but damn am I proud to have you, that car and that level of craftsmanship in this country! (Sounding like I'm Mr Key)
