Any member try foam injection subframe on S1 like R3

I drove R3 and S1 back to back on track before
The steering feedback on R3 is amazing , I think due to age of chasic, but one thing Mather a lot could be foam injection subframe
As u can see on my pic, Mazda already try this setup on JDM special edition model
On the pic it say, this change improve 20%of stiffness !!! Sounds too good to be true
Wonder any member try to do this mod on their S1 8 ?

The S1 Shinka model had it, weight + low hp/tq doesn’t make a good combination. Does a NC MX5 have it? No, they’re just smaller, less power, lighter; and faster.

I'll do it for fun. Is it the front or the rear sub frame? Honestly, haven't spent a lot of time down there.

I honestly can't see this making any difference to the stiffness. Maybe dampen out a little noise or high frequency vibration. On the other hand, it's not going to add much weight either.
