Frame Rails...any cop?

 I was just surfing when I found this…

Has anyone fitted anything like this before? I keep looking at the spider that ties both sides of the floor together (Gomiata maybe?) and that has a similar rail that the spider fits between.

I’m thinking it may be £99 well spent if it helps reduce the dreaded scuttle shake, especially if P5 follow up the rails with some form of cross brace. When I waxoiled Betsy’s nether-regions last year I noticed my rails are pretty ropey, scuffed and bent in the middle, one too many speed humps methinks!

Any thoughts?..

 

 P5 are highly regarded in the MX5 tuning world, so I doubt that they would sell anything that they haven’t tested personally. Sounds like a good £99 to me

Thanks Geoff,

Always good to have your seal of approval, I’ll await the end of the month, see how many beer tokens are left in the bank and will keep you posted!

“They are so strong, that in simulated testing a 1000N load only deformed them by 62.83 microns” so thats the deformation from a fat man standing on one end - what about realistic loads like, say, the weight of a car.

They may be awsome, but that kind of wishy-washy-not-quite-useful-but-initially-sounds-impressive marketing guff makes me angry. I’m sure it may reduce up to 100% of scuttle shake…

Let us know how good they are when you’ve fitted them, we need an independant test. One thing is for sure - if they make a significant difference they will sell hundreds at that price.

Japanese companies like RS Aizawa have been doing these for years, usually as part of a vehicle refreshment programme. They just seem to use a simple C-section.

Update:

I’ve emailed P5 for some further info; will they be producing an accompanying cross brace to close in the transmission tunnel, do the rails fit the full length of the original ones, will I have to remove the carpets and seats to fit etc etc.

I think for £99 I’m willing to be the lab-rat on this one, just don’t tell Mrs E!
