I echo Harry's thoughts..... I also don't like how when you drive the car on, you can't open the doors. That was a stipulation I had when I was purchasing a trailer.
The F/R weight distribution of a 35 is also a consideration.... I know when we load Giant's R35 onto their traditional tilting car trailer, it doesn't tilt back to level until the car is ALL the way forward, very very different to the earlier series GTR cars on the same trailer.
In my humble opinion, you'd be mush better served saving about 12 grand and having a nice tradtional trailer built to suit, with a long bed of around 16ft (as is mine). I don't like the car protruding further rear than the tralier frame.... not nice if you happen to get smacked up the bum by a truck, farks the race car good n proper, bith ends!
My biggest concern would be "the tail leading the dog" with that single axle trailer compounded by the R35's weight distribution. And a tyre blowout wouldn't bear thinking about.
