I was lucky enougth to be in touch of one of the original 1997 World MX4 Prototype car. Run once (just the IFMAR World), the car was in a really good chape. Just few adjustments was necessary to set a good replica of the Masami machine, especially with details as shock upper fixations or others. I just still missing a set of Yokomo 52mm titanium turnbuckles to replace the Lunsford.

Enjoy it 8)

Yep, looks to be 8)

Do you need it, or can it be available ?

I just found a NIP Yokomo molded plastic wing, but just a clear green !

Lovely :) Any chance of posting a pic of the underside of the chassis plate, at the front of the car? Always wondered if the proto had a kick up molded or whatever it had..

Looks like a locked spur. Wondering if the mx4 slipper clutch was developed after this prototype car?

That's a really beautiful car, i love all the machined aluminium and nylon parts, it's obvious that it was a prototype. A very well executed one.

What's that shock-looking thing on the top plate, was it adjustable to tune chassis flex?

I think that was supposed to increase front traction by allowing a certain amount of give in the chassis. Ive never driven the mx4,, but ive driven an mr4bc,, and it was pretty lively up front.

Very cool piece of yokomo history that car. It looks to be near perfect. Does the owner have any more race history on it? The design is quite beautiful. Production models not quite as pretty.
