Vixen S2 - seats and seatbelt mountings
Discussion
Looking at fitting MX5 seats instead of the narrow Corbeau roadster seats.
Car is currently at a friends garage being fettled and awaiting a new MOT. Whilst poking about underneath I notice a 2nd set of holes where the original seats were probably mounted.
Are the seats/seatbelts bolted directly through the fibreglass floorpan and are there any reinforcement to the mountings (I had assumed they would be mounted to the chassis in some way but this doesn't appear to be the case)? Will this be secure enough in the event of a prang or should I look at 'beefing' up the mountings in some way?
Any advice gratefully received.

Hi,
have a look to my Homepage www.tvr.at
In the section Rollbar, you can see the plates which i use.
The plates will fitted over the shocks. You can use the plates for the seatbelts.

Hi, If it helps, my vixen seat belts are bolted to rectangular filets that are welded into the corners of the inner and outer chassis rails. I think these are original.
Do NOT bolt your belts into the grp, in the event of an accident they will be totally useless.
The original three point lap and diagonal belt fits onto these mounts at both sides but the top mounting is bolted through the wheelarch grp with a spreader plate both sides, presumably to spread the load in the event of an accident. How effective this would be I wouldn`t like to say but thats how TVR fitted them.
I have, however now fitted a rear roll cage so I have fitted 4 point belts. The top mounting of which now bolts directly into the bottom brace bar, with the bottom two sides bolted into the original filet plates.
If you need any further help drop me a line.
Cheers

From experience (hitting a tree at about 45 - 50 mph) I can tell you that the seat belt mount through the wheel arch works! As for the seat itself, there is (supposed to be) a plywood plate between the layers of the floor glassfibre to stiffen it up. How that really helps I'm not sure! I would suggest fitting spreader plates under the car as per the wheel arch seatbelt mounting.

Interesting! How did the car stand up in general?
Yes, the spreader plate route was something I was looking to do.
Thanks for the suggestions chaps.
Hit tree front left, rolled car, ended up wedged upsidedown between two other trees, thankfully they were closer together than the car was long so it didn't crush me.
Wrote the shell off and put a 1 1/2° twist in the chassis. Apart from that..... fine.

Just wanted to add,,, I've put an additional strap on the chassis to mount the seats. You used to be able to feel the seats lean forward as the floor flexed when braking (not any more!). I too have a rear roll cage fitted which allows the rear harness straps to be mounted.
(My main concern is still the petrol tank though,,,, GULP!)

Metal strap welded to chassis?
How easy is it to fit a rear roll cage? Can it be done without the need to separate chassis & body?
Are you concerned about the tank spliting in a rear impact or it becoming a missile?
Must admit I have been wondering how the Vixen will handle the 26 mile commute which involves 10 miles on the motorway followed by a section of quick A road. I'm hoping I won't feel too vulnerable, but if so will have to consider a possible swap for a Griffith/another Cerb.
