Backdraft RT4 Seat Dimension / Shifter Thread Size

[tennisbum132]

Wondering if anyone might have the above information handy. Looking for seat dimensions as follows:

Seat Cushion:
- Width (left edge to right edge)
- Length (front edge to back where it meets seat back)

Seat Back (sitting surface):
- Width
- Height (Bottom where it meets seat cushion to top)
- Thickness (Top of seat back)
- Radius (length as if following curvature of seat with string)

Shift Knob Thread:

Any help with these measurements would be greatly appreciated!

All the Best,
Jack

There's a BDR dealer about an hour from you in Tomball TX.
You can probably sit in / see an RT4 in person to ck the seat fitment.

For what it's worth, about a month ago was at Radical Roadster and sat in one of the BDR4's that Jame's had to check the foot well space on pedals and thought the seat was to small and i couldn't slide back into it. My car came in last week and when I sat in it the seat felt fine. I'm pretty sure my butt hasn't shrunk in the time between visits. If you have the time it might not be a bad idea to go check it out.My seats are just the standard BD seats.
