Hi Andy,
Thanks for the prompt response, sounds like an ideal solution as I've had a couple of incidences where I've had to brake quickly and my thigh fouls the steering wheel, in addition to the space being a bit tight in the pedal box area. Just one question - would this modification require to be reportable with respect to the insurance on the vehicle? I assume that documentation in the form of a certificate of conformity or some such would be available if you fitted the item.
Victor,
You are posing an interesting question. This is something that we considered carefully when developing the modification and we came to the conclusion that there is no reason to report this change to your insurer - for the following reasons;
1. The declared ‘H’ point for the vehicle has a +/- 25mm tolerance applied to it when checked by the VCA.
2. MG trim engineers are known to have always targeted the top of the box, such that a ‘sagging’ seat will achieve the nominal condition
3. Our modification achieves a H point drop of 20mm.
4. The seat frame itself and the attachments to the body structure are unchanged.
5. The seat belt anchorage points are part of the seat frame, so again are unchanged.
6. The H point reduction is achieved by two modifications
a. By increasing the angle of the centre section which forms the anti-submarine characteristic of the seat cushion (i.e. helps to stops you sliding forwards underneath the seat belt lap strap). We actually increase this feature by lowering the trailing edge of this part.
b. By changing the height of the flexible cushion support.
In summary, we lower the seat cushion within the existing seat frame.
In my opinion, we make the car safer by giving the driver better access to the pedals and steering wheel!
As for a certificate of conformity, then I’m afraid the answer is no. We carry out the modification ourselves (we are both professional engineers) and are confident that the failure modes are unaffected by this work.
I hope that this answers your questions but I quite understand if you do not wish to go ahead with this change.
Thank you for your interest. It makes a pleasant change to be asked some searching questions!
Best regards,
Andy
